I was trying to change my IP address. I followed the directions from the official windows website

http://windows.microsoft.com/en-US/windows-vista/Change-TCP-IP-settings

And now I'm unable to reconnect to the Internet. I'm on a wireless router, and i've tried resetting the router.

(to answer your immenient question as to how I'm posting here, I'm posting from an iPad.)
Any ideas as to how I can reconnect to my wireless?

Set you computer back to DHCP.
