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. -- [iwlagn] networkmanager applet cannot connect to WPA2 home network (intel 4965) https://bugs.launchpad.net/bugs/348275 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to plasma-widget-network-manager in ubuntu. -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
