You can use the wall mount hole on the bottom of the device to mount the device on the wall, or just put the device on the desktop. The administrator can refer to the figure below while constructing your WLAN environment. Ch 2. First Time Configuration Before Start to Configure There are two ways to configure the device, one is through web-browser, and the other is through Secure Shell CLI interface. To access the configuration interfaces, make sure you are using a computer connected to 7 the same network as the device. The default IP address of the device is 192.168.2.254, and the subnet-mask is 255.255.255.0. The device has three operation modes (Router/Bridge/WISP). In bridge mode, also known as AP Client, you can access the device by WLAN

(Wireless Local Area Network) and both wired LAN ports. And in router/WISP modes, the device can be accessed by WLAN, LAN and WAN. The default IP addresses for the device are 192.168.2.254 (for LAN), 172.1.1.1(for WAN), so you need to make sure the IP address of your PC is in the same subnet as the device, such as 192.168.2.X (for LAN), 172.1.1.X

(for WAN). Please note that the DHCP server inside the device is default to up and running. Do not have multiple DHCP servers in your network environment, otherwise it will cause abnormal situation. We also provide an auto-discovery tool which is for finding out the IP of the device. In case, youve forgot the IP of the device or the IP of the device has been changed, you can use the tool to find out the IP of the device even your PC is not in the same subnet as the device is. Knowing the Network Application The device can act as the following roles, and it supports WDS (Wireless Distribution System) function.

Access Point

WDS mode

Bridge/Router

WISP

AP Client The device provides 3 different operation modes and the wireless radio of device can act as AP/Client/WDS. The operation mode is about the communication mechanism between the wired Ethernet NIC and wireless NIC, the following is the types of operation mode. Router The wired Ethernet (WAN) port is used to connect with ADSL/Cable modem and the wireless NIC is used for your private WLAN. The other wired Ethernet (LAN) port bridges to the private WLAN. The NAT is existed 8 between WAN and WLAN/LAN and all the wireless and wired clients share the same public IP address through the WAN port to ISP. The default IP configuration for WAN port is static IP. You can access the web server of device through the default WAN IP address 172.1.1.1 and modify the setting base on your ISP requirement. Bridge The two wired Ethernet ports and wireless NIC are bridged together. Once the mode is selected, all the WAN related functions will be disabled. WISP (Wireless ISP) This mode can let you access the AP of your wireless ISP and share the same public IP address from your ISP to the PCs connecting with both the wired Ethernet ports of the device. To use this mode, first you must set the wireless radio to be client mode connecting to the AP of your ISP as the WAN connection and then you can configure the WAN IP configuration to meet your ISP requirement. The wireless radio of the device acts as the following roles. AP (Access Point) The wireless radio of device serves as communications hub for wireless clients and provides a connection to a wired LAN. AP Client This mode provides the capability to connect with the other AP using infrastructure/Ad-hoc networking types. With bridge operation mode, you can directly connect one of the wired Ethernet port to your PC and the device becomes a wireless adapter. And with WISP operation mode, you can connect one of the wired Ethernet port to a hub/switch and all the PCs connecting with hub/switch can share the same public IP address from your ISP. WDS (Wireless Distribution System) This mode combines up to 8 AP to a single wireless network; the device forwards the packets to another AP with WDS function. When this mode is selected, all the wireless clients cant survey and connect to the device. The device only allows the WDS connection. WDS+AP 9 This mode combines WDS plus AP modes, it not only allows WDS connections but also the wireless clients can survey and connect to the device. The following table shows the supporting combination of operation and wireless radio modes. AP WDS Client AP+WDS Bridge Router WISP V V V V V V X V X X V X Hereafter are some topologies of network application for your reference. Broadband Modem Internet Router Mode With WDS + AP WISP Mode Bridge Mode 10 Bridge Mode With WDS + AP Bridge Mode With AP Examples of Configuration This example demonstrates how to set up a network with different device configurations. There are 2 DHCP servers (DEV1/DEV4) in the network to control the IP configuration of 2 domains (192.168.2.x/192.168.3.x). Once the setting is done, all the PCs can visit Internet through DEV1.

