I am having trouble with a modem that stops responding for no apparent reason. Sometimes it will stop right away and then others it can go for hours. The little icon on the task bar shows that it is still logged onto the internet and the send light on the Icon flashes from time to time but the recieve doesn't. But sometimes when it does this if I go to a completely different site it will start working again this is only occasionally. I have a US Robotics modem with all the latest drivers and updates. I contacted my ISP thinking it might be a settings issue and they walked me through everything and it is still doing the same thing. Then I contacted US Robotics Tech support and we went through the same thing and could find no problems. I finally thought it was the Modem hardware itself so I returned it and purchased another modem of the same make and model and it too is acting the same way. Is there anything else that I am forgetting. It is becoming a chore to disconnect and redial everytime this thing acts up. I am running a Pentium 4 1.7 Ghz with 384 megs of ram my modem is a US robotics model 5610b. Any help would be greatly appreciated.
