Hah, just my luck...seems as though everyone on this thread with a "Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)" card hasn't been able to get this working . I followed this guide to a T and though it seems as though it should be working (laptop light finally coming on and no "hanging" when configuring in the Network Manager"), I get nothing. Here is what I've done...

Code:
root@lappy:~# lspci | grep Broadcom\ Corporation
0000:06:02.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
Prerequisite
Ubuntu dapper *check*
A wireless card that shows up in Ubuntu *check*
A driver installation CD (for Windows) OR a driver for your card from the internet *check* (downloaded from http://sidulus.textdrive.com/bcmwl5sys.zip)
Access to the Ubuntu Universe Repository *check*

Did this:

Code:
root@lappy:~# apt-get install bcm43xx-fwcutter
When running:

Code:
root@lappy:~# bcm43xx-fwcutter -w /lib/firmware ~/Desktop/bcmwl5.sys
...I get:

Code:
*****: Sorry, it's not posible to extract "bcm43xx_microcode11.fw".
*****: Extracting firmware from an old driver is bad. Choose a more recent one.
*****: Luckily bcm43xx driver doesn't include microcode11 uploads at the moment.*****: But this can be added in the future...
...but it still appears to install the files into the firmware directory.

Did this:

Code:
root@lappy:~# apt-get install network-manager-gnome
And after a reboot and even trying this:

Code:
root@lappy:~# modprobe bcm43xx
...I get nothing. I've been playing around with this for hours now and am pretty much stuck. Here is some debug information (eth1 is the wlan card):

Code:
root@lappy:~# iwconfig

I have reset ALL the router settings so there's no WEP (or any encryption at all), copied/pasted the SSID into the Network Manager and even tried statically assigning the IP address. But still nothing . And nothing shows up in the Gnome panel for wifi either. Has anyone gotten this specific card to work??? Any help would be GREATLY appreciated.

Thanks in advance!
