Need help to get wireless nic working

[jerry]

I  have read and tried several howtos and tutorials but no success. I 
have tried so many ways to do it that I am not sure now if some of the 
left over detritus of past attempts is preventing the card from working.

I have a spare computer (1 Gz cpu, 380 MB ram, 6 GB hd) that I did a 
clean install (all partitions reformatted)  with Kubuntu 6.06 LTS using 
the x86 alternate cd. NIC is Linksys WMP54G PCI that works in windows 
XP. I have  a router (Linksys WRT54GL) on my main computer (also Kubuntu 
with wired nic). I do not have WEP  nor WAP turned on and am using MAC 
filtering. I am sure the MAC addresses are correct.

The howto that I have found that is closest to my hardware  is posted on 
Dossy's blog (Linksys WMP54GS with broadcom bcm4306 and 2.6 kernel) and 
is what I am currently using.

During the install I got a message " Network Autoconfig failed" and no 
matter which option I tried to configure the nic the install could not 
find the wireless network.

After the install completed and reboot,the green light on the nic does 
not light up.
I tried to follow the howto. Here is some info:

lspci -v
0000:00:08.0 Network controller: Broadcom Corporation BCM4306 802.11b/g 
Wireless LAN Controller (rev 02)

lspci -n
0000:00:08.0 0280: 14e4:4320 (rev 02

I put ndiswrapper-1.1.tar.gz in my home directory, untared it and ran 
the script ./ndiswrapper, and ./ndiswrapper -m added the module to 
/etc/modprobe.d/ndiswrapper

I also copied bcm43xx.cat, BCMWL5.inf, and bcmwl5.sys  into the home dir 
and ran:
sudo ./ndiswrapper -i BCMWL5.inf
installing bcmwl5

jerry at backup:~/ndiswrapper-1.1/utils$ ./ndiswrapper -l
Installed ndis drivers:
bcmwl5  driver present, hardware present

I ran "modprobe ndiswrapper" and now ndiswrapper is listed in lsmod.

Reboot and  still no success. System Settings ->Connections does not 
show a wireless connection present. Network Settings shows the nic as 
disabled. If I click on the enable interface button the nic shows 
enabled for a fraction of a second and returns to disabled.

I am at a loss on how to get the nic working and would appreciate any 
advice.

Thanks
