Title:
  8086:4236 iwlagn kernel module must disable n-support to work with
  Intel 5300 wireless card

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  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
