How to discover which WiFi AP is being used on Windows 7/8

When you have multiple access point and you want to see, how you are roaming between them and which one is currently in use, then you can monitor this using following procedure:

1. Press Win+R, Run windows appears
   
2. Paste following text:
   powershell do {cls ; netsh wlan show int | findstr SSID ; netsh wlan show networks mode=Bssid | findstr SSID ; sleep 1} while (1)
3. Press OK
   

Then you can see which WiFi network you are using and which WiFi AP you are using (WiFi AP-s MAC address). Also you can see, which AP-s are visible.

In my case I have two network visible, both with 5 different AP-s. First two lines show What network I’m using (SSID) and which AP I am connected to (BSSID).
