I have Intel 5300 card. It works fine with 3.2.16. When I try 3.3.6 or 3.4.0rc6 I get connection drops often - once 5-10 mins. With 3.2.16 such disconnects happen once-twice a day. AP - ath9k based router and it doesn't change. I'm using kernels from ubuntu kernel ppa. Here is what I see in logs during disconnect: [ 1024.296004] ICMPv6 RA: ndisc_router_discovery() failed to add default route.
