Re: internet problems
The router is not assigning that computer an IP address. Log into the router and make sure it's setup for DHCP, and for more than one computer. Depends on the router for the admin username and password. If it is a cable modem, anytime you go directly to the modem from the PC, after removing the cable from the router, you should power cycle each- modem first, then router. This should give you a direct connection to the Internet. Hope this helps.
