Done Package network-manager is not installed, so not removed The problem only happens occasionally, and lasts for 1-15 minutes before correcting itself. -- Wireless connection frequently drops [deauthenticating by local choice (reason=3)] https://bugs.launchpad.net/bugs/548992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
