I just fought through literally and hour and a half of "Activation (wlan0/wireless): association took too long.", made worse by keyring problems that cause each failure to produce a prompt for the key (not the subject of this bug, that's unrelated.) Adding
[ipv6] method=ignore as suggested above to /etc/NetworkManager/system-connections/Auto XXXX (ssid elided as I'm a guest here) and bouncing NetworkManager to make sure it reread the file (for about the 10th time) immediately stopped the spinloop... so this probably deserves more attention. (The local wifi is WEP with a hex key, on a WRT-54G running factory firmware, which worked fine when this laptop was running Oneiric.) (local system is an x220t) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/997056 Title: WiFi disconnects shortly after connection established To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/997056/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
