The drivers look OK.

Try the following commands:

iw dev | grep Interface
sudo iw dev XXXXX scan | egrep "signal|SSID"

Replace the XXXXX with the device name listed on the "Interface" line following 
the first command. Post the output of the second command and indicate which SSID 
is from your AP.
