Bug Description
I noticed last night that one of my wireless access points was not listed in nm-applet, which seemed odd given that it was only 2 metres away. I thought that disabling and re-enabling the wifi might cause a rescan, so I clicked Disable wireless networking in nm-applet. Now, nm-applet will not allow me to re-enable wireless - the section in the drop-down is greyed out, and says "wireless is disabled by hardware switch", even though the wireless card is enabled.

I managed to restore my wifi using the rfkill command as described here:

I had to reboot for the device to become available, however, and I'd like to understand how NetworkManager got itself in such a state in the first place.
