A bisection led to this commit, which was confirmed by reversing the patch. The drivers can connect to a 802.11n networks, which is why the problem has gone undetected from kernel 3.10 till now. These drivers use the rate-control mechanism in their firmware. I suspect that this is causing the problem. What actions do the drivers need to take that were not required before this patch? Larry
