If you are using the fios Quantum Gateway Router you should have the ethernet in the WAN port on the fios Gateway. You then place the Netgear into access point mode in your routers settings. After you turn on access point mode on the Netgear take a ethernet cable from the FiOS Quantum Gateway LAN port and plug it into the Netgear WAN port. You now get DHCP from the verizon fios router, but everything else is assigned from the Netgear router.
its a good idea to enter the verizon gateway router and turn off the crappy wifi and make sure the wifi is enabled on the Netgear.
