[Bug 629560] [NEW] Wi-fi doesn't work when booting or resuming from suspend while on battery

[Emmanuel Pacaud]

Public bug reported:

When I start my laptop, running on batteries, wifi failed to work
properly.

Network manager shows a message saying my laptop is connected to my wifi
network, but in fact the newtork is unreachable. After a while, network
manager shows a "broken network" icon (with the red exclamation mark).

I'm able to make the wifi works by switching off then on the radio
devices (RF_KILL switch).
