Thanks for your fix. I have two questions:
1.) Is this fix part of the upstream linux kernel or only ubuntu specific? If not: Will this be pushed to upstream and in which kernel version?
2.) Does it fix the related bug for the iwl-1000 wifi interface (part oft my Lenovo edge e320), which has similiar symptoms on multiple access points with the same ssid (eduroam network)?

Bug description:
  The connection slowly degrades until dropping.  Disabling 11n seems to
  workaround the issue.  With the last disconnect, the following
  messages were in dmesg:
