bcm43xx: firmware needs to be cut again if user upgrades kernel

Is there a way to store the firmware file(s) in such a way that the upgrade won’t ignore the currently installed firmware (installed via restricted manager) ?

I have set linux-restricted-modules-2.6.22 as a possible "also affected" package. Restricted-manager should not really care about the firmware once it is installed (in Ubuntu). Please change the package if you feel that it should belong elsewhere.

linux-restricted-modules-2.6.22 does not contain any files related to this bug.

The fix would be to make sure restricted-manager downloads the firmware to /lib/firmware instead of a subdirectory of /lib/firmware. If someone's feeling industrious, the file to change is /usr/lib/python2.5/site-packages/RestrictedManager/handlers/bcm43xx.py . But beware that right now restricted-manager writes a fake bcm43xx_microcode11.fw file into /lib/firmware.

Why is this on wishlist? This is a serious bug if you ask me.

i thik this is a big problem and it should be a bug

Martin,

The following does the trick for me:

sudo cp /lib/firmware/`uname -r`/bcm43* /lib/firmware

This must be done after having installed the firmware via the Restricted Driver Manager.

Good Luck,

restricted-manager has been superseded by 'jockey' in Ubuntu Hardy (a complete redesign and rewrite). Juggling tasks.

jockey uses b43-fwcutter now, which puts the firmware into a kernel ABI independent directory.

I experienced this problem exactly. When I tried to use the hardware drivers utility it attempted to re-install the restricted driver. It first tried to download a file. It failed and froze/crashed. I then found a set of instructions at http://www.linuxwireless.org/en/users/Drivers/b43#devicefirmware This got my wireless back but I am unable to actually connect to a network (although I think my internet [here at school] might be down). Not really sure.

This morning I downloaded "Windows Wireless Drivers" from the add/remove applications. I restarted and without doing anything to restricted drivers (I don't even have it anymore for some reason) I have wireless again after restarting. I don't really know why it worked or if it will work with other machines but all I know is that I got ndiswrapper to work for a 4306 under 8.04 using nothing but add/remove applications.

My Wlan, Broadcom on HP-Mini 2133, works with no restricted driver on 2.6.27-9 out of the box
after upgrade to 2.6.27-11... no Wlan exist.. only I see me card by "lspci"
Broadcom Corporation BCM4312
When I boot in to the previous Kernel (2.6.27-9), works fine...
