WiFi not working - wlan0 FAILED

My Arch (3.6.5-1) is exhibiting a rather peculiar problem: when wifi is set up, all logs indicate that the setup was successful and that the interface is up and functional. However, when attempting to access a website (or execute ping) all requests time out (despite that connection is reported as working and signal at 63% strength). This tends to happen randomly after laptop is switched on - after some time the connection usually starts working and does not break until next shutdown/suspend. Relevant dmesg entries (full dmesg output can be found [here](http://pastebin.com/PH7jb8fy)) : [ 13.858528] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 14.024275] r8169 0000:02:00.0: eth0: link down [ 14.024339] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 34.895920] wlan0: authenticate with 00:24:6c:c8:e4:a1 [ 34.900827] wlan0: send auth to 00:24:6c:c8:e4:a1 (try 1/3) [ 34.902963] wlan0: authenticated [ 34.908362] wlan0: associate with 00:24:6c:c8:e4:a1 (try 1/3) [ 34.911153] wlan0: RX AssocResp from 00:24:6c:c8:e4:a1 (capab=0x1431 status=0 aid=9) [ 34.911217] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 34.911294] wlan0: associated ip -s link shows: wlan0: mtu 1500 qdisc mq state UP mode DORMANT qlen 1000 link/ether 50:b7:c3:1e:f4:21 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 14970982 50472 0 0 0 0 TX: bytes packets errors dropped carrier collsns 19116 233 0 0 0 0 ip minotor outputs some failure messages: [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [LINK]3: wlan0: link/ether [LINK]3: wlan0: mtu 1500 qdisc mq state DOWN link/ether 50:b7:c3:1e:f4:21 brd ff:ff:ff:ff:ff:ff [LINK]3: wlan0: mtu 1500 qdisc mq state DORMANT link/ether 50:b7:c3:1e:f4:21 brd ff:ff:ff:ff:ff:ff [LINK]3: wlan0: link/ether [LINK]3: wlan0: link/ether [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [LINK]3: wlan0: mtu 1500 qdisc mq state UP link/ether 50:b7:c3:1e:f4:21 brd ff:ff:ff:ff:ff:ff [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]ff02::2 dev wlan0 lladdr 33:33:00:00:00:02 NOARP [NEIGH]ff02::1:ff1e:f421 dev wlan0 lladdr 33:33:ff:1e:f4:21 NOARP [NEIGH]ff02::16 dev wlan0 lladdr 33:33:00:00:00:16 NOARP [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.79.218 dev lo lladdr 00:00:00:00:00:00 NOARP [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [LINK]3: wlan0: link/ether [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED [NEIGH]144.32.78.1 dev wlan0 FAILED All that should be loaded seem to be ([output of lsmod](http://pastebin.com/zJm1NiX9)) . Any idea on how to solve this or what the problem is?
