I have the same problem on 3 separate ThinkPad laptops. All use various current Intel cards supported by iwlwifi driver (eg, Ultimate N 6300). Problem happens when connecting to any WPA encrypted WiFi. I have tried Cisco enterprise grade APs, Linksys home APs with original firmware, Netgear, and Buffalo with OpenWRT. It doesn't stay connected for more than a few minutes without getting that message. Problem occurred on Ubuntu 12.04, and also on Linux Mint 12, Mint 13 and Mint-Debian (current). WEP encrypted connections were not affected.
I was able to resolve the problem completely by uninstalling Network Manager and switching to the "wicd" connection manager. This resolved it on every one of the laptops, despite the fact that they use different distributions. I haven't posted my dmesg since it looks just like the original poster's output, apart from the wifi driver. I believe it to be an issue with WPA handling in Network Manager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/953631 Title: Regular Wirless Network Disconnects - wlan0: deauthenticating by local choice (reason=3) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/953631/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
