Bug Description
After upgrading from Ubuntu 11.10 to 12.04, wifi connected properly but the connection was dropped again after only ~5s. the problem seems to be related to IPv6. Disabling automatic IPv6 configuration in NetworkManager (see conf file option below) solves the issue for me:
/etc/NetworkMan
