Public bug reported:
On a Dell E6500, after unsuspending my laptop, I noticed my WiFi and 3G
cell card LEDs were off. Tried hitting moving the switch on the side
that enables both, and only the 3G LED came on.
/var/log/messages shows the iwlagn kernel module thinks that:
kernel: [347888.386364] iwlagn: Radio Frequency Kill Switch is On:
kernel: [347888.386370] Kill switch must be turned off for wireless networking
to work.
However, the switch is "on".
Resolved completely in software by first removing modules: 'modprobe -r
iwlagn; modprobe -r mac80211; modprobe -r cfg80211'.
Then did 'modprobe iwlagn' followed by 'ifup wlan0'.
Works fine after that.
