Added new cable modem, new router, and three machines to the router. First PC is hardwired to the router and it functioning perfectly, second machine (a laptop) is connected and functioning perfectly. The third PC is the problem. The wireless connection is successful on the third machine, and you can successfully ping the router; however, going beyond the router is the problem. Additionally, in order to make the connection to the router, I had to manually input the ip information. For some reason dhcp is not functioning correctly on the machine. The pc is running XP SP2 and has been patched. Additionally, firewalls have been turned off. The cable modem, router and machine have been refreshed by powering off and on in order (too many times to count). Any thoughts on what could be happening?
