Introducing the 802.11a/g Router This manual gives a basic introduction to 802.11a/g Wireless Router. It provides information to configure the 802.11a/g Router to operate in common applications such as connecting to the Internet. We’ll describe how to use your web browser to configure the 802.11a/g Router and to perform various management functions, e.g. upgrading the software, or viewing the system log, a task that can be useful in ongoing operations. This manual consists of the following chapters and appendixes: Chapter One, Introduction, summarizes features and capabilities of the 802.11a/g Router. Chapter Two, Installing the 802.11a/g Router, gives steps you should follow to install the 802.11a/g Router and configure your PCs. Chapter Three, Configuring the 802.11a/g Router, describes how to log in to the Web Manager, the browser screen, and steps needed to configure your 802.11a/g Router for specific applications. It gives easy-to-follow instructions for quick Internet access and provides a guide to basic 802.11a/g Router configuration. Chapter Four, Advanced Configuration, provides information on advanced router configuration. Chapter Five, Managing your 802.11a/g Router, explains other management features of the 802.11a/g Router. Chapter Six, Command Line Interface, explains the syntax and describes the function of CLI commands, which is invoked through a TELNET client. Chapter 1 Overview of the 802.11a/g Router The 802.11a/g Router is a small desktop router that sits between your local Ethernet network and a remote network (e.g., the Internet). The 802.11a/g Router contains a WAN port connecting to an external ADSL/Cable modem, a DMZ port, a four-port 10/100Mbps Ethernet switch for connection to PCs on your local wired network, and one wireless interfaces for connection to your local wireless 802.11a/b/g network supporting a data rate of up to 108 Mbps. Data comes into the 802.11a/g Router from the local wired and wireless LAN and then is “routed” to the Internet, and vice versa. 4
802.11a/g Router User’s Guide 802.11a/g Router Applications Accessing the Internet The most common use of the 802.11a/g Router is to provide shared Internet access to allow everyone on your LAN to surf the web and send/receive emails or files. The 802.11a/g Router can automatically acquire a public IP address when connecting to the Internet. In turn, it will automatically assign IP addresses to PCs (requesting DHCP client devices) on your LAN - you don’t have to apply for and assign IP addresses to PCs on your network. Accessing Servers from the Public Network If you want special servers to be accessible to remote users across the Internet (e.g., an e-mail server, an FTP server, or a web server), you can configure the 802.11a/g Router to proxy the service using its (public) IP address. It means a remote user can access the server by using the 802.11a/g Router’s IP address. Upon receiving a request, the 802.11a/g Router will re-direct the request to the actual server on your local network. Operating as an Access Point Additionally, the Wireless Router can also be configured as an Access Point, and acts as the central point of your local wireless network supporting a data rate of up to 108 Mbps. It allows client devices on your wireless network to access the Internet, to communicate with other wireless devices on your wireless network, or to communicate with devices on your wired LAN network. Since 802.11g is based on the same 2.4GHz radio band as the 802.11b technology, the 802.11a/g Router can inter-operate with existing 11Mbps 802.11b devices. Therefore you can protect your existing investment in 802.11b client cards, and migrate to the high-speed 802.11g standard as your needs grow. Alternatively, you can configure the 802.11a/g Router to provide an 802.11a WLAN environment. 5
A Security Overview More and more people are concerned about protecting your local network from the Internet. The 802.11a/g Router provides several ways to keep your network secure:  Devices on your wired or wireless network are assigned private IP addresses; therefore remote users from the Internet cannot see nor access them. This provide a firewall between your local LAN and the Internet.  The 802.11a/g Router implements IP packet filtering with SPI (Stateful Packet Inspection) capabilities, which you can use to selectively filter (discard) packets to/from the Internet.  You can selectively restrict management to remote devices. To address the growing security concern in a wireless LAN environment, different levels of security can also be enabled in the 802.11a/g Router, including:  To disable SSID broadcast so to restrict association to only client stations that are already pre-configured with the correct SSID.  To enable WEP (Wireless Encryption Protocol) encryption to implement privacy of your data  Support of Access Control List to allow you to grant/deny access to/from specified wireless stations (using MAC addresses)  Provisioning of centralized authentication through 802.1x and RADIUS Server(s).  To enable WPA (WiFi Protected Access) to assure authorized access as well as to implement privacy of your data. WPA comes with two modes: 802.1x for enterprise users and PSK (Pre-Shared Key) for SOHO users. 802.11a/g Router Features  Compliant with 802.11a, 802.11b, and 802.11g standards with roaming capability  Support of NAT for multiple users to share Internet access  IP routing (RIP1/RIP2) support  VPN (Virtual Private Network) support for PPTP/IPSec pass-through.  Support of PPPoE (multiple sessions and unnumbered IP) and PPTP client function for xDSL connections  Support of multimedia applications (NetMeeting, CUSeeMe, Quick Time, etc) pass-through.  Support of the Virtual Server function.  Support of the standard Access Point mode for connection to wireless clients  Built-in DHCP server to assign IP addresses to DHCP client devices on both wired and wireless LAN 6
802.11a/g Router User’s Guide  Multiple security measures: to enable IP packet filtering, to disable SSID broadcast, to define Access Control List, to enable WEP based encryption (up to 152 bits), to enable WPA, plus the enhanced security with 802.1x using a primary and a backup RADIUS Server  Extensive monitoring capability such as event logging, traffic/error statistics monitoring  Easy configuration and monitoring through the use of a Web-browser based GUI (only support IE6.0 or above) or SNMP commands from a remote SNMP management station  Setup Wizard for easy configuration/installation Setting Up the device The 802.11a/g Router can be managed by a local PC on either the wired or wireless LAN network. To do this, the 802.11a/g Router must have an IP address, which can be statically configured, or is dynamically obtained from a DHCP server on the LAN. For reasons to be given in Chapter 3, static IP address assignment is much preferred. 7
Installing the 802.11a/g Router This section describes the installation procedure for your 802.11a/g Router. It starts with a summary of the content of the package you have purchased, followed by steps of how to connect and power up your 802.11a/g Router. Finally, it describes how to configure a Windows PC to communicate with your 802.11a/g Router. Chapter 2 What’s in the Box?

