LAN Connection has limited connectivity
My father recently got high-speed cable and the cable modem is setup right next to the computer and then was connected to the computer with an ethernet cable. Everything worked fine. Then they bought a laptop and a wireless router to use with the laptop. Rather than start the wireless router install on the laptop, he inserted the router's CD in his computer and started the install (while also unplugging his ethernet cable and attempting to add the router). When he realized he should really be doing this on the laptop, he stopped everything and plugged the computer's ethernet cable back into the cable modem. However, the computer now cannot connect to the internet.
When I go to Network Connections, I see that Local Area Connection says "Limited Connectivity...etc.". The cable modem appears to functioning properly (all lights are blinking green, etc.). I have disabled and enabled Local Area Connection and rebooted along the way hoping it would fix itself, but it doesn't. I selected Repair and it says it can't repar the connection because it can't renew the IP address.
I'm guessing that starting the wireless install changed some network settings, but I'm not sure what. Please help.
Thanks!

Did you reboot the modem? If not, it's cached the MAC from teh first connection.... Try rebooting it if you havent.....

Yes, I haved turned it off and on. Is there more to do to reboot it? Should the PC be on or off when it reboots?

That's it... we weren't leaving it off long enough. We unplugged the cable modem for 5 minutes and turned everything back on and it worked.
Thanks!
Thanks!
