Figure 26   

Configuration Screen

Enable Wireless Networking

Allows you to enable/disable the wireless section of your LAN. When 
disabled, no wireless PCs can gain access to your Wired or Wireless LAN 
through this Access Point.

Channel Selection

The Channel Selector allows you to specify which Channel the Access 
Point will transmit and receive on. If someone else nearby is using the 
same Channel as you, there will be a reduction in the performance of 
your network. If this seems to be the case, you should select a different 
channel number. Usually the Wireless computers will scan to find the 
correct channel, but if they don't you must configure them to use the 
same Channel number as the Access Point.

Valid channels are country dependent. See 

“Channels”

 on 

page 83

 for a 

list of channels approved by each country.

Clear Channel Select

 allows the Access Point to automatically select the 

optimum channel when first powered on.
