Problems installing a wireless router

I purchased a new Linksys wireless router and am not able to get past the install screen. It gets to step four of four and errors out saying "no router or gateway connection". This error is stated all over Google but no one seems to have a definite answer. The instructions are very basic. I thought I would reach out to MajorGeeks for advice before contacting their support line. Thanks in advance.

 

Perhaps you could provide the model number?
