First get your machine back up and on the same network that you were before so you can get your skinernet back up bro then I'll try and help alleviate your problem.
I don't know exactly what ya did to lose your settings but first try getting your network settings back together:
You have a router so you probalbly use the private ip addressing that your router supplies via a DHCP feature built in. Make sure your network connection is set to obtain an IP address automatically. Then go to a command promt,(Start,CMD enter)
then enter ipconfig/release and enter. Then type ipconfig/renew.
See if that gets you talking to your router and the internet again.
