Just to be sure, I tried installing v4 firmware as per the instructions above. It was a mini-disaster. First, for the firmware which would seem to apply to my card, listed under bcmwl5.sys, both the links listed in the readme seem to be broken:
4.10.40.0 http://rapidshare.de/files/11458737/Broadcom_4.10.40.0_Drivers.cab.html 4.10.40.1 http://images.lunarpages.com/12002219.cab The first url fetches something with a 2.7Kb size with an invalid MD5 checksum: $ wget http://rapidshare.de/files/11458737/Broadcom_4.10.40.0_Drivers.cab.html 15:23:38 (776.16 KB/s) - `Broadcom_4.10.40.0_Drivers.cab.html' saved [2748/2748] $ ./bcm43xx-fwcutter Broadcom_4.10.40.0_Drivers.cab.html Sorry, the input file is either wrong or not supported by bcm43xx-fwcutter. This file has an unknown MD5sum 780716436b475d93b9032c5b1549b1f7. The second url is completely invalid: $ wget http://images.lunarpages.com/12002219.cab --15:26:05-- http://images.lunarpages.com/12002219.cab => `12002219.cab' Resolving images.lunarpages.com... failed: Name or service not known. Not to be deterred, I tried the wl_apsta.o driver: $ wget http://downloads.openwrt.org/sources/broadcom- wl-4.80.53.0.tar.bz2 Then I ran the fwcutter and copied to /lib/firmware and booted on the 2.6.20.8 kernel. Disaster. The wireless light on my laptop activated bringing hope, but the whole system locked up when I actually tried to connect to a network. Checking dmesg output revealed the folllowing: [ 76.061108] bcm43xx: Firmware: no support for microcode extracted from version 4.x binary drivers. So I recut the firmware from the original windows driver, deleted the firmware in /lib/firmware, recopied the original firmware, rebooted on 2.6.20.6, and was able to use my wireless card once again, to my relief. -- Broadcom bcm43xx broken with 2.6.20.8 kernel https://launchpad.net/bugs/85099 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
