Its been a while since I have posted but I am stumped. My cousin has a XP machine with a built on motherboard network card that quit connecting. So her dad (they dont live at the same house) ask me to look at it so I added a PCI network card and quickly got it online at my house. (cable internet via router) so I thought it was fixed so I took it to my cousins dad and hooked it up to his internet and it does not read the Gateway when I do a IP config. It never connections. They have cable internet also and they never have a problem with their PC connecting. I reformatted their PC and reloaded XP and it will connect at my house but still not connecting at theirs. (they run straight off the modem they dont use a router) still the gateway is undetected they do get a IP address and a subnet mask. I have checked to automatically check the gateway in the advanced properties. I tried manually entering a gateway address but still not connecting. Any suggestions. Thanks. Oh one thing Im going to try is a different network card. However if it works at my house it should work at theirs. Thanks again.
