Comment 1 for bug 728746

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
>>