802.11a/g Router User’s Guide Connecting the Cables Follow these steps to install your 802.11a/g Router: Step 1 Connect ADSL/Cable modem to the Wireless Router WAN port using CAT5 UTP LAN cable. Step 2 Connect a PC/Workstation to one of the LAN ports of the Wireless Router, such as port 1 or port 2. Step 3 Connect the DC adapter to the Wireless Router and an electrical outlet. High Level Configuration Steps Required for the 802.11a/g Router This section describes configuration required for the 802.11a/g Router before it can work properly in your network. Normally, devices on a LAN (except for servers) are configured to obtain their IP addresses automatically. Depending on whether there is a separate DHCP server available in your LAN environment network, thus to determine if you need to enable the built-in DHCP server in the Wireless Router. The following configuration step assumes that the router’s built-in DHCPS will be used. Additionally, since you need to perform various configuration changes to the 802.11a/g Router, including the SSID, Channel number, the WEP key, …, etc., it is necessary to associate a fixed IP address with the 802.11a/g Router, which is why the 802.11a/g Router will be shipped with a factory default private IP address of 192.168.1.1 (and a network mask of 255.255.255.0). 11
Setting up a Windows PC or wireless client as DHCP clients The following will give detailed steps of how to configure a PC or a wireless client to “obtain IP addresses automatically”. For other types of configuration, please refer to the corresponding user manual. For the case of using a LAN attached PC, the PC must have an Ethernet interface installed properly, be connected to the 802.11a/g Router either directly or through an external LAN switch, and have TCP/IP installed and configured to obtain an IP address automatically from a DHCP server in the network. For the case of using a wireless client, the client must also have a wireless interface installed properly, be physically within the radio range of the 802.11a/g Router, and have TCP/IP installed and configured to obtain an IP address automatically from a DHCP server in the network. Configuring a PC running MS-Windows 95/98/Me: 1. Click the Start Button, and select Settings. 2. Click the Control Panel. The Win95/98/Me Control Panel will appear. 3. Open the Network setup window by double-clicking the Network icon. 4. Check your list of Network items. If TCP/IP is already installed, proceed to step 5. Otherwise: (You may need your Windows CD to complete the installation of TCP/IP.)  Click the ADD button.  In the Network Component Type dialog box, select Protocol.  In the Select Network Protocol dialog box, select Microsoft.  In the Network Protocols area of the same dialog box, select TCP/IP and click OK. 5. With TCP/IP installed, select TCP/IP from the list of Network Components. 6. In the TCP/IP window, check each of the tabs and verify the following settings: Bindings: Select Client for Microsoft Networks and Files and printer sharing for Microsoft Networks Gateway: All fields are blank. DNS Configuration: Select Disable DNS. WINS Configuration: Select Use DHCP for WINS Resolution. IP address: Select the Obtain IP address automatically radio button. 7. Reboot the PC. Configuring a PC running MS-Windows XP/2000: 1. Click the Start button, and choose Control Panel (in Classic View). 2. In the Control Panel, double-click Network Connections. 3. Double-click Local Area Connection. 4. In the LAN Area Connection Status window, select Internet Protocol (TCP/IP) and click Properties. 5. Select the Obtain an IP address automatically and the Obtain DNS server address automatically radio buttons. 12
802.11a/g Router User’s Guide 6. Click OK to finish the configuration. Confirming your PC’s IP Configuration: There are two tools useful for finding out a computer's IP address and default gateway: WINIPCFG (for Windows 95/98/Me) Select the Start button, and choose Run. Type winipcfg, and a window will appear listing the IP configuration. You can also type winipcfg in the MS-DOS prompt. The procedure required to set a static IP address is not too much different from the procedure required to set to “obtain IP addresses dynamically” - except that at the end of step 7, instead of selecting “obtain IP addresses dynamically, you should specify the IP address explicitly. Connecting More Devices Through A Switch/Hub To The 802.11a/g Router The Wireless Router provides four LAN ports to allow up to four PCs or Workstations to be connected to it directly. If you want to connect more devices, you can connect an external hub or switch to any of the LAN ports using a LAN cable. 13
Basic Configuration of the 802.11a/g Router This section contains basic configuration procedure for the 802.11a/g Router. It describes how to set up the 802.11a/g Router for Internet Access operation, and how to set up the LAN configuration. The 802.11a/g Router is designed so that all basic configuration may be easily invoked through the a standard Web browser such as Internet Explorer. Currently only the Internet Explorer 6.0 (or above) is supported. To access the WLAN 11a/g Router’s management interface for the first time, enter the default IP address of the WLAN 11a/g Router in your Web browser http://192.168.1.1/. 14Note: The IP address of your PC must be in the same IP subnet as the 802.11a/g Router. It is preferred that you configure the PC to obtain an IP address automatically from the 802.11a/g Router. The Home Page of the 802.11a/g Router screen will appear, with its main menu displayed on the screen, showing the following top-level choices: Setup Wizard, Device Status, System Tools, Advanced Settings, and Help. Selecting any will allow you to navigate to other configuration menus. Logging On Chapter 3
802.11a/g Router User’s Guide When you attempt to access a configuration screen from the browser menu, an administrator login screen will appear, prompting you to enter your password to log on. Once you are logged in, you will not be asked to log in again unless your “session” expires such as due to inactivity timeout. If you are logging in for the first time after you received your 802.11a/g Router, you should use the factory default password, “password” to log in. (You should change it as soon as after you log in.) Characters you type (as your password) will be echoed back as a string of asterisks (“*”) for security reasons. After you enter the password, clicking the LOG ON button will begin the password verification process and, if successful, your configuration session can begin. Note: Should there be no settings or access on the web management screen, system will logout automatically in 10 minutes. Setup Wizard The Setup Wizard will guide you through a series of configuration screens to set up the basic configuration of your 802.11a/g Router. At the end of the Setup Wizard screens, you should press the “finish” button, and all your configuration modifications will take effect. SETTING UP YOUR LOCAL TIME ZONE AND DATE/TIME After logging in, the Time Settings page appears. The router time will first be set to the local time of the PC (on which the browser is running). If this time is not correct, modify the appropriate fields as necessary, and then click “NEXT”. Since the device does not have a real time clock on it, the system time needs to be set every time the device is booted up. You can enable the NTP (Network Time Protocol) function, which will set the system time periodically to the time queried from the NTP server configured. You can specify the NTP server to be queried either by selecting a well-known server or by entering the IP address of the server. The 802.11a/g Router will query the configured NTP server for the current time periodically according to the NTP request interval configured. 15
CONFIGURE THE ISP PROFILE In the following configuration screen, as with the usual convention, radio buttons are used to make a selection when only one out of multiple mutually exclusive choices can be selected, while square check boxes can be used to select multiple non-mutually-exclusive choices. When configuring the device for Internet access, decide which one of the following multiple choices to select (through radio buttons): 1. You can use a static IP address provided by your ISP to connect to the Internet. In this case, you need to configure the following information: • IP Address Assigned by your ISP: the IP address of the WAN interface of your router. • IP Subnet Mask: the IP subnet mask of the WAN interface of your router. • ISP Gateway IP Address: the IP address of your ISP’s Gateway. • DNS IP Address: the IP address of the DNS server. 2. You use the user name and password assigned by your ISP to connect to the Internet (required for the underlying PPPoE protocol). In this case, you need to configure the following information: • User name: the username of your ISP account. • Password: the password of your ISP account. 16
