Windows CLI show wireless infomation

Ref: http://www.speedguide.net/faq_in_q.php?qid=346

Under Windows Vista/7/2008, the default GUI wireless network list does not display the channels access points use. To find the channels, you have to do the following:

1. Navigate to Start > Run, type: cmd to enter command prompt
2. Type: netsh wlan show all
2a. Alternatively, type: netsh wlan show networks mode=bssid

This will display a list of all wireless networks in range, along with the network channel, signal strength, and security type used.

Ideally, you should pick a channel that is at least 3 channels apart from those used by other networks in the area.
