Strange problem with Slackware & Intel Pro/Wireless 2200BG

Hello guys! I'm just registered.

I've a strange problem with wifi. I've an Acer Travelmate 292LCi with Intel PRO/Wireless 2200BG wifi card. I've installed the latest drivers and firmware from according to the INSTALL guide from the site. But I have a very strange problem!This notebook have a led on the case that turns on when the wifi card is active. The problem is that wifi works only if I first start Windows and then reboot and switch on linux!!! I use Slackware 10.1 with 2.6.10 kernel.

When I turn on the notebook the led is off and turns on only when I start Windows. If i turn on and boot directly on linux the led stays off and I get the following error:

ipw2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.

As specified here I launch this comand

cat /sys/bus/pci/drivers/ipw2200/0000\:02\:02.0/rf_kill

and it should give me 0, it does!!!

According to the install istruction the following command:

grep CONFIG_FW_LOADER /lib/modules/`uname -r`/build/include/linux/autoconf.h

gives me : #define CONFIG_FW_LOADER_MODULE 1

and the following: grep CONFIG_NET_RADIO /lib/modules/`uname -r`/build/include/linux/autoconf.h

gives me:


So it should be all right! Why Linux doesn't activate the wifi card? If i start windows and then linux the led stays on and wireless works perfectly!!! (I'm using it in this moment)

Please help me.

Welcome to LQ!

You might find some ideas here:

Sounds like you may need a linux driver for controlling the kill switch from linux.
