well downloading is almost always at your max bandwidth cuz u can download from many sceorces untill you reach your max. so the only thing i can think of is go to tools>options>downloads. there you should find a speed adjuster for downloads. im pretty sure that max is default so after that try: tools>options>speed. there you can set L/W for either: dialup, cable, t1, or t3. make sure this is set correctly. other than that i duno what u can do
