Netgear WNR2000 v3

So my house has Verizon Fios, that comes with an wireless internet router, but frankly it is terrible. so to solve this we bought a netgear router. Which has worked great for about a year now, my father got a new computer with a network usb device and it said to connect to it he had to push a network button on the front of the Netgear device. Once we pushed it, he connected with no problem.
The only problem is then each computer in the house after that to connect we had to push the connect button on the netgear box.

The computers are not the problem, however my xbox360 on the other hand can now no longer connect to the network saying i need a wpa2 password to connect. Ive done all the internet tutorials where i go online type in 192.168.1.1 and all that jazz but everytime it picks up the fios router, not the netgear router. even when the netgear router is the one directly plugged into the computer.

i sadly do not have the option of plugging the xbox directly to the internet please help haha thank you CHEERS!
