Bug Description
I was suffering slow wifi transfers with my Vostro 1500 (Intel 3945abg). 10.04 was ok, but since then, no matter what, the speed has been awful. Recently upgraded to 12.04, but no-luck. Transfers between 40KBs and 70KBs... Wireless via another client transfers at 600 KBs. Wired connections to the same router allow me to connect up to 320KBs.... You can see previous info at bug #621265
WORKAROUND: ndiswrapper works better: 158 KB (1.27 Mbps).
