My dmesg log shows quite a lot of error messages (approx every 7 seconds in idle and more often when traffic is high): [ 4015.044435] b43-phy0 ERROR: PHY transmission error [ 4021.910720] b43-phy0 ERROR: PHY transmission error [ 4028.866892] b43-phy0 ERROR: PHY transmission error Thanks for your efforts to get my hardware working!
