I tried this patch but it seems that this patch does not work. I applied the patch, installed the kernel and rebooted my laptop. After conencting to the AP and I wait for 25 minutes, then I start to ping my gateway. At exactly 30 minutes, it re-associates, and the network connection is lost for about 9 seconds: 64 bytes from 192.168.108.254: icmp_seq=116 ttl=255 time=1.84 ms 64 bytes from 192.168.108.254: icmp_seq=117 ttl=255 time=2.45 ms 64 bytes from 192.168.108.254: icmp_seq=118 ttl=255 time=8.38 ms 64 bytes from 192.168.108.254: icmp_seq=119 ttl=255 time=3.92 ms 64 bytes from 192.168.108.254: icmp_seq=120 ttl=255 time=5.33 ms ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable 64 bytes from 192.168.108.254: icmp_seq=131 ttl=255 time=4.90 ms 64 bytes from 192.168.108.254: icmp_seq=132 ttl=255 time=5.42 ms 64 bytes from 192.168.108.254: icmp_seq=133 ttl=255 time=2.38 ms 64 bytes from 192.168.108.254: icmp_seq=134 ttl=255 time=16.4 ms 64 bytes from 192.168.108.254: icmp_seq=135 ttl=255 time=29.7 ms You can see there is nine pings which produce "Network is unreachable" error. That's about nine seconds I suppose.
