Consult the Glossary for definitions of the terminology used in this section. THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The TEW-812DRU provides various transmission (data) rate options for you to select. In most networking scenarios, the factory default Best (automatic) setting proves the most efficient. This setting allows your TEW-812DRU to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the TEW-812DRU automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the TEW-812DRU gradually increases the transmission (data) rate again until it reaches the highest available transmission rate. Types of Wireless Networks Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infra-

structure mode, wireless devices communicate to a wired LAN via access points. Each access point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set

(ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer mode), wireless devices communicate with each other directly and do not use an access point. This is an Independent BSS (IBSS). To connect to a wired network within a coverage area using access points, set the operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS) mode. AD-HOC (IBSS) NETWORK Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS). To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each station. 9 10 When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS). In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network. In an ESS environment, users are able to move from one access point to another without losing the 11 connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client devices automatically switches to the channel used in BSS (2). Roaming in an ESS network diagram 12 Introduction The TEW-812DRU 802.11ac(draft 2.0)3x3 Gigabit Wireless Router is an high-performance, wireless router that supports high-speed wireless networking at home, at work or in public places. Unlike most routers, the TEW-812DRU provides data transfers at up to 1.3Gbps when using 11AC connection. This router is also back compatible with 802.11n or 802.11g or 11b devices. This means that you do not need to change your entire network to maintain connectivity. You may sacrifice some of 11acs speed when you mix 11ac /11n and 11b/g devices, but you will not lose the ability to communicate when you incorporate the 11ac standard into your 11a/b/g/n network. You may choose to slowly change your network by gradually replacing the 11a/b/g/n devices with 11ac devices.

Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:

1 Keep the number of walls and ceilings between the TEW-812DRU and other network devices to a minimum - each wall or ceiling can reduce your wireless products range from 3-90 feet

(1-30 meters.) Position your devices so that the number of walls or ceilings is minimized. 2 Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception. 3 Building Materials can impede the wireless signal - a solid metal door or aluminum studs may have a negative effect on range. Try to position wireless devices and computers with wireless adapters so that the signal passes through drywall or open doorways and not other materials. 4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme RF noise. Getting Started For a typical wireless setup at home, please do the following:

1. You will need broadband Internet access (a Cable or DSL-subscriber line into your home or office) 2. Consult with your Cable or DSL provider for proper installation of the modem. 3. Connect the Cable or DSL modem to the TEW-812DRU Router (WAN port). 4. Ethernet LAN ports of the TEW-812DRU are Auto MDI/MDIX and will work with both Straight-Through and Cross-Over cable.

20 Select the 2.4G & 5G security mode 21 Enter your password 22 Press Apply 23 Network Network: WAN Setting WAN Connection Type There are several connection types to choose from: Static IP, DHCP, PPPoE, PPTP, L2TP, and Russia PPTP. If you are unsure of your connection method, please contact your Internet Service Provider. Static Used when your ISP provides you a set IP address that does not change. The IP information is manually entered in your IP configuration settings. You must enter the IP address, Subnet Mask, Gateway, Primary DNS Server, and Secondary DNS Server. Your ISP provides you with all of this information. DHCP 24 A method of connection where the ISP assigns your IP address when your router requests one from the ISP's server. Host Name: Some ISP's may check your computer's Host Name. The Host Name identifies your system to the ISP's server. PPPoE Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet) connection. DSL providers typically use this option. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet. Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to set the reconnection mode. The settings are:

Always on: A connection to the Internet is always maintained. On demand: A connection to the Internet is made as needed. Manual: You have to open up the Web-based management interface and click the Connect button manually any time that you wish to connect to the Internet. Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual"

reconnect modes. L2TP 25 L2TP (Layer Two Tunneling Protocol) uses a virtual private network to connect to your ISP. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet. L2TP Server IP Address: The ISP provides this parameter, if necessary. The value may be the same as the Gateway IP Address. Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to set the reconnection mode. The settings are:

Always on: A connection to the Internet is always maintained. On demand: A connection to the Internet is made as needed. Manual: You have to open up the Web-based management interface and click the Connect button manually any time that you wish to connect to the Internet. Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual"

reconnect modes. WAN Interface IP Type Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for the following fields for WAN Interface IP Setting: IP Address, Subnet Mask , Default Gateway. Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this option. PPTP PPTP (Point to Point Tunneling Protocol) uses a virtual private network to connect to your ISP. This method of connection is primarily used in Europe. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet. PPTP Server IP Address: The ISP provides this parameter, if necessary. The value may be the same as the Gateway IP Address. Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to set the reconnection mode. The settings are:

