Gonna have to check the router configs. Since this is a verizon router you may want to contact them before you have a go at it yourself. I am no incredibly familiar with this unit so I'm not sure on all the details, so it could be 100's of things.
Another solution may be to install a wireless access point on one of the data ports, and config that yourself. You should be able to pick up a cheap wireless N for around 50 bucks.
I'm sorry without sitting in front of your router and computer that's the best I can offer. Sorry
