Tested today with bgscan added. Didn=E2=80=99t connect to home network unti= l I manually run ifconfig wlan0 scan. Again, this is with failover lagg. It did however realize I wasn=E2=80=99t at the office anymore and the ssid = field was empty in ifconfig output. Sometimes it stays the same long after I leave the network.
