CHAPTER 1 Introduction 1.1 Overview This chapter introduces the main features and applications of the NBG6616. The NBG6616 extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. You can set up a wireless network with other IEEE 802.11a/b/

g/n/ac compatible devices. The NBG6616 is able to function both 2.4GHz and 5GHz networks at the same time. A range of services such as a firewall and content filtering are also available for secure Internet computing. There are two USB 2.0 ports on the side panel of your NBG6616. You can connect USB (version 2.0 or lower) memory sticks, USB hard drives, or USB devices for file sharing. The NBG6616 automatically detects the USB devices. Note: For the USB function, it is strongly recommended to use version 2.0 or lower USB storage devices (such as memory sticks, USB hard drives) and/or USB devices. Other USB products are not guaranteed to function properly with the NBG6616. 1.2 Applications Your can have the following networks with the NBG6616:

Wired. You can connect network devices via the Ethernet ports of the NBG6616 so that they can communicate with each other and access the Internet. Wireless. Wireless clients can connect to the NBG6616 to access network resources. You can use WPS (Wi-Fi Protected Setup) to create an instant network connection with another WPS-

compatible device. WAN. Connect to a broadband modem/router for Internet access. 1.3 Ways to Manage the NBG6616 Use any of the following methods to manage the NBG6616. WPS (Wi-Fi Protected Setup). You can use the WPS button or the WPS section of the Web Configurator to set up a wireless network with your NBG6616. Web Configurator. This is recommended for everyday management of the NBG6616 using a

(supported) web browser. NBG6616 Users Guide 12 Chapter 1 Introduction 1.4 Good Habits for Managing the NBG6616 Do the following things regularly to make the NBG6616 more secure and to manage the NBG6616 more effectively. Change the password. Use a password thats not easy to guess and that consists of different types of characters, such as numbers and letters. Write down the password and put it in a safe place. Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the NBG6616 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the NBG6616. You could simply restore your last configuration. 1.5 Resetting the NBG6616 If you forget your password or IP address, or you cannot access the Web Configurator, you will need to use the RESET button at the back of the NBG6616 to reload the factory-default configuration file. This means that you will lose all configurations that you had previously saved, the password will be reset to 1234 and the IP address will be reset to 192.168.1.1. 1.5.1 How to Use the RESET Button 1 Make sure the power LED is on. 2 3 Press the RESET button for one to four seconds to restart/reboot the NBG6616. Press the RESET button for longer than five seconds to set the NBG6616 back to its factory-default configurations. 1.6 The WPS Button Your NBG6616 supports Wi-Fi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the Wi-Fi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each devices documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves. You can use the WPS button (

quickly set up a wireless network with strong security.

) on the front panel of the NBG6616 to activate WPS in order to NBG6616 Users Guide 13 Chapter 1 Introduction 1 Make sure the power LED is on (not blinking). 2 Press the WPS button for more than three seconds and release it. Press the WPS button on another WPS-enabled device within range of the NBG6616. Note: You must activate WPS in the NBG6616 and in another wireless device within two minutes of each other. For more information on using WPS, see Section 8.2 on page 56. 1.7 LEDs Figure 1 Front Panel WPS Button WAN Power USB 1/2 LAN 1-4 5G WLAN WPS 2.4G WLAN The following table describes the LEDs.

NBG6616 Users Guide 23 Chapter 3 Connection Wizard 3.3.2 Connection Type: PPPoE Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF

(Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users. Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber's site. By implementing PPPoE directly on the NBG6616 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6616 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access. Figure 10 Internet Connection Type: PPPoE The following table describes the labels in this screen. Table 8 Internet Connection Type: PPPoE LABEL Internet Connection Type DESCRIPTION Select the PPPoE option for a dial-up connection. Get automatically from ISP Select this radio button if your ISP did not assign you a fixed IP address.

