Problems with WPA2/AES and Broadcom BCM4318 (AirForce One 54g)

[Robert Scheck]

Good evening folks,

I've problems with setting up WPA2/AES at my HP Pavilion ze2000
(EH708EA#ABD) notebook. It's running Fedora 7 with any updates
(2.6.21-1.3228.fc7, i686 architecture). Below are the facts from the
notebook itself and what I already tried.

# lspci | grep Wireless

        Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 64
        Interrupt: pin A routed to IRQ 3
        Region 0: Memory at c0204000 (32-bit, non-prefetchable) [size=8K]

I installed ndiswrapper via "yum install ndiswrapper kmod-ndiswrapper -y"
from Livna without any error. After that I followed the typical install
method, because the standard bcm43xx-mac80211 kernel module driver doesn't
work for me (I'm not able to enable the kill switch, my notebook provides).

# rmmod bcm43xx-mac80211
#

# echo "blacklist bcm43xx_mac80211" >> /etc/modprobe.d/blacklist
# 

# echo "alias wlan0 ndiswrapper" >> /etc/modprobe.conf
# 

# cd /tmp
# 

# wget -q http://biginoz.free.fr/linux/bcmwl5a.inf
# 

# wget -q http://biginoz.free.fr/linux/bcmwl5.sys
# 

# ndiswrapper -i /tmp/bcmwl5a.inf

Looks like proto "WPA2" isn't supported which seems to be the reason that
my WPA2/AES setup doesn't work. Using Windows XP the stuff works...so does
anybody of you have an idea to get WPA2/AES working at Fedora, too?

Oh and WLAN without any encryption works, of course.
