I recently upgraded to the Verizon FiOS Quantum service 75/75 speeds. Verizon had shipped me the new quantum router but I already had two Airport Expresses. I have my main Airport Express base station connected to the FiOS Lan port and into the WAN port on my Airport Express. I did this along with Double Natting so my Aiport network would allow me to add the Guest Wireless feature. The second Airport Express is joined as a client so I can hard wire a PS3 that only has G wifi speeds. When I perform speed tests connected to my Airport I get ~50 down and ~30 up. However if I enable wireless on the Fios Gateway I can get speeds around ~80 down ~45 up. My question is does the Airport Express routers just not have enough power to handle higher download speeds. Is double natting messing anything up? Should I ditch the Airports and just use the FiOS router?
