Touch Pro slow Internet Sharing :/

[Packerfans1]

My internet sharing is really slow. By slow I mean slow(slower than my high speed, my ISP sucks so yea their "high-speed" is about dial-up) Anyways, anyone know a fix preferably a quick one. I have Alltel (not sure of ROM or Radio Version) It's stock so yea... so if anyone knows like a faster radio for it or w/e please post. By the way I have a fairly good connection to the network ( I've tried it other places but it seems just as slow) :/

Thank You!!
