You know, you've not even bothered to say what your modem/connection is so how do you expect any kind of sensible answer?
Anyway, here goes nothing, try TweakMaster, an Internet Optimiser, it may help:
TweakMASTER - The Supreme Internet Optimizer Paledroses17
TweakMaster (free version) helped stabilised my son's wireless connection to my modem, so it just might help your wireless connection problems as well.
