OK, its not a problem with the PC then, its a router and or modem problem. Is it a combined router modem or is the router yours? It's a combo unit and supplied by your ISP its time to call them. If its your router you'll have to bypass it and connect directly to the modem. It you then get internet its a router problem, if you don't you're back to calling your ISP. I have to go out for a while but will check back latter on when I'm home again.
