Title:
  Centrino Wireless-N 2230: 802.11n not working

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  802.11n networks don't show up in the network manager.

  Side note: With N-band enabled, i see a lot of "Tx excessive retries".
  When i disable N-band functionality, this is fixed and i get a lot
  more kB/s from it. That's why I currently have N-band disabled
  explicitly in /etc/modprobe.d/iwlwifi.conf.

  I'm assuming ubuntu-bug will have attached all possibly relevant
  files, so i won't repeat all my guessing here.