Always on: A connection to the Internet is always maintained. On demand: A connection to the Internet is made as needed. Manual: You have to open up the Web-based management interface and click the Connect button manually any time that you wish to connect to the Internet. Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual"

reconnect modes. WAN Interface IP Type 26 Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for the following fields for WAN Interface IP Setting: IP Address, Subnet Mask , Default Gateway, and optional for DNS Server Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this option. MAC Address Clone Each networking device has it's own unique MAC address defined by the hardware manufacturer. Some ISP's may check your computer's MAC address. Some ISP's record the MAC address of the network adapter in the computer or router used to initially connect to their service. The ISP will then only grant Internet access to requests from a computer or router with this particular MAC address. This router has a different MAC address than the computer or router that initially connected to the ISP. If you need to change the MAC address of the rounter's WAN-side Ethernet interface, either type in an alternate MAC address (for example, the MAC address of the router initially connected to the ISP) or copy the MAC address of a PC. To copy the MAC address of the computer that initially connected to the ISP, connect to the router using that computer and click the Clone Your PC's MAC Address button. The WAN interface will then use the MAC address of the network adapter in your computer. 27 Network: LAN Setting IP Address The IP address of the this device on the local area network. Assign any unused IP address in the range of IP addresses available for the LAN. Subnet Mask The subnet mask of the local area network. Enable DHCP Server Once your router is properly configured and this option is enabled, the DHCP Server will manage the IP addresses and other network configuration information for computers and other devices connected to your Local Area Network. There is no need for you to do this yourself. 28 The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to "DHCP" or "Obtain an IP address automatically". When you set Enable DHCP Server, the following options are displayed. DHCP IP Address Range These two IP values (Start and End) define a range of IP addresses that the DHCP Server uses when assigning addresses to computers and devices on your Local Area Network. Any addresses that are outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices or devices that cannot use DHCP to obtain network address details automatically. It is possible for a computer or device that is manually configured to have an address that does reside within this range. In this case the address should be reserved, so that the DHCP Server knows that this specific address can only be used by a specific computer or device. Your router, by default, has a static IP address of 192.168.10.1. This means that addresses 192.168.10.2 to 192.168.10.254 can be made available for allocation by the DHCP Server. Subnet Mask The subnet mask of the local area network. Gateway The IP address of the router on the local area network. For example, 192.168.10.1. DHCP Lease Time The amount of time that a computer may have an IP address before it is required to renew the lease. The lease functions just as a lease on an apartment would. The initial lease designates the amount of time before the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is established. If the lease expires and the address is no longer needed than another tenant may use the address. IP Address:

The LAN address that you want to reserve. MAC Address To input the MAC address of your system, enter it in manually or connect to the router's Web-Management interface from the system and click the Copy Your PC's MAC Address button. A MAC address is usually located on a sticker on the bottom of a network device. The MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network device is a computer and the network card is already located inside the computer, you can connect to the 29 router from the computer and click the Copy Your PC's MAC Address button to enter the MAC address. 30 Network: IPv6 Setting 6to4 6to4 is provided as a transition for migrating from IPv4 to IPv6. It allows IPv6 packets to be transmitted over an IPv4 network through the automatic tunneling technology, and routes traffic between 6to4 and IPv6 networks. 31 Network: QoS QoS Setup 32 There are several Maximum upload bandwidth to choose or user defined. QoS Group There are several group of QoS rate and ceil upload bandwidth to setup. You can setup QoS per different protocol Application. QoS List 33 Network: DHCP Client List In this section you can see the connected LAN devices are currently receiving an IP addresses. 34 Wireless Wireless: Basic 35 Radio On/Off This indicates the wireless operating status. The wireless can be turned on or off by the slide switch. When the radio is on, the following parameters are in effect. Wireless Mode If all of the wireless devices you want to connect with this router can connect in the same transmission mode, you can improve performance slightly by choosing the appropriate wireless mode. If you have some devices that use a different transmission mode, choose the appropriate wireless mode. The TEW-812DRU supports 2.4GHz/5GHz wireless networks. There are many different configuration options available to choose from. Use the drop down list to select the wireless mode. Note: One wireless mode can be selected can select at any one time. This means that you can only select one of the operating frequency at a time. Wireless Network Name (SSID) When you are browsing for available wireless networks, this is the name that will appear in the list (unless Visibility Status is set to Invisible, see below). This name is also referred to as the SSID. For security purposes, it is highly recommended to change from the pre-configured network name. Add up to three additional SSIDs to create virtual wireless networks from one wireless Router Access Point device. Add Additional Wireless Network Name (SSID) To add additional wireless Network Names simply add the name to the Multiple SSID field and click on apply at the bottom of the page. When finished, go to the Security section in this Users Guide for wireless security configuration. Frequency (Channel) A wireless network uses specific channels in the wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network. Wireless Distribution System (WDS) When WDS is enabled, this access point functions as a wireless repeater and is able to wirelessly communicate with other APs via WDS links. A WDS link is bidirectional; so this AP must know the MAC Address (creates the WDS link) of the other AP, and the other AP must have a WDS link back to this AP. Make sure the APs are configured with same channel.

