first of all, from my experience, u must place ur antenna where u can get 100% signal constantly, meaning not like 90-100%, it must always be 100%, and if it still doesnt improve, try locating ur modem and antenna near the window on the oppsite side of ur house. meaning, if b4 this u put ur modem on the window facing north, now change it to put near ur window facing south, ive tried that, and it really helps..... i know how u feel....me also had experienced the super slow connection of 5-20 kbps........and been working to overcome it, finally.....its getting better....
