broadcom 80211 firmware needs symlinks

I confirm. For the brcm80211 module, it is necessary to add links:
<<
cd /lib/firmware/brcm
sudo ln -s bcm43xx-0-610-809-0.fw bcm43xx-0.fw
sudo ln -s bcm43xx_hdr-0-610-809-0.fw bcm43xx_hdr-0.fw
>>
And do this command if wl run :
<<
sudo rmmod wl
>>

And this commands work :
<<
sudo rmmod brcm80211
sudo modprobe brcm80211
>>

Thanks for confirming, Mohegan. I'm setting the status to 'confirmed'.

It works but it is very unstable. I have many kernel panics with the brcm80211 module.

After creating the following symlinks

/lib/firmware/brcm/bcm43xx-0.fw
/lib/firmware/brcm/bcm43xx_hdr-0.fw

it works fine with BCM4313 wireless card on my Asus EEEPC 1015pem Ubuntu 11.04 64bit.

Mohegan: you should probably file a new bug for your stability issues. File it against the 'linux' package. You could include the output of lspci and dmesg.

Ok, I create this bug report : https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/730215.

The workaround partial works on Lenovo IdeaPad U160. After creating the symlinks, the wireless device is discoverable. But, when wireless is enabled by any method (selecting Enable Wireless in network manager, rfkill unblock wifi, keyboard shortcut) Natty immediately freezes and requires a hard shutdown

This bug was fixed in the package linux-firmware - 1.49

This update enabling the open source brcm80211 driver works, but is extremely unstable on my system. I can last only several minutes before a kernel panic occurs. I have to blacklist the brcm80211 module and reload the closed wl module. The brcm80211 seems to take precedence over the wl, which I already had installed. This will definitely present an issue for the common user. I have a Broadcom 43225.

James: thanks for taking the time to report the stability issues you're experiencing. Could you please report them at #730215, or click the 'affects me too' button, there. You can also subscribe to that bug to watch its progress.

This bugreport is just about the firmware symlinks, and will probably be closed soon.

Hi i have a Dell Latitude D620, the wireless does not work at all. From what i can tell my wireless is as follows:

0c:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 01)

The restricted package is installed an is reporting active according to the Restricted Drivers application.

My wireless functioned wonderfully in the previous release of Ubuntu (10.10).

Matthew,

I had same issue on my Dell Latitude D830 (same wireless card, etc)..

remove the STA restricted driver and then install the fwcutter method described elsewhere here (just google BCM4311 fwcutter install.

Then do a:
sudo modprobe b43

Presto, wireless working!!

Worked for me, hopefully for you too.
