my wireless is very slow

[debian]

hi all

i got my wireless device to work (linksys WUSB54GSC) using the rndis 
wrapper  (not to be confused with the Ndiswrapper, which didnt work with 
my card, i tried the drivers from the cd and the downloaded drivers, i 
even found a guide which told me how to install the drivers on the 
ndiswrapper, but they didnt work). But i can only get 39k max download 
speed from it. My router is a 1.5mbit and the max i can get out of it is 
165k. So what do i do to achieve that speed with my wireless?
