I run Windows XP home. My 3 yr. old ASUS M2N motherboard fried and I replaced it with an ASUS M4N78 Pro. Instead of doing a fresh install of windows, I plugged my old harddrives in and prayed it would boot to the OS. It worked fine except for this problem. I use a Pantech USB 150 wireless modem from Verizon in my desktop because I can't get cable and satellite is too expensive. It worked fine with the old MB. Now, my computer sporadically drops my connection and 'redsicovers' the modem as well as the belkin USB hub it is plugged into. I tried to plug the modem into the motherboard USB port in the back but that actually made the problem worse. 5-10 seconds after I connect, my system would drop the connection. I plugged it back into the belkin usb hub and I may work for 10 minutes or an hour, then it will suddenly drop it again and rediscover the ports again. Something else, these LAN connections(#6,7,9,12, ???) keep popping up saying there is a network cable unplugged. Right now in device manager, under modems is: Pantech usb modem #14, under Network Adapters is: Pantech usb modem wwan driver #14 and under Ports is Pantech usb modem serial port com32. The modem, driver and LAN numbers keep changing each time the connection is dropped and the ports/modem 'rediscovered'. I know this is long winded, but I'm trying to give as much info as I can. I haven't done anything yet, hoping for an answer here.
