Re: Trouble getting bcm43xx driver to work
Hi,
I tried the bcm43xx-dscape driver with a patched 2.6.15 kernel on my
iBook G4 12" and I cannot get it to work. Some relevant information...

I am using the January 10, 2006 snapshot of bcm43xx on 2.6.15 kernel
with the unofficial patch available at bcm43xx.berlios.de
Once the kernel boots up, modprobe rate_control 80211 and insmod
bcm43xx.ko works without errors. The relevant dmesg output
80211: module license 'unspecified' taints kernel.

However, the script sta_up.sh caused the kernel to crash (can someone
tell me what to dump from xmon. I am not sure what information in
there is relevant). I traced the crash to the following command in the
script sta_up.sh
ifconfig wlan0.11 up
Instead I tried
ifconfig wlan0 up and then proceeded with the remaining steps in
sta_up.sh manually and dmesg output shows...

I have to use WEP and I don't have any open routers or WPA routers to
test these options. The router is a Linksys WRT54G model. So my
questions are...
1. Any suggestions on how I can avoid the kernel panic when I do
"ifconfig wlan0.11 up"? What information should I provide so that
someone can help me with that? I have xmon enabled in my kernel and I
can post the relevant information.
2. Is my wireless card really working if I replace "ifconfig wlan0.11
up" with "ifconfig wlan0 up"?
I have also tried the softmac-bcm43xx approach, but without
success. The softmac spews out errors complaining that it cannot
associate without authenticating and forever tries to authenticate
with the router.