AP+WDS Support both AP and WDS functions, the wireless clients and devices with WDS function supported can survey and connect to it. 28 Infrastructure:

This communication is done via the Access Point. type requires the presence of 802.11b/g Access Point. All

Ethernet AP

Ad Hoc:

AP Client #1 AP Client #2 This type provides a peer-to-peer communication between wireless stations. All the communication is done from Client to Client without any Access Point involved. Ad Hoc networking must use the same SSID and channel for establishing the wireless connection. PC #1 AP Client #1 AP Client #3 AP Client #2 PC #3 PC #2 In client mode, the device cant support the Router mode function including Firewall and WAN settings. SSID:

The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access point/bridges on a network or sub-network can use the same SSID. SSIDs are case sensitive and can contain up to 32 alphanumeric characters. Do not include spaces in your SSID. 29 Channel Number The following table is the available frequencies (in MHz) for the 2.4-GHz radio:

Channel No. Frequency Country Domain 1 2 3 4 5 6 7 8 9 10 11 12 13 14 EMEA (Europe, the Middle East and Africa). When set to Auto, the device will find the least-congested channel for use.

These settings should not be changed unless you know what effect the changes will have on your device. The default setting is optimized for the normal operation. For specific application, setting configuration will required highly attention to reach optimistic condition. Note Any unreasonable value change to default setting will reduce the throughput of the device. Authentication Type The device supports two Authentication Types Open system and Shared Key. When you select Share Key, you need to setup WEP key in Security page (See the next section). The default setting is Auto. The wireless client can associate with the device by using one of the two types. Fragment Threshold The fragmentation threshold determines the size at which packets are fragmented (sent as several pieces instead of as one block). Use a low setting in areas where communication is poor or where there is a great deal of radio interference. This function will help you to improve the network performance. 31 RTS Threshold The RTS threshold determines the packet size at which the radio issues a request to send (RTS) before sending the packet. A low RTS Threshold setting can be useful in areas where many client devices are associating with the device, or in areas where the clients are far apart and can detect only the device and not each other. You can enter a setting ranging from 0 to 2347 bytes. Beacon Interval The beacon interval is the amount of time between access point beacons in mini-seconds. The default beacon interval is 100. ACK Timing Acknowledgement Timing, is the amount of time that device wait clients response. This concept is related to EIFS (Extended Inter-Frame Space). The EIFS interval shall begin while the device is idle after detection of the erroneous frame. The EIFS is defined to provide enough time for another device to acknowledge what was, to this device, an incorrectly received frame before this device commences transmission. The default setting of ACK timing is 0. You may need to change this value due to the environment or distance. Client Expired Time The client expired time determines time interval the client need to re-associate with the device while client is idle. The default client expired time is 300 sec. MTU Size Maximum Transmission Unit, the default MTU size is 1500. The MTU setting controls the maximum Ethernet packet size your PC will send. Why a limit?

Because although larger packets can be constructed and sent, your ISP and Internet backbone routers and equipment will fragment any larger than their limit, then these parts are re-assembled by the target equipment before reading. This fragmentation and re-assembly is not optimal. You may need to change the MTU for optimal performance of your wireless LAN traffic. Data Rate The standard IEEE 802.11b/11g supports 1, 2, 5.5, 11 / 6, 9, 12, 18, 24, 36, 48 and 54 Mbps data rates. You can choose the rate that the device uses for data transmission. The default value is auto. The device will use the highest possible selected transmission rate. Broadcast SSID Broadcasting the SSID will let your wireless clients find the device automatically. If you are building a public Wireless Network, disable this function can provide better security. Every wireless stations located within the coverage of the device must connect this device by manually configure the 32 SSID in your client settings. IAPP (Inter-Access Point Protocol) This function will let Wireless Stations roam among a network environment with multiple devices. Wireless Stations are able to switch from one device to another as they move between the coverage areas. Users can have more wireless working range. An example is as the following figure. You should comply with the following instructions to roam among the wireless coverage areas. Note For implementing the roaming function, the setting MUST comply the following two items.

All the devices must be in the same subnet network and the SSID must be the same. If you use the 802.1x authentication, you need to have the user profile in these devices for the roaming station.

Block WLAN Relay (Isolate Client) The device supports isolation function. If you are building a public Wireless Network, enable this function can provide better security. The device will block packets between wireless clients (relay). All the wireless clients connected to the device cant see each other. Transmit Power The default transmit power of this device is 24dBm for CCK (802.11b) and 20dBm for OFDM (802.11g). In case of decrease the wireless distance and coverage of this device, turn down the power level for CCK and OFDM. For CCK, 4 levels are available to turn down the power from default 24dBm to 23, 22, 21,20dBm. For OFDM, 3 levels are available to turn down the power from default 20dBm to 19, 18, 17dBm. If you want to restore the wireless distance and coverage of the device, select a higher level or the default level of transmit power. 33 Configuring Wireless Security This device provides complete wireless security function include WEP, 802.1x, WPA-TKIP, WPA2-AES and WPA2-Mixed in different mode (see the Security Support Table). The default security setting of the encryption function is disabled. Choose your preferred security setting depending on what security function you need. WEP Encryption Setting Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. The WEP setting must be as same as each client in your wireless network. For more secure data transmission, you can change encryption type to WEP and click the Set WEP Key button to open the Wireless WEP Key setup page. When you decide to use the WEP encryption to secure your WLAN, please refer to the following setting of the WEP encryption:

34

64-bit WEP Encryption64-bit WEP keys are as same as the encryption method of 40-bit WEP. You can input 10 hexadecimal digits (0~9, a~f or A~F) or 5 ACSII chars. 128-bit WEP Encryption 128-bit WEP keys are as same as the encryption method of 104-bit WEP. You can input 26 hexadecimal digits

(0~9, a~f or A~F) or 10 ACSII chars.