802.11a/g Router User’s Guide • Service Name: the service name of your ISP account • Connection Type: There are 3 options for this option. Always on: the connection is always on no matter there is traffic or not. If the connection is lost (e.g. the PPPoE server is down or the ADSL/Cable line is disconnected), the connection will be brought up right after the connection is recovered. Demand Dialing: the connection will be brought up only when there is traffic. That is, it requires an outgoing packet to trigger the connection. Manually: the connection will not be brought up until you manually connect it at the WAN Status page (described in How To View The Device Status section). • MTU/MRU: This is to set the values of MTU (Maximum Transmit Unit) and MRU (Maximum Receive Unit) that is used between the 802.11 a/g Router and the ISP device at the other side. Users are not encouraged to change these values unless you know what you are doing. • Session Type: There are 3 options for this setting. Normal: This option only supports one PPPoE session. Unnumbered Link: This option can let your LAN be a public IP subnet. That is, PC’s on the LAN can be configured with public IP addresses provided by your ISP. You can put your own servers on the LAN, and then people on the Internet can access these servers. The source IP address of the traffic from these PC’s to the Internet is not modified (i.e. NAT is not applied) either. If you still want to keep a private LAN, you can check the Maintain Private LAN setting and enter the IP Address and IP Subnet Mask of your private LAN. If you do not keep a private LAN, the “Device IP Settings” menu at the left side will disappear. Multiple PPPoE: You can define more than one PPPoE sessions by using this option. The primary session is configured at the ISP Settings page, and other sessions are configured at the Multiple PPPoE page. 3. You use DHCP to connect to the Internet (most likely through a cable modem connection). In this case, your ISP may require you to configure the Host Computer Name: • Host Name: The Host Name provided by your ISP. 4. You use PPTP to connect to the Internet. In this case, your ISP requires you to configure PPTP's tunnel IP address, the username, and password. In this case, configure the static IP address as in the above and then configure the following information: • PPTP Local IP Address: the IP address on the local side of the PPTP tunnel provided by your ISP. • PPTP IP Netmask: the Netmask on the local side of the PPTP tunnel provided by your ISP. • PPTP Remote IP Address: the IP address of the remote side of the PPTP tunnel provided by your ISP. • User Name: the username of your ISP account. • Password: the password of your ISP account. 17
• Idle time: The Idle Timeout is the number of seconds of "inactivity" before the PPTP connection is taken down. Its value should be between 0 to 60 minutes, with 5 (minutes) being the default value, and 0 meaning the connection will never time out. Cloned MAC Address: Some ISPs expect a PC to be connected to their service, and use the MAC address of this PC’s LAN card for identification purposes. By checking the following “Cloned MAC address” square check box, your 802.11a/g Router allows a MAC address to be configured and “cloned” in the router to simulate a PC. If the device is a PC based on WIN 95/98/Me, you can run winipcfg to find out the MAC Address of its LAN card. If the device is a PC based on WIN 2000/NT/XP, you need to run "ipconfig/all" to find out the MAC address of its LAN card. 18
802.11a/g Router User’s Guide 19
MULTIPLE PPPOE SETTINGS If you have selected PPPoE with Multiple PPPoE type at the ISP Settings page, you will see the Multiple PPPoE settings page where you can add more PPPoE sessions. For each PPPoE session, you have to assign a mnemonic name and configure similar settings as in the primary session. In addition, you can configure LAN Type and Traffic Pattern in order to use an added session. LAN Type: If you enable LAN Type, you can have another subnet on your LAN environment. Some ISP provides Group Access function that gives you a subnet to assign on your LAN environment, and ISP will make all such subnets belonging to the same Group connected together. A PC on such subnets can reach other PCs on the Internet within the same Group through the session configured without NAT; it also can do the normal Internet access through the primary PPPoE session. Traffic Pattern: You have to configure traffic pattern(s) in order to use PPPoE sessions other than the primary session. Any outgoing packet matching one of the traffic pattern configured will be sent out using the corresponding PPPoE session. There are four types of traffic patterns that you can use. After you checked a traffic pattern and clicked the APPLY button you have to configure the details by selecting the item in the Session Table and click the EDIT TRAFFIC PATTERN button. IP Address Range/Network: Packets with destination IP address within the range or network configured are matched. Port Range: TCP/UDP packets with the source or destination port in the configured range are matched. Keyword: IP packets with a payload containing a string matching the configured keyword are matched. NetBIOS: NetBIOS packets are matched. Multiple PPPoE usage can be well illustrated by the following diagram. 20
802.11a/g Router User’s Guide 21
DEVICE IP SETTINGS The Device IP setting screen allows you to configure the IP address and subnet mask of your 802.11a/g Router: you can configure a static IP address and a subnet mask, or configure it to obtain an IP address and a subnet mask automatically from a DHCP server on the local network. If you choose to assign a static IP address manually, check the button that says, “Assign static IP to this device” and then fill in the following fields IP Address and IP Subnet Mask: These values default to 192.168.1.1 and 255.255.255.0, respectively. This IP address can be modified if necessary, to either a different address in this same subnet or to an address in a different subnet. When you modify it, if the DHCP server function of your 802.11a/g Router is enabled, the pool of IP addresses it will use for assignment purposes will also be automatcailly adjusted accordingly. For example, if the default IP address is used, the IP address pool for assignment consists of addresses from 192.168.1.2 to 192.168.1.254. However, please do not change the default IP address unless you know exactly what you want to achieve. Then you should press Next to get to the next screen. If you choose to use an external DHCP Server to automatically assign an IP address to your 802.11a/g Router, check the button that says, “Use the DHCP protocol to automatically get the IP address for this device”, and then press Next to the next screen. When an IP address is dynamically assigned to the router, its value can change depending on the IP address assignment policy used by the DHCP server in the network. Since you need to use an IP address to control and manage your 802.11a/g Router, without the knowledge of its IP address, in 22
802.11a/g Router User’s Guide order to access it, you will need to use UPnP (Universal Plug and Play) or other management tools that do not depend on a fixed IP address. It is strongly recommended that you select the manual static IP address. CONFIGURE YOUR WIRELESS LAN CONNECTION In the following configuration screen, you can configure wireless related parameters of your 802.11a/g Router: Network Name (SSID): The SSID is the network name used to identify a wireless network. The SSID must be the same for all devices in the wireless network. Several Routers on a network can have the same SSID. The SSID can be up to 32 characters long. This SSID is used for both radios (i.e. 802.11a and 802.11 b/g). Disable SSID Broadcasting: An access point periodically broadcasts its SSID, along with other information, which allows client stations to learn its existence while searching for Routers in the wireless network. Select Disable if you do not want the device to broadcast the SSID. Regulatory Domain: This place shows the regulatory domain where the device is running. This field cannot be changed by regulation. WLAN standard: Here you can set the configuration for the radio. Mode: You can select the radio to run the 802.11b/g (mix mode – allowing both 802.11b and 802.11g to co-exist), 802.11g only, 802.11g turbo, super g without turbo, super g with dynamic turbo, super g with static turbo, 802.11a, 802.11a turbo, super a without turbo, super a with dynamic turbo, or super a with static turbo protocol (the turbo mode is only applied where the regulation allows). Channel: Select the channel from the available list to match your network settings. All devices in the wireless network must use the same channel and share the total bandwidth available. Note: The available channels are different from country to country and for different WLAN mode. Security Policy: You can select different security policy to provide association authentication and/or data encryption. 23
