I am having trouble with my Acer Vista Laptop dropping the dial up connection. It has an Agere Systems HDA dial up modem. My old Win 98 desktop does not do this. The laptop worked fine with dial up for over a year, then suddenly won`t stay connected. It dials up, and stays on for a few minutes, then disconnects, redials, disconnects, and so on. I have had the phone lines checked, and am told that they are fine. After searching the net for possible solutions, I am wondering if the software for the internal modem got updated, or needs to be changed somehow. Can anyone help? Thanks, Doug
