Vish, ok so disabling n doesn't provide a WORKAROUND.

Regarding mainline testing, it would be best not to test the daily
folder, but the ones announced by Linus (ex. http://kernel.ubuntu.com
/~kernel-ppa/mainline/v3.12-trusty/ ). This is to avoid upstream
confusion.

As well, could you please provide the missing information following
https://wiki.ubuntu.com/Kernel/LinuxWireless#Debugging_information_to_provide_in_your_bug_report
? It is understood you don't have access to the router to change it.
However, as much information you can get from the router administrator
will be most helpful.

Title:
  8086:4222 [Acer Aspire 5670] iwl3945 resets wireless connection
  frequently

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The wireless connection keeps getting reset and it has become difficult to Skype or to watch streaming video from certain sites(comdey central or Hulu).
  This bug has existed for years, but I just havent gotten around to reporting it.

  Around the time when the connection drops I see the following
  messages:
