Quick update... I have been using a mainline kernel and it has seemed to be working ok for the past few weeks. I saw the Ubuntu kernel was updated to 3.11.0-18 so I have been trying it again and it seems to be working some of the time as well. Today, after resuming from suspend, the wireless was connected according to nm-applet, but I was unable to ping the local network. Using nm-applet, I turned off wifi and turned it back on, and after connecting, I was still unable to ping. After about 45 seconds, the network started working again. The kernel log shows nothing during this time.

If I can connect, it seems to work fine indefinitely, but initial connections (after suspend, or right after a reboot) only occasionally works. Sometimes, if I wait long enough the connection starts working after several minutes, sometimes it works if I turn off wireless and turn it back on, but often it just never works. According to dmesg, iwlwifi is associating with the access point just fine, but if I ping the ap, I get "netowrk unreachable". WORKAROUND: 11n_disable=1 After associating, dmesg report: # dmesg |tail [101704.467324] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S [101704.474053] iwlwifi 0000:03:00.0: Radio type=0x0-0x3-0x1 [101704.621429] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [101704.717787] wlan0: authenticate with xx:xx:xx:xx:xx:xx [101704.780532] wlan0: send auth to xx:xx:xx:xx:xx:xx (try 1/3) [101704.793246] wlan0: authenticated [101704.797390] wlan0: associate with xx:xx:xx:xx:xx:xx (try 1/3) [101704.798226] wlan0: RX AssocResp from xx:xx:xx:xx:xx:xx (capab=0x1011 status=0 aid=1) [101704.802300] wlan0: associated [101704.802347] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready But network is unreachable.
