how can i connect my Panasonic Viera Link TV with Airport Extreme?

I use the Panasonic adaptor that came with my Blu-ray player. It worked with my Panasonic plasma TV when I used a NetGear router, but I recently changed to an Airport Extreme router and now neither the Blue-ray nor TV will connect. They find my network, but when I enter the password, after waiting a while, I get an error message that the network timed out. My iPad, iPhone, and MacBook Pro and MacAir all connect fine to this router from anywhere in the apartment. I am not using the wrong case when entering the letters of my password. It's exactly the same passsword that I enter on all my devices. Please help me connect the Panasonic TV to the Airport Extreme--I do NOT want to use ethernet. I want to use the wireless connection. Again--it worked fine withe the Netgear router, but does not connect wiht teh Airport Extreme. Thanks!
