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.

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 four-port 10/100Mbps Ethernet switch for connection to PCs on
your local wired network, and two wireless interfaces for connection to your local wireless network:
one supports 802.11a, another can be configured to support either both 802.11b and 802.11g or
802.11g only (both radios support a data rate of up to 54 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 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 54 Mbps. It allows client devices on
4

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.
Besides, the 802.11a+g Router also provides connection to 802.11a client devices. It can provide both
802.11a and 802.11b/g connections simultaneously.
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.
 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 from 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 correct SSIDs
 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).
5

 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 pass-through
 Support of PPPoE and PPTP client function for xDSL connections
 Support of Internet Games (WarCraftIII, AOEII) 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
 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
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
A local PC on either the wired or wireless LAN network can manage the 802.11a+g Router. 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.