The Default Tx Key field decides which of the four keys you want to use in your WLAN environment. WEP Encryption with 802.1x Setting The device supports external RADIUS Server that can secure networks against unauthorized access. If you use the WEP encryption, you can also use the RADIUS server to check the admission of the users. By this way every user must use a valid account before accessing the Wireless LAN and requires a RADIUS or other authentication server on the network. An example is shown as following. You should choose WEP 64 or 128 bit encryption to fit with your network environment first. Then add user accounts and the target device to the RADIUS server. In the device , you need to specify the IP addressPassword

(Shared Secret) and Port number of the target RADIUS server. 35 WPA Encryption Setting WPA feature provides a high level of assurance for end-users and administrators that their data will remain private and access to their network restricted to authorized users. You can choose the WPA encryption and select the Authentication Mode. WPA Authentication Mode This device supports two WPA modes. For personal user, you can use the Pre-shared Key to enhance your security setting. This mode requires only an access point and client station that supports WPA-PSK. For Enterprise, authentication is achieved via WPA RADIUS Server. You need a RADIUS or other authentication server on the network.

Enterprise (RADIUS):

When WPA Authentication mode is Enterprise (RADIUS), you have to add user accounts and the target device to the RADIUS Server. In the device , you need to specify the IP addressPassword (Shared Secret) and Port number of the target RADIUS server.

Pre-Share Key:

This mode requires only an access point and client station that supports WPA-PSK. The WPA-PSK settings include Key Format, Length and Value. They must be as same as each wireless client in your wireless network. When Key format is Passphrase, the key value should have 8~63 ACSII chars. When Key format is Hex, the key value should have 64 hexadecimal digits (0~9, a~f or A~F). 36 Configuring as WLAN Client Adapter This device can be configured as a wireless Ethernet adapter. In this mode, the device can connect to the other wireless stations (Ad-Hoc network type) or Access Point (Infrastructure network type) and you dont need to install any driver. Quick start to configure Step 1. In Basic Settings page, change the Mode to Client mode. And key in the SSID of the AP you want to connect then press Apply Changes button to apply the change. 1 2 3 4 5 Step 2. Check the state of connection in Status web page 37 The alternative way to configure as following:

Step 1. In Wireless Site Survey page, select one of the SSIDs you want to connect and then press Connect button to establish the link. Step 2. If the linking is established successfully. It will show the message Connect successfully. Then press OK. Step 3. Then you can check the linking information in Status page. Note 38 If the available network requires authentication and data encryption, you need to setup the authentication and encryption before step1 and all the settings must be as same as the Access Point or Station. About the detail authentication and data encryption settings, please refer the security section. Authentication Type In client mode, the device also supports two Authentication Types Open system and Shared Key. Although the default setting is Auto, not every Access Points can support Auto mode. If the authentication type on the Access Point is knew by user, we suggest to set the authentication type as same as the Access Point. Data Encryption In client mode, the device supports WEP and WPA Personal/Enterprise except WPA2 mixed mode data encryption. About the detail data encryption settings, please refer the security section. MAC Clone for Single Ethernet Client Enable/Disable Mac Clone (Single Ethernet Client) in Wireless-Basic Settings page determines whether the Ethernet Client use its own MAC address or AP-Clients MAC address to transmit data. Enable MAC Clone, the single Ethernet client can use its own MAC address. Disable MAC Clone, the single Ethernet client must to use AP-Clients MAC address. While you use this device act as AP-Client and only one host connect to this device via Ethernet, you need to check this option in this page, otherwise the other device cant recognize your host behind AP-Client. If you use hub/switch connect multi-device to this AP-Client, you should uncheck this option. 39

