I tried maxcpus=0 and verified that really only one cpu core is used but didn't help (so not smp problem). I realized that sometimes when I see connection interrupted, then after few seconds it recovers and network is again functional. 802.11n is disabled. One more thing, when i do "ifup wlan0" I get following output: NETLINK: Packet too small or truncated! 56!=16!=996 is it OK? Regards.
