Please attach the output of running 'dmesg' shortly after booting and attempting to bring-up the interface. Do you have the proper firmware installed?
Created attachment 158525 [details] output from dmesg The interesting part starts at line 428
The wireless interface works OK with Windows, so I would expect the firmware is correct.

Created attachment 158628 [details] bcm43xx-mac80211.example Did you actually ifup the interface before running dmesg? I'm attaching example dmesg output from my bcm4318 pccard on my FC6 Thinkpad. Please notice how your dmesg lacks the corresponding lines starting with the "Adding Interface" line. This should have been tiggered by ifup or the equivalent "ifconfig wlan0 up" or similar.
Also, based on comment 7 I have to ask if you have run bcm43xx-fwcutter, and if so what driver you used to source the firmware?
Created attachment 158685 [details] Output from dmesg including ifup wlan0 Here is the output from dmesg including when ifup wlan0 was run. I see it is looking for bcm43xx_microcode5.fw. I found the file Windows is using for a driver, bcmwl6.sys, but fwcutter refuses to run on it, saying it is an unrecognized file.
Here is what Windows Vista says about \\windows\system32\drivers\bcmwl6.sys File description: BCM 802.11g Network Adapter wireless Type: System File File version: 4.82.28.56 Product name: BCM 802.11g Network Adapter wireless Copyright: 1988-2006, Broadcom Corporation, All Rights Size: 453 KB Date modified: 11/2/2006 2:30 AM Language: Language Neutral
Try this procedure: # you need to be root wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2 tar -xjvf broadcom-wl-4.80.53.0.tar.bz2 bcm43xx-fwcutter -w /lib/firmware/ broadcom-wl-4.80.53.0/kmod/wl_apsta.o Follow that by either 'modprobe -r bcm43xx-mac80211 ; modprobe bcm43xx-mac80211' or simply reboot. Does that work any better for you?

Here is what ifup said: [root@orchard-laptop-2 network-scripts]# ifup wlan0 Error for wireless request "Set Bit Rate" (8B20) : SET failed on device wlan0 ; Operation not supported. Determining IP information for wlan0... From dmesg, it looks like it found the firmware
All that looks fine. Do you get a usable connection?
