Windows XP System with IE 7 and Firefox 5.0. I cannot get on the Internet. I have an active and legitimate IP address - 192,168.1.2 - and I can ping web sites successfully by their FQDN and by their IP address but if I try to get there using a web browser I get the wonderful "Page not found" error. I have checked proxy setting and there are none and I have reset all defaults with no luck. I have reset the modem and the router but the problem persists. What am I missing? What could possibly be the problem?
