Your radio is disabled by the software rf_kill switch. Please do a

$ echo 0 > /sys/bus/pci/drivers/iwl4965/<dev id>/rfkill\:rfkill0/state

I wonder if you (or some application) did something like a `iwconfig
wlan0 txpower off` so that the radio is disabled. Maybe you can try
`iwconfig wlan0 txpower on`?

Thanks,