Set Up a Wireless Network Using WPS Connect to NBG6616 Wireless Network without WPS Using Multiple SSIDs on the NBG6616 8.2 Set Up a Wireless Network Using WPS This section gives you an example of how to set up wireless network using WPS. This example uses the NBG6616 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card). There are two WPS methods for creating a secure connection via the web configurator or utility. This tutorial shows you how to do both. Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 8.2.1 on page 56. This is the easier method. PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN

(Personal Identification Number) in the NBG6616s interface. See Section 8.2.2 on page 57. This is the more secure method, since one device can authenticate the other. 8.2.1 Push Button Configuration (PBC) 1 Make sure that your NBG6616 is turned on. Make sure the WIFI button (at the back panel of the NBG6616) is pushed in, and that the device is placed within range of your notebook. 2 Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook. 3 4 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button) Log into NBG6616s Web Configurator and press the Push Button in the Configuration >

Network > Wireless LAN 2.4G > WPS Station screen. NBG6616 Users Guide 56 Chapter 8 Tutorials Note: Your NBG6616 has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other. Note: It doesnt matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The NBG6616 sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG6616 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG6616 and wireless client (the NWD210N in this example). Figure 38 Example WPS Process: PBC Method Wireless Client Access Point WITHIN 2 MINUTES SECURITY INFO COMMUNICATION 8.2.2 PIN Configuration When you use the PIN configuration method, you need to use both NBG6616s configuration interface and the clients utilities. 1 2 Launch your wireless clients configuration utility. Go to the WPS settings and select the PIN method to get a PIN number. Enter the PIN number to the PIN field in the Configuration > Network > Wireless LAN 2.4G >

WPS Station screen on the NBG6616. NBG6616 Users Guide 57 Chapter 8 Tutorials 3 Click Start buttons (or button next to the PIN field) on both the wireless client utility screen and the NBG6616s WPS Station screen within two minutes. The NBG6616 authenticates the wireless client and sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG6616 securely. The following figure shows you the example to set up wireless network and security on NBG6616 and wireless client (ex. NWD210N in this example) by using PIN method. Figure 39 Example WPS Process: PIN Method Wireless Client Access Point WITHIN 2 MINUTES 8.3 Connect to NBG6616 Wireless Network without WPS This example shows you how to configure wireless security settings with the following parameters on your NBG6616 and connect your computer to the NBG6616 wireless network.

NBG6616 Users Guide 61 Chapter 8 Tutorials 7 Check the status of your wireless connection in the screen below. 8 If the wireless client keeps trying to connect to or acquiring an IP address from the NBG6616, make sure you entered the correct security key. If the connection has limited or no connectivity, make sure the DHCP server is enabled on the NBG6616. If your connection is successful, open your Internet browser and enter http://www.zyxel.com or the URL of any other web site in the address bar. If you are able to access the web site, your wireless connection is successfully configured. 8.4 Using Multiple SSIDs on the NBG6616 You can configure more than one SSID on a NBG6616. See Section 11.4 on page 97. This allows you to configure multiple independent wireless networks on the NBG6616 as if there were multiple APs (virtual APs). Each virtual AP has its own SSID, wireless security type and MAC filtering settings. That is, each SSID on the NBG6616 represents a different access point/wireless network to wireless clients in the network. Clients can associate only with the SSIDs for which they have the correct security settings. Clients using different SSIDs can access the Internet and the wired network behind the NBG6616 (such as a printer). NBG6616 Users Guide 62 Chapter 8 Tutorials For example, you may set up three wireless networks (A, B and C) in your office. A is for workers, B is for guests and C is specific to a VoIP device in the meeting room.

