So I'm a total idiot. I followed all the instructions to change my IP, but only after I completed the process did I realize that it wasn't meant for people getting their internet through a router. Now I don't know how to get the IP back, and my internet connection has been severed (I'm on a friend's laptop).
What do I do to fix this?
First step will be to make sure your Network Card is set to DHCP. You can follow the steps in the change IP instructions to get to the Network Card properties.
If it is not...make sure it is set to DHCP.
At that point, you can then either reboot, or do an ipconfig /release and an ipconfig /renew. See our [URL="http://www.whatismyip.com/faq/dos-windows-ip-commands.asp"]IP Command[/URL] page to learn how to do this.
Does your internet work after performing these steps?
