3.1 Wizard Setup Overview

The web configurator's setup wizard helps you configure your ZyAIR for wireless stations to
access your wired LAN.

3.1.1 Channel

A channel is the radio frequency(ies) used by IEEE 802.11b and IEEE 802.11g wireless
devices. Channels available depend on your geographical area. You may have a choice of
channels (for your region) so you should use a different channel than an adjacent AP (access
point) to reduce interference. Interference occurs when radio signals from different access
points overlap causing interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap, your AP
should be on a channel at least five channels away from a channel that an adjacent AP is using.
For example, if your region has 11 channels and an adjacent AP is using channel 1, then you
need to select a channel between 6 or 11.
The ZyAIR's "Scan" function is especially designed to automatically scan for a channel with
the least interference.

3.1.2 ESS ID

An Extended Service Set (ESS) is a group of access points connected to a wired LAN on the
same subnet. An SS ID uniquely identifies each set. All access points and their associated
wireless stations in the same set must have the same SSID.

3.1.3 WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network. WEP encryption scrambles the data transmitted between the wireless stations and the
access points to keep network communications private. It encrypts unicast and multicast
communications in a network. Both the wireless stations and the access points must use the
same WEP key for data encryption and decryption.