A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations. Figure 45 LAN and WAN 10.2 What You Can Do Use the Internet Connection screen to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses (Section 10.4 on page 76). Use the Advanced screen to enable multicasting, configure Windows networking and bridge

(Section 10.5 on page 82). 10.3 What You Need To Know The information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your NBG6616. NBG6616 Users Guide 74 Chapter 10 WAN 10.3.1 Configuring Your Internet Connection Encapsulation Method Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the NBG6616, which makes it accessible from an outside network. It is used by the NBG6616 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG6616 tries to access the Internet. If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method). DNS Server Address Assignment Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The NBG6616 can get the DNS server addresses in the following ways. 1 2 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields. If your ISP dynamically assigns the DNS server IP addresses (along with the NBG6616s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. WAN MAC Address The MAC address screen allows users to configure the WAN port's MAC address by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default to select the factory assigned default MAC Address. Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port. NBG6616 Users Guide 75 Chapter 10 WAN Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. Figure 46 Multicast Example In the multicast example above, systems A and D comprise one multicast group. In multicasting, the server only needs to send one data stream and this is delivered to systems A and D. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group - it is not used to carry user data. The NBG6616 supports both IGMP version 1

(IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the NBG6616 queries all directly connected networks to gather group membership. After that, the NBG6616 periodically updates this information. IP multicasting can be enabled/

disabled on the NBG6616 WAN interface in the Web Configurator (WAN). Select None to disable IP multicasting on these interfaces. 10.4 Internet Connection Use this screen to change your NBG6616s Internet access settings. Click Network > WAN from the Configuration menu.

Enter the MTU (Maximum Transmission Unit) size for each packet. If a larger packet arrives, the NBG6616 divides it into smaller fragments. Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When the NBG6616 has an IPv4 WAN address and you set IPv6/IPv4 mode to IPv4 Only, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISPs IPv4 network. The NBG6616 generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the ISPs Border Relay router to connect to the native IPv6 Internet. The local network can also use IPv4 services. The NBG6616 uses its configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet. This is available only when you select IPv4 Only in the IPv6/IPv4 field. Enable 6RD Automatically configured by DHCPC Enable IPv6 rapid deployment to tunnel IPv6 traffic from the local network through the ISPs IPv4 network.

Click Cancel to begin configuring this screen afresh. 10.4.2 PPPoE Encapsulation The NBG6616 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard

(RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the NBG6616 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG6616 does that part of the task. Furthermore, with NAT, all of the LANs computers will have access. NBG6616 Users Guide 79 Chapter 10 WAN This screen displays when you select PPPoE encapsulation.

NBG6616 Users Guide 83 CHAPTER 11 Wireless LAN 11.1 Overview This chapter discusses how to configure the wireless network settings in your NBG6616. The NBG6616 is able to function both 2.4GHz and 5GHz network at the same time. You can have different wireless and wireless security settings for 2.4GHz and 5GHz wireless LANs. Click Configuration > Network > Wireless LAN 2.4G or Wireless LAN 5G to configure to do so. See the appendices for more detailed information about wireless networks. The following figure provides an example of a wireless network. Figure 50 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices

(such as the printer) or with the Internet. Your NBG6616 is the AP. NBG6616 Users Guide 84 Chapter 11 Wireless LAN 11.1.1 What You Can Do Use the General screen to turn the wireless connection on or off, set up wireless security between the NBG6616 and the wireless clients, and make other basic configuration changes

(Section 11.2 on page 89). Use the More AP screen to set up multiple wireless networks on your NBG6616 (Section 11.4 on page 97). Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from connecting to the NBG6616 (Section 11.5 on page 100). Use the Advanced screen to allow intra-BSS networking and set the RTS/CTS Threshold (Section 11.6 on page 102). Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 11.7 on page 102). Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 11.8 on page 103). Use the WPS Station screen to add a wireless station using WPS (Section 11.9 on page 105). Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 11.10 on page 105). 11.1.2 What You Should Know Every wireless network must follow these basic guidelines. Every wireless client in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity. If two wireless networks overlap, they should use different channels. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess. This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network. NBG6616 Users Guide 85 Chapter 11 Wireless LAN MAC Address Filter Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate Users Guide or other documentation. You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings. This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network. User Authentication You can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this. For wireless networks, there are two typical places to store the user names and passwords for each user. In the AP: this feature is called a local user database or a local database. In a RADIUS server: this is a server used in businesses more than in homes. If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users. Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network. Local user databases also have an additional limitation that is explained in the next section. Encryption Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. 1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses. 2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. NBG6616 Users Guide 86 Chapter 11 Wireless LAN The types of encryption you can choose depend on the type of user authentication. (See page 86 for information about this.) Table 29 Types of Encryption for Each Type of Authentication Weakest NO AUTHENTICATION No Security RADIUS SERVER WPA Static WEP WPA-PSK Strongest WPA2-PSK WPA2 For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK. Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network. Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly. Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database. When you select WPA2 or WPA2-PSK in your NBG6616, you can also select an option (WPA/