WEP You can use WEP encryption to protect your data when you are transmitting data in the wireless network. There are 3 types of keys: 64 (WEP64), 128 (WEP128), and 152 (WEP152) bits. You can configure up to 4 keys using either ASCII or Hexadecimal format. Key Settings: For WEP64 and WEP128, you can enter a “Passphrase” (a key of up to 32 alphanumerical characters), choose 64-bit, and press the Generate button to generate four WEP64 keys in the entries below, or choose 128-bit, and press the Generate button to generate one WEP128 key in the first entry. Alternatively, and for WEP152, you can manually configure each of them. When you manually configure a key, the length for a WEP64 key must be equal to 5, for a WEP128 key it must be equal to 13, and for a WEP152 key it must be equal to 16. Once you enable the WEP function, please make sure that exactly the same WEP key is configured in both the Wireless Router and client stations. You can define a key using ASCII or hex characters. A WEP128 ASCII key looks like "An ASCII key!" (13 characters), while a WEP64 hex key looks like "44-12-24-A8-B2" (5 bytes) and “11-22-33-44-55-66-77-88-99-00-A3-BB-2C” as WEP128 hex key. Each set of hexadecimal numbers should be separated by “-“(dash). 24
802.11a/g Router User’s Guide Key Index: You have to specify which of the four keys will be active. Please note that some Wireless Client Cards allow hexadecimal characters only. 802.1x IEEE 802.1x is an IEEE standard which is based on a framework that involves stations to be authenticated (called Supplicant), an authentication server (a RADIUS Server) that provides authentication services, and an authenticator that provides necessary translation and mediating functions between the authentication server and stations to be authenticated, in this case your 802.11a/g Router. During EAP authentication, the 802.11a/g Router relays authentication messages between the RADIUS server and clients being authenticated. 802.1x allows users to leverage a RADIUS server to do association authentications. You can also enable dynamic WEP keys (64, 128, 152-bit) to have data encryption. Then you do not have to enter the WEP key manually because it will be generated automatically and dynamically. Note: After you have finished the configuration wizard, you have to configure the Radius Settings in Advanced Settings in order to make the 802.1x function work. WPA-PSK Wi-Fi Protected Access (WPA) with Pre-Shared Key (PSK) provides better security than WEP keys. It does not require a RADIUS server in order to provide association authentication, but you do have to 25
enter a shared key for the authentication purpose. The encryption key is generated automatically and dynamically. Pre-shared Key: This is an ASCII string with 8 to 63 characters. Please make sure that the 802.11a/g Router and the wireless client stations use the same key. Encryption Type: There are two encryption types TKIP and CCMP (AES). While CCMP provides better security than TKIP, some wireless client stations may not be equipped with the hardware to support it. You can select Both to allow TKIP clients and CCMP clients to connect to the Access Point at the same time. Group Rekey Interval: A group key is used for multicast/broadcast data, and the rekey interval is time period that the system will change the group key periodically. The shorter the interval is, the better the security is. 60 seconds is a reasonable time, and it is used by default. WPA Wi-Fi Protected Access (WPA) requires a RADIUS server available in order to do authentication (same as 802.1x), thus there is no shared key required. The Encryption Type and Group Rekey Interval settings are same as WPA-PSK. FINISH SETUP WIZARD AND SAVE YOUR SETTINGS After stepping through the Wizard’s pages, you can press the FINISH button for your modification to take effect. This will also cause your new settings to be saved into your system permanently. 26
802.11a/g Router User’s Guide Alternatively, you can also click the “Back” button to go back to previous configuration screens for more changes. Note: If you change the router’s IP address to a different IP network address space, as soon as you click on FINISH you will no longer be able to communicate with your 802.11a/g Router. You need to change your IP address and then re-boot your computer in order to resume the communication. 27
Chapter 4 Advanced Settings This section contains advanced setting procedures for the 802.11a/g Router. It describes modifications that normally you may not need for basic system operation. One exception is changing your password: it is highly recommended that you change the default factory setting as soon as you start to use your 802.11a/g Router. Operational Mode Before you start to use the device, you need to select the operational mode to be wireless AP only or both Internet gateway and wireless AP:  Wireless Access Point only: When this is selected, the router operates in the AP-only Mode, and connects Wireless Client Users to the Ethernet (WAN).  Internet Gateway + Wireless Access Point: When this is selected, the router will function as an Internet access sharing device as well as a wireless AP.  Internet Gateway + Wireless Access Point with WDS Support: When this is selected, the router will function as an Internet access sharing device as well as a wireless AP, plus the mode to participate in the wireless distribution system. This could broaden the WLAN scope across several AP’s. You should add all the WDS participants' MAC addresses with a mnemonic name in addition. When adding a WDS participant, you also have to select the radio (i.e. Radio1 or Radio2) that the participant will be connected with. 28
802.11a/g Router User’s Guide Password Settings Your 802.11a/g Router comes with a default factory password of “password”. After you start using the router, you should change the default password. To change the password, press the Password Settings button to enter the Password Settings screen, enter the current password followed by the new password twice. The entered characters will appear as asterisks. If you forgot the password, the only way to recover it is to return the device to its default state as shipped from the factory. To restore the password to the default password, please refer to the section, "What if I forgot the Password?" in the user manual. 29
System Management Clicking the System Management button allows system related parameters to be configured for the 802.11a/g Router. Remote Management: The remote management feature allows you to manage your 802.11a/g Router remotely through the use of an HTTP browser. The system allows you to (1) allow remote management from all WAN IP addresses, to (2) allow remote management from up to two WAN IP addresses, or to (3) disallow remote management from any WAN IP addresses. System Administration: The router allows you to designate special port numbers other than the standard 80 for http for remote management. It also allows you to specify the duration of idle time (inactivity) before a web browser session times out. The default time-out value is 10 minutes. UPnP: The router's Universal Plug and Play (UPnP) feature allows a Windows XP/ME PC to discover the router and automatically show an icon in the task bar on the screen. You can double-click the icon to access the router directly (without having to specify its IP address). Disable Ping: "Ping" is a utility for testing the connectivity. Response to a ping can be disabled, such as when you do not want the router to be accessed (e.g., attacked) from the Internet. Bridge: You can enable/disable the 802.1d STP (Spanning Tree Protocol) function on the bridge of WLAN and Ethernet (i.e. the LAN interface). Enable this function can detect loops in your LAN environment and then protect the LAN from being saturated with infinite loop traffic. 30
802.11a/g Router User’s Guide Syslog: Syslog is an IETF (Internet Engineering Task Force - the Internet standards body)-conformant standard for logging system events (RFC-3164). When the 802.11a/g Router encounters 31
an error or warning condition (e.g., a log-in attempt with an invalid password), it will create a log in the system log table. To be able to remotely view such system log events, you need to check the Enable Syslog box, configure the IP address of a PC where a Syslog daemon is running in the background. When doing so, the 802.11a/g Router will send logged events over the network to the PC for future viewing. Syslog server IP address: The IP address of the PC where the Syslog daemon is running. Email Log: If the Email Log function is enabled, every system log message will be sent to the configured email address through the configured mail server. Mail Server: the mail server domain name that you use to send syslog emails. Email Address: the email address that syslog emails will be sent to. SNMP Settings This screen allows you to configure SNMP parameters including the system name, the location and contact information. Additionally, you can configure the 802.11a/g Router to send SNMP Traps to remote SNMP management stations. Traps are unsolicited alert messages that 802.11g Router sends to remote management stations. 32
802.11a/g Router User’s Guide System Name: A name that you assign to your 802.11a/g Router. It is an alphanumeric string of up to 30 characters. System Location: Description of where your 802.11a/g Router is physically located. It is an alphanumeric string of up to 60 characters. System Contact: Contact information for the system administrator responsible for managing your 802.11a/g Router. It is an alphanumeric string of up to 60 characters. Community String For Read: If you intend the router to be managed from a remote SNMP management station, you need to configure a read-only “community string” for read-only operation. The community string is an alphanumeric string of up to 15 characters. 33
