Wireless Router User Guide 

 

88

• 

Access Points use a fixed Channel. You can select the Channel used. This allows you to 
choose a Channel which provides the least interference and best performance. In the USA 
and Canada, 11 channels are available. If using multiple Access Points, it is better if adja-
cent Access Points use different Channels to reduce interference. 

• 

In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an 
Access Point. If more than one Access Point can be used, the one with the strongest signal 
is used. (This can only happen within an ESS.) 

• 

If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the 
same Channel. However, most Wireless stations will still scan all Channels to see if there 
is an existing "Ad-hoc" group they can join. 

B.4 WEP 

WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted.  

This is desirable because it is impossible to prevent snoopers from receiving any data which is 
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless 
unless the receiver can decrypt it. 

If WEP is used, the Wireless Stations and the Access Point must have the same settings 
for each of the following: 

WEP 

Off, 64 Bit, 128 Bit, 256 Bit 

Key 

For 64 Bit encryption, the Key value must match.  
For 128 Bit encryption, the Key value must match 
For 256 Bit encryption, the Key value must match 

WEP Authentication 

Open System or Shared Key. 

 

B.5 Wireless LAN Configuration 

To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point 
must use the same settings, as follows: 

Mode 

On client Wireless Stations, the mode must be set to "Infrastructure". 
(The Access Point is always in "Infrastructure" mode.) 

SSID (ESSID) 

Wireless Stations should use the same SSID (ESSID) as the Access 
Point they wish to connect to. Alternatively, the SSID can be set to "any" 
or null (blank) to allow connection to any Access Point. 

WEP 

The Wireless Stations and the Access Point must use the same settings 
for WEP (Off, 64 Bit, 128 Bit or 256 Bit). 

WEP Key:

  If WEP is enabled, the Key must be the same on the Wire-

less Stations and the Access Point. 

WEP Authentication:

  If WEP is enabled, all Wireless Stations must 

use the same setting as the Access Point (either "Open System" or 
"Shared Key").
