Site Survey

 

Site Survey

 scans the wireless networking frequency band and displays the results. 

For each wireless network that the utility detects, it displays the domain name 
(SSID), BSSID (MAC address), current channel, signal strength, network mode, 
WEP setting, and estimated distance. It also gives you the option of selecting a 
particular access point or network to associate with (join). 

When 

Site Survey

 is run, “Start scanning” appears in the title bar while the search 

is in progress. If any networks are found, the results appear in ten seconds. The 
information is not dynamically updated. To refresh the data, click the 

Scan

 button. 

The Signal Strength column shows either green (strong signal), or yellow (average 
signal).
