Computer replaced - what do I need to do?

Hi,

My main PC (Windows 7/Dell) died with a hard drive failure.

It will be replaced in a couple of days.

I have all of the login information for my M1424WR fios wireless router that I set up and configured using that computer.

What do I need to do when I get the new computer?

I have the network cable (leading to the router) unplugged.

Do I just plug it into the new computer?

TIA,

Matt
