Linksys Wireless Router :: WRT 610N Cannot Set Up Properly

I have a WRT610N V2 that I cannot set up properly.  The set up proceeds fine until the very last step when it cannot verify the connection to the internet.  Both my desktop and laptop show a strong signal from the router but neither will connect to the internet.Linksys support gave me instrucutions to set up the router manually, but I cannot access the router settings since it will not allow me to acess the internet to reach the settings site.