Extend the Remote AP (BSS) This device provides a software function to extend the AP-BSS (Basic Service Set) which is in the remote distance. When in AP, WDS, AP+WDS mode, this device can be set up to extend the remote AP BSS. This device plays two roles simultaneously, connecting to the remote AP-BSS as a WLAN client and serving as local AP-BSS and then forward packages from remote BSS to local BSS. There are two ways below to enable this function. 1. Enable this option and then select a SSID in the Table that you want. Click Apply Changes button to take effective. (Click Refresh button to make table renew) 40 1 2 3 4 6 5 Note: It only applies under APWDS and AP+WDS mode 2. Enter specific SSID in the Extended SSID field and then click Apply Changes button to take effective. 1 2 3 4 41 Ch 3. Configuring WDS Wireless Distribution System (WDS) uses wireless media to communicate with the other devices, like the Ethernet does. This function allows one or more remote LANs connect with the local LAN. To do this, you must set these devices in the same channel and set MAC address of other devices you want to communicate with in the WDS AP List and then enable the WDS. When you decide to use the WDS to extend your WLAN, please refer the following instructions for configuration.

The bridging devices by WDS must use the same radio channel.

When the WDS function is enabled, all wireless stations cant connect the device. If your network topology has a loop, you need to enable the 802.1d Spanning Tree function.

You dont need to add all MAC address of devices existed in your network to WDS AP List. WDS AP List only needs to specify the MAC address of devices you need to directly connect to.

Advanced Configurations Configuring LAN to WAN Firewall Filtering function is used to block or permit packets from LAN to WAN. The device supports three kinds of filter Port Filtering, IP Filtering and MAC Filtering. All the entries in current filter table are used to restrict or allow certain types of packets from your local network to through the device. Use of such filters can be helpful in securing or restricting your local network. Denied or Allowed list depends on your IP forwarding default policy in Route page. The IP forwarding default policy is ACCEPT. If you want block some application from LAN to WAN, you can go to Route page to select ACCEPT for IP Forwarding Default Policy. 1 2 3 4 If you want permit some application from LAN to WAN, you can go to Route page to select DROP for IP Forwarding Default Policy. 1 2 3 4 Port Filtering When you enable the Port Filtering function, you can specify a single port or port ranges in current filter table. If you select ACCEPT for the IP forwarding default policy, once the source port of outgoing packets match the port definition or within the port ranges in the table, the firewall will block those packets form LAN to WAN. 46 If you select DROP for the IP forwarding default policy, once the source port of outgoing packets match the port definition or within the port ranges in the table, the firewall will allow those packets form LAN to WAN. IP Filtering When you enable the IP Filtering function, you can specify local IP Addresses in current filter table. If you select ACCEPT for the IP forwarding default policy, once the source IP address of outgoing packets match the IP address definition in the table, the firewall will block those packets form LAN to WAN. 47 If you select DROP for the IP forwarding default policy, once the source IP address of outgoing packets match the IP address definition in the table, the firewall will allow those packets form LAN to WAN. MAC Filtering When you enable the MAC Filtering function, you can specify the MAC Addresses in current filter table. If you select ACCEPT for the IP forwarding default policy, once the source MAC Address of outgoing packets match the MAC Address definition in the table, the firewall will block those packets form LAN to WAN. 48 If you select DROP for the IP forwarding default policy, once the source MAC Address of outgoing packets match the MAC Address definition in the table, the firewall will allow those packets form LAN to WAN. NAT (Network Address Translation) NAT is the translation between public IP address and private IP address. While NAT is enabling, you can use port forwarding or DMZ to redirect your common network services. If you want to disable NAT, you can go to Management-Route page to disable it and the functions of DMZ, Port Forwarding will be disabled. 1 2 3 4 49 Configuring Port Forwarding (Virtual Server) This function allows you to automatically redirect common network services to a specific machine behind the NAT firewall. These settings are only necessary if you wish to host some sort of server like a web server or mail server on the private local network behind the device's NAT firewall. The most often used port numbers are shown in the following table. Port Number 7 21 23 25 53 79 80 110 119 161 162 5060 1723 Services ECHO FTP (File Transfer Protocol) Telnet SMTP (Simple Mail Transfer Protocol) DNS (Domain Name System) Finger HTTP (Hyper Text Transfer Protocol) POP3 (Post Protocol) NNTP (Network News Transport Protocol) SNMP (Simple Network Management Protocol) SNMP trap SIP (Session Initiation Protocol) PPTP (Point-to-Point Tunneling Protocol) About the other well-known ports, please search in http://www.iana.org/assignments/port-numbers. Multiple Servers behind NAT Example:

In this case, there are two PCs in the local network accessible for outside users. 50 Configuring DMZ A Demilitarized Zone is used to provide Internet services without sacrificing unauthorized access to its local private network. Typically, the DMZ host contains devices accessible to Internet traffic, such as Web

(HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers. So that all inbound packets will be redirected to the computer you set. It also is useful while you run some applications (ex. Internet game) that use uncertain incoming ports. Enable DMZ:
