I still have this problem on my Dell XPS M1330 with and without linux-backports-modules. For my case, removing iwlagn and re-add it solved the problem. I checked /var/log/wpa_supplicant.log and found
No configuration found for current AP.
When WPA2 joining is failed. When remove and re-add driver, this line never appeared again on the log.
