I have the USB760 and have had great reception with it ever since i've had it; up until now. I recently moved into a new city that is 4 miles outside of the "broadband" coverage area. I can still connect with my USB760 and browse, but its as slow as dial-up. Would one of the external antenna's, and/or amplifiers virtually bring me closer to the broadband coverage area? or would it be a waste of money and patience? Or should I just get out of my contract and go with the town's dsl?
