The brcm80211 driver, which is under GPL, replaces the non-free broadcom-sta aka wl driver. > Since there is no other clue in the logs, I turn to this list for > advice on how to proceed on this issue. You could try blacklisting the brcm80211 driver, so that the wl driver will be loaded instead. To do this, run: echo blacklist brcm80211 > /etc/modprobe.d/brcm80211.conf Then switch to the wl driver: rmmod brcm80211 && modprobe wl If this fixes the problem then we know that this is really a bug in brcm80211.
