This section introduces the wireless LAN and some basic configurations. Wireless LAN can be as simple as two computers with wireless LAN cards communicating in
a peer-to-peer network or as complex as a number of computers with wireless LAN cards communicating through access points (AP) that bridge network traffic to the
wired LAN.
The Modem Wi-Fi® certified IEEE 802.11g compliant wireless access point allows multiple computers to connect wirelessly to your local network over the Modem
Wireless LAN environment. The Modem is backward compatible with IEEE 802.11b, which means 802.11b and 802.11g devices can coexist in the same wireless
network. The Wireless Distribution System (WDS) on your Modem allows you to extend the range of your wireless network. To be able to use WDS, you will need to
introduce an additional WDS-enabled access point into your wireless network. To be able to connect the computers, make sure that a wireless client adapter (WLAN
client) is installed on each computer you want to connect via the WLAN.

Wireless LAN Basics

Some basic understanding of 802.11b/g wireless technology and terminology is useful when you are setting up the Router or any wireless access point. If you are not
familiar with wireless networks please take a few minutes to learn the basics.
Wireless client requirements
All wireless client adapters compliant to 802.11g and/or 802.11b can communicate with the Modem (W) LAN environment. However, be aware that only 802.11g
compliant wireless clients are able to gain full profit of the 54 Mb/s (Max) bandwidth delivered by the Modem. It is highly recommended to use only wireless client
adapters that are Wi-Fi™ certified to ensure smooth interoperability with the Modem's WLAN.
Radio Transmission
Wireless LAN or WLAN devices use electromagnetic waves within a broad, unlicensed range of the radio spectrum to transmit and receive radio signals. When a
wireless access point is present, it becomes a base station for the WLAN nodes in its broadcast range. WLAN nodes transmit digital data using FM (frequency
