One possibility might be that you've somehow got yourself connected to the WAN side of your router, rather that the LAN side. I think you should login to your router and see what the address of the Internet Port is. I seem to remember that happening to someone here with one of those "captive" or ISP-managed modem/routers. It's one reason why we run three routers at home: one that Cox rent, the real one (mine), and one with a broken WAN port that we use as a switch and wireless repeater. Cheers, David.
