I bought the Amped Wireless AP2000G high power access point. You really do not need another router. An access point will do just fine, and will not have all the crap that a router has. My AP has been flawless and its high power now gives me coverage in all places of my home, which cannot be said for the the crap wireless support in the Verizon provided router.
I am, however, working on a problem with my setup and that is the use of the new FIOS Mobile app. Its supposed to allow you to watch live TV on your tablet of choice, but for some reason when I try to connect its telling me I need to be connected to my FIOS broadband router. Waiting for a response from Verizon on this.
