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.

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 Rou ter can automat ically
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 r emote user s across the I nternet (e.g., an e-mail s erver, 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 Po int
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 sever al ways to keep y our n etwork 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 us e to selectively filt er (disc ard) packets to/from the Internet.
You can selectively restrict management to remote dev ices.
To address the growing security conc ern in a wir eless LAN envir onment, differ ent levels of s ecurit y
can also be enabled in the 8 02.11a/g Ro uter, in cluding:
To disable SSID broadca st so to restrict association to only client stations that are already pre-
configured with the correct SSID.
To enable WEP (Wireless Encryption Protocol) en cry ption to implement priva cy 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 (PreShared Key) for SOHO users.
802.11a/g Router Features
Compliant with 802.11a, 802.11b, and 802.11g stand ards with roaming cap ability
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) p ass-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

Access Control List, to enable WEP based encryption (up to 152 bits), to enable WPA, plus
the enhanced security with 802.1x using a prim ary an d a backup RADIUS S erver
Extensive monitoring capability such as event l ogging, 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 wirel ess LAN network. T o
do this, the 802.11a/g Router must have an IP address, which can be statically configured, or is
dynamically obtained from a DH CP server on the LAN. For reasons to be given in Chapter 3, static IP
address assignment is much preferred.

High Level Configuration Steps Require d 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 n etwork mas k of 255.255.255.0).
11
Setting up a Windows PC or wireless client as DHCP clie nts
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 interfac e installed prope rly,
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 net wor k.
Configuring a PC running MS-Win dows 95/98 /Me:
1. Click the Start Button, and select Settings.
2. Click the Control Panel. The Win9 5/98/Me Control Panel will appear.
3. Open the Network setup window by double-clicking th e Network icon.
4. Check your list of Network items. If TCP/IP is already installed, pro ceed to step 5. Otherwise:
(You may need your Windows CD to complete th e installation of T CP/IP.)
Click the ADD button.
In the Network Component Type dialog box, select Protocol.
In the Select Network Protocol dialog bo x, sele ct 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 an d verif y the following s ettings:
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 f or WI NS Re soluti on.
IP address: Select the Obtain IP address automatically radio button.

6. Click OK to finish the configuration.
Confirming your PC’s IP Confi guration:
There are two tools useful for finding out a computer's I P address and def ault 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 ca n also type winip cfg 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 dynami call y, you should specify the IP addres s explicitly.
Connecting More Devices Through A Switch /Hub To The 802.1 1a/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 devic es, you can conn ect an external hub or
switch to any of the LAN ports using a L AN cable.
13
Basic Configuration of the 802.11a/g R outer
Chapter
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 I nternet Ex plorer 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/
.
3
Note: 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. Sele cting any will allo w you to navig ate to other configuration menus .
Logging On
14
802.11a/g Router Use r’s Gui de
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 in activity 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 Wizar d
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 mod ificatio ns 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 “N EXT”.
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 Use r’s Gui de
• 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
Unnumbered Link
: This option only supports one PPPoE session.
: This option can let your LAN be a public IP subnet. Th at 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 thi s 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 Addres s: the IP address on the local side of the PPTP tunnel provided
by your ISP.
• PPTP IP Netmas k: 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

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 add ed
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

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 I P addr ess 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 fiel ds
IP Address and IP Subnet Mask: These values default to 192.168.1.1 and 255.25 5.255.0, resp ectively.
This IP address can be modified if necessa ry, to either a differe nt 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 en abled, th e 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

order to access it, you will need to use UPnP (Univ ersal Plug and Play) or other management tools that
do not depend on a fixed IP address.
It is strongly recommended that you sel ect the manu al static I P 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 devi ce to broadc ast 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 802.11 g
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 s ame channel and shar e the total b andwidth av ailabl e.
Note: The available channels are diff erent from countr y to country and f or differe nt WLAN mode.
Security Policy: You can select different security policy to provide association authentication and/or
data encryption.

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 f ormat.
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 WEP 152, you can m anually configur e 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 ke y looks like "An ASCII key!"
(13 characters), while a WEP64 hex key looks like "44-12-24-A8-B2" (5 bytes) and “11-22-33-44-5566-77-88-99-00-A3-BB-2C” as WEP128 hex key. Each set of hexadecimal numbers should be
separated by “-“(dash).

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 wil l be generated aut omatically and dynamicall y.
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 clie nt stations us e the same key.
Encryption Type: There are two encryption types TKIP and CCMP (AES). While CCMP provides
better security than TKIP, some w ireless 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 ch ange the gr oup k ey periodic ally . The shorter th e interval is, the b etter
the security is. 60 seconds is a reason able tim e, and it is used by defa ult.
WPA
Wi-Fi Protected Access (WPA) requires a RADIUS server available in order to do authentication (same
as 802.1x), thus there is no shar ed key required.
The Encryption Type and Group Rekey Interval settings are same as WPA-PSK.
