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. ProblemType: Bug Architecture: amd64 DistroRelease: Ubuntu 9.04 MachineType: Dell Inc.
