This network is at my school (many access points). My school also have a unsecured network and this network works perfect (many access points too). -- NetworkManager causes system freeze, lock up, kernel panic https://bugs.launchpad.net/bugs/336001 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
