My brother bought a new computer and I set it up for him at my house (installed windows xp, made sure all drivers were up to date, etc), but then when I took it to his house and connected it to his router, it can't locate the internet.  I tried using the "repair connection" function, but that didn't work.  When I had it at my house and connected it to my router it worked FINE.  I'm wondering if that is maybe the problem, did connecting it at my house maybe cause some IP address conflict?  His PC has a wireless card but I haven't installed it yet because I wanted to make sure he had a connection when hardwired before I tried setting up the wireless.  How can I repair the connection besides using the "repair connection" button? You need to reboot his network.

Turn off the modem...turn off the router.  Wait 30 seconds...turn on the modem...wait till it's ready...then turn on the router...let it cycle.  When complete...reboot computer.Thanks, I'll try that tonight.OK, tried it, and it didn't work.  I'm still getting the "limited to no connectivity" message.  First I tried doing what you said, turned off everything, then reconnected the modem, then the router, then turned on the pc, same error.  Then, I reset the pc gateway to the default, per the instructions in the network help WIZARD to 192.168.0.1 (it was something else, but I don't remember what at the MOMENT), rebooted the pc, and still same error.  Then I tried installing the router software since this was a new pc and it told me to basically do the same steps you did, and for a second I thought it was going to work, it was actually looking for a connection instead of just giving me the connectivity error, but then, after a few minutes, it did anyway.  I also, per the network help wizard, tried doing the "ipconfig /renew" in the command prompt, and nothing.  This is really driving me crazy.  The weird thing is there is another computer in the house and a PS3 that are both using the same internet connection and are both functioning properly.  What's the deal?Anyone...? Do not know if you have solved the problem yet. but you can go into the internet options then connection and check to see if there is anything in the dialup and VPN settings box. If so remove it and make sure that there is no LAN settings checked also. then try to RUN the wizard again.
