Tested with the lastest upstream kernel (v3.12) with no luck. The max
speed is 60 kB/s. My desktop speed tops at 730 kB/s.

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

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