Community String For Write: For read-write operation, you need to configure a write “community string”. A trap manager is a remote SNMP management station where special SNMP trap messages are generated (by the router) and sent to in the network. You can define trap managers in the system. You can add a trap manager by entering a name, an IP address, followed by pressing the ADD button. You can delete a trap manager by selecting the corresponding entry and press the DELETE SELECTED button. You enable a trap manager by checking the Enable box in the corresponding entry or disable the trap manager by un-checking the Enable box. DHCP Server Settings The DHCP server option allows the 802.11a/g Router to assign IP addresses to DHCP client devices on your wired or wireless LAN to obtain IP addresses automatically. If you want the Router to act as a DHCP server and assign private IP addresses to requesting DHCP clients on the LAN, you need to check the Enable DHCP Server box. You can select one of the following two ways to assign IP addresses: Assigns IP addresses to wired or wireless clients from the following range: When IP addresses are assigned to a requesting DHCP client, after the “lease time”, the client is expected to renew the lease. Its default value is 10080 minutes. The from and to range of IP addresses to be assigned to requesting DHCP clients can be configured manually, with the default being 2 to 254. After you enter the information, you should press APPLY. Assigns the following IP address to the client with the following MAC address: You can also specify the IP address to be assigned to a device with a pre-configured MAC address. You can add such a mapping by entering a MAC address, and the IP address to be assigned, followed by pressing the ADD button. Up to 20 mappings can be added. You can delete a mapping by selecting the corresponding entry and press the DELETE SELECTED button. DHCP Table: Press this button will cause the screen to jump to DHCP client table page. 34
802.11a/g Router User’s Guide Multiple DMZ The router supports one hardware DMZ port, multiple software DMZ ports, plus one default DMZ port. The hardware DMZ is implemented through the hardware: the router has a separate hardware Ethernet port, to which multiple devices with public IP addresses assigned by the ISP can be connected. Incoming data for these devices from the Internet will be sent by the router to the hardware Ethernet port directly. No configuration would be required. Both the default and multiple DMZ ports are implemented through software. When the router receives incoming data from the Internet, it will search through an internal address translation table to perform address translation function. If a match can be found, the data will be forwarded to the corresponding device in your local LAN, otherwise the data will be dropped or forwarded to the default DMZ if it is configured. 35
An additional feature is to allow devices with WAN IP addresses to be used by the Internet users to access private devices in your local LAN. In this case, you need to configure the mapping between the WAN IP address and the private IP address. To add the default DMZ, you need to select “Default DMZ” and enter the local DMZ IP address, followed by pressing the ADD button. To add a device for multiple DMZ, first select “Multiple DMZ”, add a mnemonic name, a public WAN IP address, and the local DMZ IP address on the LAN, followed by pressing the ADD button. You can delete a DMZ entry by selecting the corresponding entry and press the DELETE SELECTED button. Virtual Server Settings A Virtual Server is a server built on a single or a cluster of real servers. A DMZ server is a term commonly used to describe the default Virtual Server - the router will redirect all traffic from the Internet without a valid port address mapping to this device. An HTTP server with a private IP 36
802.11a/g Router User’s Guide address on the LAN allows access from the Internet by mapping a special port to the HTTP server. In this case, the HTTP service will be mapped to a special port of the Router. You can add a virtual server mapping by (1) selecting the service name (such as HTTP, FTP, TELNET, SMTP, POP3, CUSTOM), (2) enter the public port number to be used (either a single port number or a range), (3) enter the local IP address of the server on your LAN, (4) enter its local port number to map to (if is public port number a range, local port number is not allowed to specify), (5) followed by pressing the ADD button. You can delete a mapping by selecting the corresponding entry and press the DELETE SELECTED button. Note: Virtual Server Setting and IP Filtering may affect with each other. Special Applications Special applications such as the Microsoft instant messaging or some Internet games are getting to be increasingly popular. These applications usually work in the following manner: 37
A client can start an Internet game by first registering with a game server on the Internet. Other clients can, using the corresponding protocol, join the game by checking with the server and deciding if to join the game. A client can "leave" the game at any time. If the initiating client is behind your router, you need to add the application by performing the following configuration: Select an application: Select an application that you want to add to the supported list. You should choose "Other" if your application is not explicitly shown in the list. Name: You can provide a mnemonic name. Trigger Port: You need to specify, based on instructions provided by your application’s user manual, the (UDP/TCP) port number in the router that the initiating client uses to start an Internet game. Trigger Type: Select UDP, TCP, or both for the trigger port. Opened ports: You need to specify the port numbers in the router that joining clients can use to communicate with the initiating client, again based on instructions provided by your application user manual. Public Type: Select UDP, TCP, or both for the Opened ports. After you finish the above, you press the ADD button to add an entry to the table. You can delete an entry by selecting the corresponding entry and press the DELETE SELECTED button. 38
802.11a/g Router User’s Guide MAC Filtering Settings The 802.11a/g Router allows you to define a list of MAC addresses. One of three mutually exclusive rules can be selected to forward/filter data packets based on these MAC addresses.  Disable MAC address control list: When this radio button is selected, no MAC address filtering will be performed.  Enable GRANT address control list: When this radio button is selected, only packets received from the wireless LAN interface with the configured MAC addresses will be allowed/forwarded. 39
 Enable DENY address control list: When this radio button is selected, only packets received from the wireless LAN interface with the configured MAC addresses will be denied/filtered. Once a choice is made, the choice applies to all filtering rules. To add a filtering rule, configure the following: Mnemonic Name: the name to identify the filter MAC Address: the MAC address for grant or deny. After you finish the above, you press the ADD button to add the entry to the table. There are up to 32 MAC filtering rules could be configured. You can delete an entry by selecting the corresponding entry and press the DELETE SELECTED button. IP Filtering Settings Three mutually exclusive rules can be defined to forward/filter IP packets based on their IP address and/or port numbers. 40
802.11a/g Router User’s Guide  Disable IP filtering: If this is selected, the IP filtering feature is disabled. No IP filtering will be performed.  GRANT IP access: When this is elected, packets received from/transmitted to WAN with specified (source or destination) IP addresses will be allowed/forwarded.  DENY IP access: Packets received from/transmitted to WAN with the specified IP addresses will be denied/filtered. Once a choice is made, the choice applies to all filtering rules. To define/add an IP filtering rule, enter the following information • Name: The name of the filter • IP Protocol: TCP or UDP • Apply to: You need to select whether the filtering rule should apply to packets outbound for the Internet or inbound from the Internet. • Source IP address: you can select Any, Single IP, or a Network (of source IP addresses). • Source Port: you can select Any, Single, or a Range of port numbers. • Destination IP address: Any, Single IP, or a Network (of destination IP addresses). • Destination Port: you can select Any, Single, or a Range of port numbers. After you finish the above, you press the ADD button to add the entry to the table. There are up to 32 IP filtering rules could be configured. You can delete an entry by selecting the corresponding entry and press the DELETE SELECTED button. Please Note that IP filtering is a sophisticated feature that can severely impact your Router operation. Please be sure that you fully understand it before you use this feature. If you make any mistakes, it can produce dramatic and potentially undesirable results. 41

802.11a/g Router User’s Guide IP Routing Settings Dynamic Routing: Enable gateway to exchange the routing table dynamically with other routing devices. Currently you can select either RIP or OSPF as the routing protocol. RIP: When RIP is selected, you can choose to run RIP1 or RIP2 with active mode (Send/Receive) or passive mode (Receive Only). With active mode, the 802.11a/g Router will send out RIP packets describing its routing database, and it will also update the database according to the received RIP packets from other routing devices. With passive mode, the 802.11a/g Router will only update the database according to the RIP packets received, it will not send out any RIP packets. OSPF: When OSPF is selected. You can select the interface (LAN and/or WAN) to run OSPF. For each interface where OSPF is enabled, you have to configure the Area that the interface belongs to by specifying the Area ID, the Area type (either Regular or Stub), and the priority of the 802.11a/g Router on the segment the interface belongs to. Also, for the segment that an OSPF enabled interface, you have to configure the Hello interval and Dead interval on the segment, the Cost for transmitting a packet on the segment, and the Authentication method used on the segment. If an authentication method is used, either Simple Password or MD5, a shared secret has to be configured for the authentication purpose. OSPF Summarization can be enabled to consolidate multiple routes into one single advertisement and hence reduce the routing database make routing simpler and faster. When this function is enabled, it will only be effective when the 802.11a/g Router is an ABR (Area Border Rouer), that is, at least two OSPF enabled interface are configured with different Area IDs. For each summarization entry, you have to enter the Area ID such that routes from the Area falling into the specified subnet (IP address/Netmask) will be summarized into a single route to the specified subnet and it is the single route instead of the individual route to be injected into other Areas. Static Routing: If you have routers on your LAN or WAN, you can configure static routes on the 802.11a/g Router to route network traffic to a specific, predefined destination. The 802.11a/g Router routes packets based only on the packet's destination not on the source of a packet. Static routes must be defined if the LAN or WAN are segmented into subnets. For example, a subnet can be created to isolate a section of a company, such as finance, from traffic on the rest of the LAN or WAN. Static Routes are configured when network traffic is directed to a specific destination on the network whether it is the LAN or WAN. For instance, you can configure the 802.11a/g Router to route traffic destined to a particular network to a specific router on the LAN or WAN using the following steps: 1. Enter the IP address of the destination network in the Destination Network field. 2. Enter the subnet in the Subnet Mask field. 3. Enter the IP address of the specific router in the Gateway IP Address field. 4. Select LAN or WAN, where is the specific router is, from the Interface menu. 43
5. Enter the metric (cost) for sending a packet following this route. 6. Click Add. IP Routing Table: The Routing Table shows a list of destinations that the IP software maintains on each host and router. The destination network IP address, subnet mask, gateway address, and the corresponding interface are displayed. Note! The 802.11a/g Router can support up to 128 static route entries. 44
802.11a/g Router User’s Guide 45
Wireless Settings You can use this screen to configure various parameters of your 802.11a/g Router. Beacon Interval: The 802.11a/g Router broadcasts beacon frames regularly to announce its existence. The beacon Interval specifies how often beacon frames are transmitted - in time unit of milliseconds. Its default value is 100; a valid value should be between 20 and 1000. RTS Threshold: RTS/CTS frames are used to gain control of the medium for transmission. Any unicast (data or control) frames larger than the specified RTS threshold must be transmitted following the RTS/CTS handshake exchange mechanism. The RTS threshold should have a value between 0 and 2347 bytes, with a default value of 2347. A value of zero activates the RTS/CTS handshake before every transmission. It is recommended that this value does not deviate from the default too much. Fragmentation: When the size of a unicast frame exceeds the fragmentation threshold, the frame will be fragmented before transmission. The threshold should have a value of 256-2346 bytes, with a default value of 2346. If you experience a high packet error rate, you should slightly decrease the Fragmentation Threshold. DTIM Interval: The 802.11a/g Router buffers packets for stations that operate in the power-saving mode. A Delivery Traffic Indication Message (DTIM) contains information on which power-conserving stations have packets waiting to be received. The DTIM interval specifies how often beacon frames should contain DTIMs. It should have a value between 1 and 255, with a default value of 3. User Limitation: You can limit the number of stations that can get associated with the 802.11 a/g Router; the purpose is to assure the WLAN service quality provided. Enable privacy separator: To increase the security and prevent any two WLAN connected device from accessing each other, you can check this option. 46
802.11a/g Router User’s Guide RADIUS Settings RADIUS (Remote Access Dial-In User Service) servers provide centralized authentication services to wireless clients. For the WLAN security policy 802.1x and WPA, a RADIUS server is required for the authentication purpose. Users can use the built-in RADIUS server and/or configure up to two RADIUS servers can be used, one acting as a primary, and the other as a backup. Use Built-in Radius Server: The built-in RADIUS server can be used for the 802.1x and WPA security policies. When this option is checked, the primary/secondary RADIUS server would be used only if the built-in RADIUS server is not enabled. The built-in RADIUS server can be enabled at the “Radius Server Settings" page. However, when you check the “Enable Built-in Certificate Authority” option at the “Radius Server Settings" page, this option “Use Built-in Radius Server” will be checked automatically. Enable MAC Address Access Control: MAC address filtering requires a MAC address filter table to be created in either the 802.11a/g Router and/or the RADIUS server. During the 802.11 authentication phase, the MAC address filter table is searched for a match against the wireless client’s MAC address to determine whether the station is to be allowed or denied to access the network. To leverage a RADIUS server for MAC address access control, check the box here. To use this feature, you have to configure the MAC addresses of authorized WLAN clients as the user name and password in the RADIUS server you use, and the RADIUS server should support PAP authentication. Enable Primary Server: To configure the primary server, check the “Enable Primary Server” box, and configure the following parameters: Server IP: The IP address of the RADIUS server Port Number: The port number your RADIUS server uses for authentication. The default setting is 1812. Shared Secret: This is used by your RADIUS server in the Shared Secret field in RADIUS protocol messages. The shared secret configured in the 802.11a/g Router must match the shared secret configured in the RADIUS server. The shared secret can contain up to 64 alphanumeric characters. Enable Secondary Server: To configure the secondary server, check the “Enable Secondary Server” box, and configure the same parameters as for the primary server. RADIUS Server Retry Times: The number of times the 802.11a/g Router should attempt to contact a RADIUS server before giving up and try the next RADIUS server. The contact sequence is Built-in server (if used)  Primary server (if enabled)  Secondary server (if enabled). RADIUS Server Reattempt Period: After failed to contact the first RADIUS server (the built-in server, or the Primary server if the built-in server is not used), the 802.11a/g Router will re-attempt to contact the first server every this mount of minutes even if the server being used is still working. 47
Radius Server Settings The 802.11a/g Router has a built-in RADIUS server so users don’t have to setup a separate RADIUS for the use of WLAN 802.1x and WPA security policies and MAC address access control. To use the built-in RADIUS server, users have to select the “Enable Built-in Radius Server” check box. The built-in RADIUS server currently provides two types of authentication methods for EAP authentication: MD5 and TLS (i.e. EAP-MD5 or EAP-TLS). The way to configure the setting for the TLS type depends on whether the built-in CA (certificate authority) is enabled. The built-in CA is enabled by selecting the “Enable Built-in Certificate Authority” option. If the built-in CA is enabled, the built-in RADIUS server will use the built-in CA to issue its own certificate and requires all the user certificates issued by the built-in CA. So when the built-in CA is enabled, users do not have to 48
802.11a/g Router User’s Guide configure anything for the TLS type. If the built-in CA is not enabled, users have to enter the built-in RADIUS server’s certificate issued by an external CA (by specifying “Certificate Path”), the password to use the certificate (by specifying “Password”), and the certificate of the CA issuing all the user certificates (by specifying “Root CA Certificate Path”). The expected format for the built-in RADIUS server’s certificate is PEM (extension file name: .pem) and the expected format for the CA’s certificate is DER encoded binary X.509 (extension file name: .CER). Click the APPLY button to make the settings effective. Once the built-in RADIUS server is enabled, the “Use Built-in Radius Server” option at the “Radius Settings” page is automatically checked. The built-in RADIUS server does not require a user listed in its user database when TLS type is being used. So when the TLS type is selected, users do not have to add any user information into the built-in RADIUS server’s database. When the MD5 type is selected, users have to add the User Name and Password for each user into the built-in RADIUS server’s database. The database management is in the MD5 User Management section. A MD5 user can be removed from the database by selecting the user in the table and clicking the DELETE SELECTED button. For each RADIUS client that will use the built-in RADIUS server, users have to add a client entry in the “Radius Client Management” section. Name: a mnemonic name for the RADIUS client. IP Address: the IP address of the RADIUS client. Shared Secret: the shared secret pass phrase used to authenticate the RADIUS client. When the built-in RADIUS server is enabled, the PAP authentication function is always enabled. The PAP authentication function is used for WLAN MAC address control (the "Enable MAC Address Access Control" option at the "Radius Settings" page); in this case, the MAC address of an authorized WLAN client is used as both user name and password. A PAP user can be added in the PAP User Management section with the User Name and Password entered. A PAP user can be removed from the database by selecting the user in the table and clicking the DELETE SELECTED button. 49

802.11a/g Router User’s Guide CA Settings If you enable the “Built-in Certificate Authority” function at the “Radius Server Settings” page, you can see the “CA Settings” in the left side menu on “Advanced Settings” pages. The CA (Certification Authority) allows you to request certificates for WLAN clients/stations and for RADIUS servers. A certificate is required for a WLAN client and/or the RADIUS server when the WLAN security policy is 802.1x or WPA with the EAP type as TLS, PEAP, and TTL…. In the case where the RADIUS server will authenticate a WLAN client, the WLAN client needs to have a certificate for itself, and the RADIUS server needs to have the certificate of the CA issuing the client’s certificate. In the case where a WLAN client will authenticate the RADIUS server, the RADIUS server needs to have a certificate for itself, and the WLAN client needs to have the certificate of the CA issuing the RADIUS server’s certificate. To acquire a certificate for a WLAN client or a RADIUS server, enter the name and password for the client or server, and select the corresponding certificate type (“Normal User” for a WLAN client and “Radius Server” for a RADIUS server). Then click the EXPORT button and specify the file path to save the certificate on your PC. The User Name is used to identify the holder of the certificate to be issued, and the holder need the Password in order to use the issued certificate (so people not knowing the password cannot use the certificate). Currently the supported format for a “Normal User” certificate is PKCS #12 (extension file name: .p12), and the supported format for a “Radius Server” certificate is PEM (extension file name: .pem). To get the CA’s certificate, just click the EXPORT button and specify the file path to save the certificate on your PC. The format for the CA’s certificate is DER encoded binary X.509 (extension file name: .CER). 51
Dynamic DNS Settings Some people advertise the IP addresses of their routers so that Internet users can access these routers (which is actually to access virtual servers behind these routers) using these IP addresses. However, for those routers that are assigned dynamic IP addresses from the ISP, this approach requires additional work (since the addresses assigned are not always the same). The 802.11a/g Router implements the dynamic DNS feature so that each time it is booted, it will re-register its domain-name-to-IP-address mapping with the dynamic DNS server you use (currently only DynDNS.org is supported), the service provider that provides domain name to IP address mapping. This is so that you can advertise your router by providing your domain name, while Internet users can access the router using the domain name, not the router’s IP address. To activate this feature, you need to check the “Enable Dynamic DNS Client using DynDNS.org” box first, and then configure the following parameters: Hostname: the hostname (domain name) registered with DynDNS.org by you. Username: the username required to log in to the domain name server maintained by DynDNS.org. 52
802.11a/g Router User’s Guide Password: the password required to log in to the domain name server maintained by DynDNS.org. 53
Chapter 5 Managing your 802.11a/g Router This Chapter covers other management aspects of your 802.11a/g Router:  How to view the device status  How to view the system log  How to upgrade your 802.11a/g Router firmware  How to save or restore configuration changes  How to reboot your 802.11a/g Router  What if you forgot the password How to View the device Status You can monitor the system status and get general device information from the Device Information screen: 54
802.11a/g Router User’s Guide How to View the System Log The 802.11a/g Router maintains a system log that you can use to track events that have occurred in the system. Such event messages can sometimes be helpful in determining the cause of a problem that you may have encountered. You can select System Log on the left to view log events recorded in the system. The System Log entries are shown in the main screen along with the log level, the severity level of messages that are being displayed (a low number such as 2 means critical), and the uptime, the amount of time since the 802.11a/g Router was last reset. The maximum number of entries is 128. If there are more than 128 entries, older entries will be deleted. Security Log The 802.11 a/g Router maintains another log table for security logs. For each filter rule configured, the 802.11 a/g Router will monitor the traffic matching the rule. Once the rule’s hitting rate exceeds a certain degree (twice per 10 seconds, that is, more than one packet matching the rule in 10 seconds), a security log is generated and stored in the security log table. A security log entry contains a description regarding the event and a time stamp when the event happened. You can see the current logged security events from this page. Those log entries are not saved into flash, so all log messages are removed after the system reboot. The maximum number of entries is 128. If there are more than 128 entries, older entries will be deleted. 55
DHCP Client Table The DHCP client table lists current DHCP clients connected with its host name, IP address, MAC address, expiration time, entry type, and network type. 56
802.11a/g Router User’s Guide Wireless Client Table The wireless client table lists the current wireless clients with its MAC address, state, number of transmitted packets, and number of received packets. Bridge Table The bridge table shows all MAC entries learned from the wired LAN interface, wireless clients, and WDS peers. 57
WAN Status The WAN Status page shows the WAN connection status, including the public IP address assigned from the ISP and the DNS address. For the DCHP client connection, you can release and renew the WAN IP address; for the PPPoE connection, you can disconnect and connect the link. LAN Status This page displays the status of the 4 LAN ports. For each port, you can see the link status (Up/Down), duplex mode (Full/Half), and speed (10M/100M bps). 58
802.11a/g Router User’s Guide Upgrading Firmware You can upgrade your 802.11a/g Router’s firmware (the software that controls your 802.11a/g Router’s operation). Normally, this is done when a new version of firmware offers new features that you want, or solves problems you have encountered using the current version. System upgrade can be performed through the System Upgrade option as follows: Step 1 Select System Tools, then Firmware Upgrade from the menu and the following screen displays: 59
Step 2: To update the 802.11a/g Router firmware, first download the firmware from the distributor’s web site to your local disk.

802.11a/g Router User’s Guide Note: Resetting the 802.11a/g Router disconnects any active clients, and therefore will disrupt any current data traffic. What if you Forgot the Password? If you forgot the password, the only way to recover is to clear the device configuration and return the unit to its original state as shipped from the factory. You can do this by pressing the hardware “restore” button on the device for “2 seconds”. Please note that this will require you to re-enter all of your configuration data. 63
Chapter 6 Command Line Interface This chapter describes the Command Line Interface (CLI) for the 802.11 a/g Router. The CLI is accessible through a Telnet session. General guidelines When the 802.11 a/g Router is powered up, the user can use a standard telnet application from a PC connected to the network to perform configuration and management functions. This is done by typing the telnet command, “telnet <the 802.11 a/g Router’s ip>” (the default is 192.168.1.1) and pressing a return key, the user will see a system sign-on message followed by a password prompt as follows. Router Manager Console <rev_no> please enter your password: A default password “password” has been pre-configured with the system. The user should use it to log into the system until the password is explicitly changed using the change password command. Note that the entered password is case-sensitive. This password may also be changed using the browser-based GUI configuration utility. The password entered will be echoed back as asterisks (*). After the Carriage Return is entered, if the password string is validated, the command prompt Command> will be displayed, and the user can then issue other commands. Otherwise, the password prompt will be redisplayed. Most commands are single-line commands, and commands are not context sensitive: each command is independent of other commands before or after it. The command syntax is straightforward. The following briefly summarizes the guideline for the interface.  At any time, the user can type a “?” (preceded by a space) to request context-sensitive help on what the user can enter next.  At any time, the user can type control-p (^p, by pressing both the Ctrl key and the p key at the same time) to repeat the previous command, or control n to return to the following (next) command. At startup, typing ^p or ^n will not cause anything to happen - since previous commands do not yet exist. In normal operation, typing ^p will cause the previous command to show, and the cursor will sit at the end of the command. At this point, the user can either type a carriage return to accept the command, or type backspaces to edit the command from the end. Up to 15 previously entered commands can be invoked through ^p’s and ^n’s. 64
802.11a/g Router User’s Guide  If a keyword is expected when the user types “ ?”, all valid keywords will be displayed. The command typed in so far will then be displayed again along with the cursor sitting at the end, waiting for the user to continue.  If the user types in part of the keyword but does not type in the entire word, the user can then enter a tab or space for the system to automatically complete the keyword if the characters typed in so far can uniquely identify the keyword. If the characters typed in so far do not uniquely identify a keyword, a list of possible keywords will be displayed. If the user is not sure what to type next, he or she can type "?” to display the possible keywords that match the current CLI command input. If an interactive mode is entered, the system will prompt for each required parameter, such as: … Command> add radius server primary enter server IP (Unspecified): 192.168.1.10 enter port number (1812, 1-65535): 1812 enter shared secret: … The first prompt means current IP setting is not specified yet, and there is no default for that. The second prompt means a number between 1 and 65535 is expected, with 1812 being the default. During the first time a particular parameter is configured, typing a carriage return will cause the default value to be selected. Otherwise, typing a carriage return means no change to the current value. Express Mode vs. Advanced Mode of operation The Command Line Interface operates in one of two modes: Express Mode or AdvancedMode. In Express Mode, not all parameters are displayed. Default values are set for those parameters not displayed in multi-line commands. In Advanced Mode, users have the option to modify all possible values appropriate to each operation. The user can toggle between Express Mode and Advanced Mode by typing ^E (Control-E) at any time. Normally, the system prompt will be changed by appending “>>” to the configured prompt when in Advanced Mode. Conventions The following notations will be used:  lan means the LAN port;  wlan means the Wireless port; 65
 <> specifies the arguments of the command, <1-4> means a number between 1 to 4;  [ ] indicates an optional parameter  | is used to separate alternative choices of parameters or keywords;  {} encloses all alternative keywords;  MacAddr, or XX-XX-XX-XX-XX-XX means any MAC address in hexadecimal format, where each XX can be 00, 01, ... 99, 0A, 0B, 0C, 0D, 0E, 0F, 10, 11,… FF;  ipAddr, netmask, or xxx.xxx.xxx.xxx means any ip address or network mask, where xxx is a decimal integer between 0 and 255;  The term string means a string of characters up to the specified length, which may be enclosed in double quotes (“) (required if the string contains embedded blanks);  Names representing filters and MAC addresses could be up to 30 characters in length; password and SNMP community read/write strings are up to 15 characters in length. When the password and SNMP community write string are entered, they are echoed back as a string of “*”s for protection, while other parameters, such as WEP keys, are echoed back the way they are typed (in clear text). List of Commands From a functional point of view, CLI commands will be grouped into the following categories: (1) System (2) IP (3) Filtering (4) DHCP Server (5) SNMP (6) Diagnostics (7) Security The command format will be described in the following sections.

Text Configuration The text configuration provides another way for users to configure the 802.11 a/g Router. Users can save the system current configuration onto a file on PC, edit the configuration file, and then restore the system configuration with the configuration file. For details regarding the save and restore configuration operations, please read the HOW TO SAVE OR RESTORE CONFIGURATION CHANGES section in the MANAGING YOUR 802.11A/G ROUTER chapter. This chapter describes the syntax and semantics of a text configuration file. General guidelines The format of a text configuration file is like the Microsoft Window® INI (extension file name: .ini) file format. The basic file structure can be divided into the following parts: 1. Sections A section name is enclosed in square brackets, alone on a line. Section names are allowed to contain any character but square brackets or linefeeds. For example: “[sectionName]”. Basically a section corresponds to a configuration item, a section contains zero or more key and value pairs that are the settings for the configuration item. A section name is case insensitive. 2. Keys and Values A section contains zero or more key and value pairs, declared with the syntax “key = value”. A key is a string without space and the value consists of all characters at the right hand side of the equal sign. That is, a key starts with the first non-blank ASCII character at the right hand side of an equal sign and extends to a comment mark (if there is one) or the end of the line. So blanks are allowed among non-blank characters. A key string is case insensitive. 3. Comments A comment starts with a semicolon or a hash sign and extends to the end of the line. List of Sections Section & Examples Description [Manufacture] This is used by the system itself, and this should be Chapter 6 74
