Bug Description

Reproduce:
1. Connect to a wifi
2. Reboot wifi router

What happens:
I am not reconnected, neither does the AP appear in nm-applet

What should happen:
I should be reconnected as soon as the AP is up again

Running $ sudo wpa_cli and doing a scan + scan_results shows the AP almost immediately after it comes back up.