WPA-PSK Compatible) to support WPA/WPA-PSK as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA/WPA-PSK Compatible option in the NBG6616. Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key. Guest WLAN Guest WLAN allows you to set up a wireless network where users can access to Internet via the NBG6616 (Z), but not other networks connected to the Z. In the following figure, a guest user can access the Internet from the guest wireless network A via Z but not the home or company network N. Note: The home or company network N and Guest WLAN network are independent networks. Note: Only Router mode supports guest WLAN. NBG6616 Users Guide 87 Chapter 11 Wireless LAN Figure 51 Guest Wireless LAN Network A Z N Guest WLAN Bandwidth The Guest WLAN Bandwidth function allows you to restrict the maximum bandwidth for the guest wireless network. Additionally, you can also define bandwidth for your home or office network. An example is shown next to define maximum bandwidth for your networks (A is Guest WLAN and N is home or company network.) Figure 52 Example: Bandwidth for Different Networks N 600 kbps 100 kbps 300 kbps A WPS WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification NBG6616 Users Guide 88 Chapter 11 Wireless LAN Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 8.2 on page 56. 11.2 General Wireless LAN Screen Use this screen to configure the SSID and wireless security of the wireless LAN. Note: If you are configuring the NBG6616 from a computer connected to the wireless LAN and you change the NBG6616s SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the NBG6616s new settings. Click Network > Wireless LAN 2.4G/5G to open the General screen.

Refer to the Connection Wizard chapter for more information on channels. This option is only available if Auto Channel Selection is disabled. Select this check box for the NBG6616 to automatically choose the channel with the least interference. Deselect this check box if you wish to manually select the channel using the Channel Selection field. This displays the channel the NBG6616 is currently using. Auto Channel Selection Operating Channel Channel Width Select the wireless channel width used by NBG6616. A standard 20MHz channel offers transfer speeds of up to 144Mbps (2.4GHz) or 217Mbps

(5GHZ) whereas a 40MHz channel uses two standard channels and offers speeds of up to 300Mbps (2.4GHz) or 450Mbps (5GHZ). Because not all devices support 40 MHz channels, select Auto 20/40MHz to allow the NBG6616 to adjust the channel bandwidth automatically. 40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. Select 20MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding. 802.11 Mode If you are in the Wireless LAN 2.4G > General screen, you can select from the following:

For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network. The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses to the devices (A to D) connected to your NBG6616. The ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D going out to the Internet use the IP address of the NBG6616, which is 192.168.1.1. Figure 75 NAT Example A: 192.168.1.33 FTP, Telnet, SNMP Ports 21 to 25 B: 192.168.1.34 Port 80 C: 192.168.1.35 LAN WAN 192.168.1.1 IP address assigned by ISP This chapter discusses how to configure NAT on the NBG6616. Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the NBG6616. 14.1.1 What You Can Do Use the General screen to enable NAT (Section 14.2 on page 118). NBG6616 Users Guide 116 Chapter 14 NAT Use the Port Forwarding screen to set a default server and change your NBG6616s port forwarding settings to forward incoming service requests to the server(s) on your local network

(Section 14.3 on page 119). Use the Port Trigger screen to change your NBG6616s trigger port settings (Section 14.5.3 on page 124). 14.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. Inside/Outside This denotes where a host is located relative to the NBG6616, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Global/Local This denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side. Note: Inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information. Table 49 NAT Definitions ITEM Inside DESCRIPTION This refers to the host on the LAN. Outside This refers to the host on the WAN. Local Global This refers to the packet address (source or destination) as the packet travels on the LAN. This refers to the packet address (source or destination) as the packet travels on the WAN. Note: NAT never changes the IP address (either local or global) of an outside host. What NAT Does In the simplest form, NAT changes the source IP address in a packet received from a subscriber

(the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed. The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local NBG6616 Users Guide 117 Chapter 14 NAT network and make them accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall protection. With no servers defined, your NBG6616 filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT). How NAT Works Each packet has two addresses a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address in each packet and then forwards it to the Internet. The NBG6616 keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this. Figure 76 How NAT Works 14.2 General Use this screen to enable NAT and set a default server. Click Network > NAT to open the General screen. Figure 77 Network > NAT > General NBG6616 Users Guide 118 Chapter 14 NAT The following table describes the labels in this screen. Table 50 Network > NAT > General LABEL Network Address Translation (NAT) DESCRIPTION Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).

Click Cancel to begin configuring this screen afresh. 14.3 Port Forwarding Screen Use this screen to forward incoming service requests to the server(s) on your local network and set a default server. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. Port forwarding allows you to define the local servers to which the incoming services will be forwarded. To change your NBG6616s port forwarding settings, click Network > NAT > Port Forwarding. The screen appears as shown. Note: If you do not assign a Default Server, the NBG6616 discards all packets received for ports that are not specified in this screen or remote management. Refer to Appendix C on page 228 for port numbers commonly used for particular services.

NBG6616 Users Guide 122 Chapter 14 NAT 14.5 Technical Reference The following section contains additional technical information about the NBG6616 features described in this chapter. 14.5.1 NATPort Forwarding: Services and Port Numbers A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Use the Port Forwarding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. 14.5.2 NAT Port Forwarding Example Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. Figure 81 Multiple Servers Behind NAT Example NBG6616 Users Guide 123 Chapter 14 NAT 14.5.3 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service

(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG6616 records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the NBG6616's WAN port receives a response with a specific port number and protocol ("incoming"

port), the NBG6616 forwards the traffic to the LAN IP address of the computer that sent the request. After that computers connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application. 14.5.4 Trigger Port Forwarding Example The following is an example of trigger port forwarding. Figure 82 Trigger Port Forwarding Process: Example Janes computer Real Audio Server Port 7070 1 2 3 4 Jane requests a file from the Real Audio server (port 7070). Port 7070 is a trigger port and causes the NBG6616 to record Janes computer IP address. The NBG6616 associates Jane's computer IP address with the "incoming" port range of 6970-7170. The Real Audio server responds using a port number ranging between 6970-7170. The NBG6616 forwards the traffic to Janes computer IP address. 5 Only Jane can connect to the Real Audio server until the connection is closed or times out. The NBG6616 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP

(Transfer Control Protocol/Internet Protocol). NBG6616 Users Guide 124 Chapter 14 NAT 14.5.5 Two Points To Remember About Trigger Ports 1 2 Trigger events only happen on data that is coming from inside the NBG6616 and going to the outside. If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN cant trigger it. NBG6616 Users Guide 125 CHAPTER 15 DDNS 15.1 Overview DDNS services let you use a domain name with a dynamic IP address. 15.1.1 What You Need To Know The following terms and concepts may help as you read through this chapter. What is DDNS?

Dynamic Domain Name Service (DDNS) services let you use a fixed domain name with a dynamic IP address. Users can always use the same domain name instead of a different dynamic IP address that changes each time to connect to the NBG6616 or a server in your network. Note: The NBG6616 must have a public global IP address and you should have your registered DDNS account information on hand. 15.2 General To change your NBG6616s DDNS, click Network > DDNS. The screen appears as shown. Figure 83 Dynamic DNS NBG6616 Users Guide 126 Chapter 15 DDNS The following table describes the labels in this screen.

NBG6616 Users Guide 127 CHAPTER 16 Static Route 16.1 Overview This chapter shows you how to configure static routes for your NBG6616. The NBG6616 usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the NBG6616 send data to devices not reachable through the default gateway, use static routes. For example, the next figure shows a computer (A) connected to the NBG6616s LAN interface. The NBG6616 routes most traffic from A to the Internet through the NBG6616s default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN.

NBG6616 Users Guide 130 CHAPTER 17 Firewall 17.1 Overview Use these screens to enable and configure the firewall that protects your NBG6616 and your LAN from unwanted or malicious traffic. Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall:

allows traffic that originates from your LAN computers to go to all of the networks. blocks traffic that originates on the other networks from going to the LAN. The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic initiated from the WAN is blocked (3 and 4). Figure 87 Default Firewall Action LAN WAN A 1 2 3 4 17.1.1 What You Can Do Use the General screen to enable or disable the NBG6616s firewall (Section 17.2 on page 133). Use the Services screen enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them (Section 17.3 on page 133). 17.1.2 What You Need To Know The following terms and concepts may help as you read through this chapter. NBG6616 Users Guide 131 Chapter 17 Firewall What is a Firewall?

Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself. Stateful Inspection Firewall Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises. About the NBG6616 Firewall The NBG6616s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks. It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab under Firewall and then click the Enable Firewall check box). The NBG6616's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The NBG6616 can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The NBG6616 is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN. The NBG6616 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband

(cable or DSL) modem to the Internet. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service. Guidelines For Enhancing Security With Your Firewall Change the default password via Web Configurator. Think about access control before you connect to the network in any way, including attaching a modem to the port. Limit who can access your router. 1 2 3 NBG6616 Users Guide 132 Chapter 17 Firewall 4 Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5 6 7 For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. Protect against IP spoofing by making sure the firewall is active. Keep the firewall in a secured (locked) room. 17.2 General Screen Use this screen to enable or disable the NBG6616s firewall, and set up firewall logs. Click Security

Keyword Blocking URL Checking The NBG6616 checks the URLs domain name (or IP address) and file path separately when performing keyword blocking. The URLs domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw. The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php. Since the NBG6616 checks the URLs domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/

pressroom.php, the NBG6616 would find tw in the domain name (www.zyxel.com.tw). It would also find news in the file path (news/pressroom.php) but it would not find tw/news. 19.2 Parental Control Screen Use this screen to enable parental control, view the parental control rules and schedules.

See the appendices for information on how to access and use the command interpreter. Domain Name or IP Address URL Checking By default, the NBG6616 checks the URLs domain name or IP address when performing keyword blocking. This means that the NBG6616 checks the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches for keywords within www.zyxel.com.tw. Full Path URL Checking Full path URL checking has the NBG6616 check the characters that come before the last slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking searches for keywords within www.zyxel.com.tw/news/. Use the ip urlfilter customize actionFlags 6 [disable | enable] command to extend (or not extend) the keyword blocking search to include the URL's full path. NBG6616 Users Guide 142 Chapter 19 Parental Control File Name URL Checking Filename URL checking has the NBG6616 check all of the characters in the URL. For example, filename URL checking searches for keywords within the URL www.zyxel.com.tw/

news/pressroom.php. Use the ip urlfilter customize actionFlags 8 [disable | enable] command to extend (or not extend) the keyword blocking search to include the URL's complete filename.

Table 68 Media Bandwidth Management Setup: Services SERVICE FTP DESCRIPTION File Transfer Program enables fast transfer of files, including large files that may not be possible by e-mail. WWW E-Mail VoIP (SIP) BitTorrent Gaming The World Wide Web (WWW) is an Internet system to distribute graphical, hyper-linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for the World Wide Web. The Web is not synonymous with the Internet; rather, it is just one service on the Internet. Other services on the Internet include Internet Relay Chat and Newsgroups. The Web is accessed through use of a browser. Electronic mail consists of messages sent through a computer network to specific groups or individuals. Here are some default ports for e-mail:

POP3 - port 110 IMAP - port 143 SMTP - port 25 HTTP - port 80 Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP is transported primarily over UDP but can also be transported over TCP. BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large software and media files. BitTorrent requires you to search for a file with a searching engine yourself. It distributes files by corporation and trading, that is, the client downloads the file in small pieces and share the pieces with other peers to get other half of the file. Online gaming services lets you play multiplayer games on the Internet via broadband technology. As of this writing, your NBG6616 supports Xbox, Playstation, Battlenet and MSN Game Zone. NBG6616 Users Guide 153 CHAPTER 22 Remote Management 22.1 Overview This chapter provides information on the Remote Management screens.

NBG6616 Users Guide 157 CHAPTER 23 Universal Plug-and-Play (UPnP) 23.1 Overview This chapter introduces the UPnP feature in the web configurator. Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. 23.2 What You Need to Know UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. 23.2.1 NAT Traversal UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:

Dynamic port mapping Learning public IP addresses Assigning lease times to mappings Windows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT. 23.2.2 Cautions with UPnP The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the NBG6616 allows multicast messages on the LAN only. NBG6616 Users Guide 158 Chapter 23 Universal Plug-and-Play (UPnP) All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 23.3 UPnP Screen Use this screen to enable UPnP on your NBG6616. Click Management > UPnP to display the screen shown next. Figure 103 Management > UPnP The following table describes the fields in this screen. Table 72 Management > UPnP LABEL UPnP DESCRIPTION Select Enable to activate UPnP.

The following figure is an overview of the NBG6616s file-sharing server feature. Computers A and B can access files on a USB device (C) which is connected to the NBG6616 (D). Figure 114 File Sharing Overview B A C D 24.2 What You Can Do Use the DLNA screen to use the NBG6616 as a media server and allow DLNA-compliant devices to play media files stored in the attached USB device (Section 24.5 on page 167). Use the SAMBA screen to enable file-sharing via the NBG6616 using Windows Explorer or the workgroup name. This screen also allow you to configure the workgroup name and create user accounts (Section 24.6 on page 167). Use the FTP screen to allow file sharing via the NBG6616 using FTP and create user accounts

(Section 24.7 on page 169). 24.3 What You Need To Know DLNA The Digital Living Network Alliance (DLNA) is a group of personal computer and electronics companies that works to make products compatible in a home network. DLNA clients play files stored on DLNA servers. The NBG6616 can function as a DLNA-compliant media server and stream files to DLNA-compliant media clients without any configuration. NBG6616 Users Guide 165 Chapter 24 USB Media Sharing Workgroup name This is the name given to a set of computers that are connected on a network and share resources such as a printer or files. Windows automatically assigns the workgroup name when you set up a network. File Systems A file system is a way of storing and organizing files on your hard drive and storage device. Often different operating systems such as Windows or Linux have different file systems. The file-sharing feature on your NBG6616 supports New Technology File System (NTFS), File Allocation Table (FAT) and FAT32 file systems. Windows/CIFS Common Internet File System (CIFS) is a standard protocol supported by most operating systems in order to share files across the network. CIFS runs over TCP/IP but uses the SMB (Server Message Block) protocol found in Microsoft Windows for file and printer access; therefore, CIFS will allow all applications, not just Web browsers, to open and share files across the Internet. The NBG6616 uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS compatible computers can access the USB file storage devices connected to the NBG6616. CIFS protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to your systems specifications for CIFS compatibility). Samba SMB is a client-server protocol used by Microsoft Windows systems for sharing files, printers, and so on. Samba is a free SMB server that runs on most Unix and Unix-like systems. It provides an implementation of an SMB client and server for use with non-Microsoft operating systems. File Transfer Protocol This is a method of transferring data from one computer to another over a network such as the Internet. 24.4 Before You Begin 1 2 Make sure the NBG6616 is connected to your network and turned on. Connect the USB device to one of the NBG6616s USB ports. The NBG6616 detects the USB device and makes its contents available for browsing. If you are connecting a USB hard drive that comes with an external power supply, make sure it is connected to an appropriate power source that is on.

