Can't turn off RF Kill switch on Asus Z33A with Intel 2200BG wireless

I can't for the life of me turn off the stupid RF Kill switch on my brand new Asus Z33A. I'm running Debian, but I don't think this is a Linux problem. After modprobe ipw2200, I get:

ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.4
ipw2200: Copyright(c) 2003-2004 Intel Corporation
ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
ip2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.

# cat /sys/bus/pci/devices/*/rf_kill

which means the ip2200 driver detected a HW RF switch. I've tried Fn+F2 (which has the little wireless icon in blue), but that doesn't seem to do anything. The wireless LED on the laptop is off. I also tried opening the back and pressing on the RF connectors to make sure they were connected, but they seemed pretty secure to me.

# iwlist eth1 scan
eth1 No scan results

which is clearly wrong, as my laptop is literally 2 feet away from my wireless router.

I also tried:
# modprobe asus_acpi
# echo 1 > /proc/acpi/asus/wled

then reloading the ipw module. This has no effect, the kill switch is still on

Has anyone else had this problem?

Thanks in advance,

Had the same problem (Asus Z33A also)

Heres how I fixed it:

1) Install ipw2200 (

2) Install ipw2200 firmware (from the above site)

3) Upgraded to the latest BIOS
