Dvanzo, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.12

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

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