The Internet connection is slow or intermittent. 1 2 3 4 There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.7 on page 14. If the NBG6616 is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications. Check the signal strength. If the signal strength is low, try moving the NBG6616 closer to the AP if possible, and look around to see if there are any devices that might be interfering with the wireless network (for example, microwaves, other wireless networks, and so on). Reboot the NBG6616. If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions. Advanced Suggestion NBG6616 Users Guide 187 Chapter 26 Troubleshooting Check the settings for QoS. If it is disabled, you might consider activating it. 26.5 Resetting the NBG6616 to Its Factory Defaults If you reset the NBG6616, you lose all of the changes you have made. The NBG6616 re-loads its default settings, and the password resets to 1234. You have to make all of your changes again. You will lose all of your changes when you push the RESET button. To reset the NBG6616:

1 Make sure the power LED is on. 2 3 Press the RESET button for one to four seconds to restart/reboot the NBG6616. Press the RESET button for longer than five seconds to set the NBG6616 back to its factory-default configurations. If the NBG6616 restarts automatically, wait for the NBG6616 to finish restarting, and log in to the Web Configurator. The password is 1234. If the NBG6616 does not restart automatically, disconnect and reconnect the NBG6616s power. Then, follow the directions above again. 26.6 Wireless Connections I cannot access the NBG6616 or ping any computer from the WLAN. 1 Make sure the wireless LAN is enabled on the NBG6616. 2 Make sure the wireless adapter on your computer is working properly. 3 Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports the same wireless standard as the NBG6616. 4 Make sure your computer (with a wireless adapter installed) is within the transmission range of the NBG6616. 5 Check that both the NBG6616 and the wireless adapter on your computer are using the same wireless and wireless security settings. 6 Make sure traffic between the WLAN and the LAN is not blocked by the firewall on the NBG6616. NBG6616 Users Guide 188 Chapter 26 Troubleshooting 7 Make sure you allow the NBG6616 to be remotely accessed through the WLAN interface. Check your remote management settings. See the chapter on Wireless LAN in the Users Guide for more information. I set up URL keyword blocking, but I can still access a website that should be blocked. Make sure that you enable parental control in the Parental Control screen, set up rules and turn on the rules. Make sure that the keywords that you type are listed in the rules Keyword List. If a keyword that is listed in the Keyword List is not blocked when it is found in a URL, customize the keyword blocking using commands. See the Customizing Keyword Blocking URL Checking section in the Parental Control chapter. I cannot access the Web Configurator after I switched to AP mode. When you change from router mode to AP mode, your computer must have an IP address in the range between 192.168.1.3 and 192.168.1.254. Refer to Appendix B on page 200 for instructions on how to change your computers IP address. What factors may cause intermittent or unstabled wireless connection? How can I solve this problem?

The following factors may cause interference:

Obstacles: walls, ceilings, furniture, and so on. Building Materials: metal doors, aluminum studs. Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices. To optimize the speed and quality of your wireless connection, you can:

Move your wireless device closer to the AP if the signal strength is low. Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones. Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client. Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary. Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet. NBG6616 Users Guide 189 Chapter 26 Troubleshooting Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the antennas in different directions and check which provides the strongest signal to the wireless clients. 26.7 USB Device Problems I cannot access or see a USB device that is connected to the NBG6616. 1 Disconnect the problematic USB device, then reconnect it to the NBG6616. 2 3 4 5 6 Ensure that the USB device has power. Check your cable connections. Restart the NBG6616 by disconnecting the power and then reconnecting it. If the USB device requires a special driver, install the driver from the installation disc that came with the device. After driver installation, reconnect the USB device to the NBG6616 and try to connect to it again with your computer. If the problem persists, contact your vendor. What kind of USB devices do the NBG6616 support?

1 It is strongly recommended to use version 2.0 or lower USB storage devices (such as memory sticks, USB hard drives) and/or USB devices. Other USB products are not guaranteed to function properly with the NBG6616.
