Hi,
There are a few things i would try / check
1. what the signal strenght if the wifi signal?
2. download and use a Linux Live CD and connect to the wifi network and do a speed check, this will test the wireless card itself, if it still only gets teh slow speed then its hardware related,
3. are there any cordless phones or radiators near the antena of the wireless card? these can cause signal issues
