i used to have a us robotics 33.6 sportster modem and didn't experience any abrupt disconnection with my ISP. i recently bought a 56k version of the modem and now i experience annoying disconnections from my server. how can i solve this problem?
First as Jerry said, try a different number. If you get disconnected on that number also, then check in DUN, and Control Panel under modems, and make sure that "disconnect if idle after x minutes" is not checked. If neither of these work, you might want to try reinstalling TCP/IP, under control panel, network.
