  8086:4222 [Dell Vostro 1500] 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:
