"No Internet Connection is Detected" Help!

I have a Netgear RangeMAX Duo Wireless-N Router WNDR3300.

In the middle of the day today my internet stopped working. If I switch to a wired connection I can access the internet (like now). In addition I have two cables that both work.

When I plug in the second cable from the router to the computer I cannot access the internet and when I try to log into the router I get this message:
"No Internet connection is detected, the router cannot check the NETGEAR server for updated firmware. After setting up your Internet connection, go to the "Router Upgrade" page to check for updated firmware."

Essentially there is no way to get a connection through the router. I have tried a soft reset and a hard reset. I cannot figure out what is wrong with my router. I would really appreciate any help.

Thanks!
