First, connect your phablet to PC and copy over your connection info:
# phablet-network -n
/etc/NetworkManager/system-connections/YourSSID.conf
or just create new .conf file on the phablet at /etc/NetworkManager/system-connections/YourSSID.conf
.
Start adbd as root
# adb root
Enter shell
# adb shell
Edit file (if you don't like vi, you can always use ed :), not sure if there is any other editor available. You could also edit this file directly on your PC)
# vi
/etc/NetworkManager/system-connections/active_ws_connection.conf
under [802-11-wireless]
add:
seen-bssids=00:00:00:00:00:00;
replace with MAC address of your AP.
Save file and reboot
