I use the UM 175 Pantech Modem plug and go from Alltel/Verizon - No at work I have absolute no problems with it. Everything works fine. I then go home and I have all kinds of problems. It kicks me off the internet, and if it does let me stay on it has a yellow exclamation marke on the connect at the bottom right. I have 1 less signal bar at my house than I do at the office (5 bars at work 4 bars at home) Our cell phones work great at home. Please help!!!?
