Dvanzo, Stanislaw Gruszka doesn't work for Intel, so his claim it's not
supported is baseless. Hence, as far as Ubuntu and upstream is
concerned, you are supported. With this in mind, please follow all of
the instructions noted in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002884/comments/8
and we can take it from there.

Title:
  Slow 3945abg - 12.04

Status in The Linux Kernel:
  Expired
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi!,

  I was suffering slow wifi transfers with my Vostro 1500 (Intel
  3945abg). 10.04 was ok, but since then, no mather what, the speed has
  been awfull. Recently upgraded to 12.04, but no-luck. Transfers
  between 40KBs and 70KBs... Wired connections to the same router allow
  me to connect up to 320KBs.... I already did everything a could
  without success... You can see previous info at bug #621265

  My info:

  uname -a
  Linux Vostro-1500 3.2.0-24-generic-pae #38-Ubuntu SMP Tue May 1 16:40:26 UTC 2012 i686 i686 i386 GNU/Linux
