On a Thinkpad X220 (i7 sandybridge with Intel wifi) 1. Turn off wifi, either by using fn+F4, or networkmanager's "turn of the wifi" slider in gnome shell's network menu, or using gnome-control-center's "airplane mode", or using "rfkill block wifi". 2. The wifi LED on the thinkpad turns off, but networkmanager's "wifi connected" icon stays unmoved. 3. Turn wifi back on... now networkmanager's icon changes to "disconnected" and then proceeds to reconnect to the wifi. Trying to ping 8.8.8.8 seems to hint that it is only nm's gnome-shell status icon that is borked up.
I'll add that this also occurs with the hardware RF killswitch on the Thinkpad - gnome-shell still shows a "wifi connected" icon even though the hardware is completely turned off and ping says the network is unavailable.
This would be better reported upstream: http://bugzilla.gnome.org/
Already reported upstream: https://bugzilla.gnome.org/show_bug.cgi?id=676285
Thanks!
It'll get fixed in 0.9.8.2 and 0.9.10; fix is already upstream.
