I have the exact same problem on IBM Thinkpad x201 with Intel iwlwifi driver using open wireless N access point. It usually takes one resume cycle for the bug to appear. The network manager shows the wifi access point as connected. However, once this happens the laptop wireless netwroking completely stops, can't ping anything after. The only way to resilve this is to reboot the computer. Switching the wireless on/off in network manager does not help, restarting the network manager does not help.

I have also tried every kernel version (3.2.x, 3.4.x and 3.5RCx) with no success.
