This chapter provides information on the Wizard Setup screens in the Web Confi guration
Utility.
3.1 Wizard Setup Overview
The Web Confi guration Utility’s setup wizard helps you confi gure your WR3000 Wireless
Router for Internet access and set up wireless LAN.
3.1.1 Channel
The range of radio frequencies used by IEEE 802.1 lb wireless devices is called a “channel”.
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 (Wireless Router)
to reduce interference. Interference occurs when radio signals from different Wireless Routers
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 fi ve 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 WR3000 Wireless Router’s “Scan” function is especially designed to automatically scan
for a channel with the least interference.
3.1.2 ESSID
An Extended Service Set (ESS) is a group of Wireless Routers or wireless gateways
connected to a wired LAN on the same subnet. An ESS ID uniquely identifi es each set. All
Wireless Routers or wireless gateways and their associated wireless stations in the same set
must have the same ESSID.
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 Wireless Routers to keep network communications private. It encrypts unicast and
multicast communications in a network. Both the wireless stations and the Wireless Routers
must use the same WEP key for data encryption and decryption.
