description |
The symptoms I see are very similar to bug 193970 but with a different wireless chipset. I can't tell whether it's the same problem or not, so I'm filing a separate bug as it's easier to merge them than to tear them apart.
If I turn off the (physical) RF kill switch after it has been on (either since boot or after having activated it manually), the LED never turns on and the card doesn't scan:
perseus:[~] sudo iwlist wlan0 scan
wlan0 No scan results
Nothing is shown in dmesg from iwlagn when I turn off the kill switch, but other RF devices in the system change state, so I can see that it's working:
[ 1622.808097] usb 5-1: new full speed USB device using uhci_hcd and address 3

Unloading and reloading the module gets it working, i.e. the LED turns on and scanning works:

perseus:[~] sudo iwlist wlan0 scan

Once I've done this, I can toggle the switch on, confirm no scan results, turn it back on, and get results again.
