Version Ubuntu 11.10
802.11-n support is not implemented fully. enabeling it (as Ubuntu does by default) causes the driver for the wireless card to struggle, every 30 minutes or so, the wireless network drops your connections, and promtes you for password, and all sorts of fun things start happening.
disable the 802.11-n support by passing this option to the driver
echo "options iwlagn 11n_disable=1" > /etc/modprobe.d/iwlagn.conf
should fix the problem