(Note that WDS security is incompatible with mixed mode, like WPAPSK+WPA2PSK mixed, WEP AUTO and 802.1x, both feature cannot be used at the same time). Configuring WDS with TEW-812DRU Enable the option for WDS and input the MAC Address of the wireless device that also supports WDS in to the blank fields. You can add up to four additional devices in the spaces provided. 36 Click on apply at the bottom of the page, to apply your setting changes. Enable the security seeing in security page, each WDS APs need to use same security setting.

(Note: WDS supports wireless g/n modes. The use multiple Access Point will reduces the overall network throughput to the TEW-812DRU. 37 Wireless: Advanced Beacon Interval Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon Period value between 20 and 1000. The default value is set to 100 milliseconds. DTIM A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the wireless router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255. Fragmentation Threshold Wireless frames can be divided into smaller units (fragments) to improve performance in the presence of RF interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor performance. RTS Threshold When an excessive number of wireless packet collisions are occurring, wireless performance can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless transmitter will begin to send RTS frames (and wait for CTS) when data frame size 38 in bytes is greater than the RTS Threshold. This setting should remain at its default value of 2346 bytes. Short Preamble and Slot Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation. 39 Wireless: Security Security Mode Unless one of these encryption modes is selected, wireless transmissions to and from your wireless network can be easily intercepted and interpreted by unauthorized users. WPA-

Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security standards published by the Wi-Fi Alliance. The WPA Mode further refines the variant that the router should employ. WPA Mode: WPA is the older standard; select this option if the clients that will be used with the router only support the older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. With the "WPA2" option, the router tries WPA2 first, but falls back to 40 WPA if the client only supports WPA. With the "WPA2 Only" option, the router associates only with clients that also support WPA2 security. Cipher Type: The encryption algorithm used to secure the data communication. TKIP (Temporal Key Integrity Protocol) provides per-packet key generation and is based on WEP. AES

(Advanced Encryption Standard) is a very secure block based encryption. With the "TKIP and AES" option, the router negotiates the cipher type with the client, and uses AES when available. Group Key Update Interval: The amount of time before the group key used for broadcast and multicast data is changed. WPA-PSK This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK). Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII (American Standard Code for Information Interchange) format at both ends of the wireless connection. It cannot be shorter than eight characters, although for proper security it needs to be of ample length and should not be a commonly known phrase. This phrase is used to generate session keys that are unique for each wireless client. Wireless MAC Filtering Choose the type of MAC filtering needed. Turn MAC Filtering Disable: When "Disable" is selected, MAC addresses are not used to control network access. Add MAC Filtering Rule Use this section to add MAC addresses to the list below. MAC Address Enter the MAC address of a computer that you want to control with MAC filtering. Computers that have obtained an IP address from the router's DHCP server will be in the DHCP Client List. Select a device from the drop down menu. The rule of thumb:

In mixed mode, multicast key has to be TKIP, but unicast key can be different per stations. In WPA or WPA2 only mode, unicast and multicast key can be only AES for WPA2, and TKIP for WPA. (AES means the unicast and multicast key are all AES. TKIP/AES means multicast is TKIP. But unicast can be AES or TKIP, which depends on the peer.) 41 Wireless: Guest Network Guest Network Enter the SSID of Guest Network, this allow families to share their home network with friends and relatives in a controlled manner without needing to expose private Wi-Fi access codes or other personal data. A guest network is a small section of an organization's computer network designed for use by temporary visitors. Besides helping to keep an organization's internal information private, guest networks also help avoid spreading any computer worms that visitors may have on their systems. 42 Wireless: WPS 43 Enable Enable the WPS feature. PIN Settings A PIN is a unique number that can be used to add the router to an existing network or to create a new network. The default PIN may be printed on the bottom of the router. For extra security, a new PIN can be generated. You can restore the default PIN at any time. Only the Administrator

("admin" account) can change or reset the PIN. Current PIN Shows the current value of the router's PIN. Reset To WPS Default Restore the default PIN of the router. Generate New PIN Create a random number that is a valid PIN. This becomes the router's PIN. You can then copy this PIN to the user interface of the registrar. 44 Wireless: Station List All the wireless clients connecting to the router will be shown here, you could monitor your network and prevent any unauthorized wireless connection easily. 45 Advanced Advanced: DMZ DMZ Setting DMZ means "Demilitarized Zone." If an application has trouble working from behind the router, you can expose one computer to the Internet and run the application on that computer. When a LAN host is configured as a DMZ host, it becomes the destination for all incoming packets that do not match some other incoming session or rule. If any other ingress rule is in place, that will be used instead of sending packets to the DMZ host; so, an active session, virtual server, active port trigger, or port forwarding rule will take priority over sending a packet to the DMZ host. (The DMZ policy resembles a default port forwarding rule that forwards every port that is not specifically sent anywhere else.) The router provides only limited firewall protection for the DMZ host. The router does not forward a TCP packet that does not match an active DMZ session, unless it is a connection establishment packet (SYN). Except for this limited protection, the DMZ host is effectively 46

"outside the firewall". Anyone considering using a DMZ host should also consider running a firewall on that DMZ host system to provide additional protection. Packets received by the DMZ host have their IP addresses translated from the WAN-side IP address of the router to the LAN-side IP address of the DMZ host. However, port numbers are not translated; so applications on the DMZ host can depend on specific port numbers. The DMZ capability is just one of several means for allowing incoming requests that might appear unsolicited to the NAT. In general, the DMZ host should be used only if there are no other alternatives, because it is much more exposed to cyberattacks than any other system on the LAN. Thought should be given to using other configurations instead: a virtual server, a port forwarding rule, or a port trigger. Virtual servers open one port for incoming sessions bound for a specific application (and also allow port redirection and the use of ALGs). Port forwarding is rather like a selective DMZ, where incoming traffic targeted at one or more ports is forwarded to a specific LAN host (thereby not exposing as many ports as a DMZ host). Port triggering is a special form of port forwarding, which is activated by outgoing traffic, and for which ports are only forwarded while the trigger is active. Few applications truly require the use of the DMZ host. Following are examples of when a DMZ host might be required:

A host needs to support several applications that might use overlapping ingress ports such that two port forwarding rules cannot be used because they would potentially be in conflict. To handle incoming connections that use a protocol other than ICMP, TCP, UDP, and IGMP

(also GRE and ESP, when these protocols are enabled by the PPTP and IPSec Enable DMZ Putting a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended as a last resort. 47 Advanced: Virtual Server Enable Specifies whether the entry will be active or inactive. IP Address The IP address of the system on your internal network that will provide the virtual service, for example 192.168.10.50. You can select a computer from the list of DHCP clients in the

"Computer Name" drop-down menu, or you can manually enter the IP address of the server computer. Protocol Select the protocol used by the service.

Destination IP The IP address of packets that will take this route. Gateway Specifies the next hop to be taken if this route is used. A gateway of 0.0.0.0 implies there is no next hop, and the IP address matched is directly connected to the router on the interface specified: LAN or WAN. Metric 50 The route metric is a value from 1 to 16 that indicates the cost of using this route. A value of 1 is the lowest cost, and 15 is the highest cost. A value of 16 indicates that the route is not reachable from this router. When trying to reach a particular destination, computers on your network will select the best route, ignoring unreachable routes. Interface Specifies the interface -- LAN or WAN -- that the IP packet must use to transit out of the router, when this route is used.
