I have a network with 2 computers on it. The first computer is connected to a 2wire homeportal modem/router by a USB cable. The second computer is connected through the phone line to the modem/router. The other day the first computer has quit connecting to the net. I have run several tests, uninstalled/reinstalled, and contacted tech support. What I have found is the network adapter has a default IP address that windows gives it. I have tried to release and renew the IP through winipcfg and commands in DOS but the IP does not change. Any suggestions would be greatly appreciated.
