|Well, first off the wireless card must be a Belkin pre-N card or else you wil not be able to get it to work. If it is, I'd suggest going to the manufacturer's site (or tech support for help).|
In any even - it won't make any difference! Since the other computer is not using a Belkin Pre-N card and your internet connection is under 10Mb/s that extra bandwidth can't be used anyway. Even if the other computer was also Pre-N and both shoed 108Mb/s you wouldn't be able to use all that bandwith just transferring files between the two computers because your hard drives can't push data that fast.
