I'm not sure what advantage you would get by adding another router. Adding a second router really complicates things. If the FIOS modem were separate from the router then you could just disconnect their router and replace it with the WNDR4500. Or as another gentleman said, you could put it in Bridge mode but you will be slowed down to FIOS router's speed and not gain much having this new one. I hope this helps.
Hello, I honestly don't know... I had someone hook the router up there for me... there is a phone number on the box or on the papers that came with your router there... you can always give that a call so you can get the right answer to your question. The phone number I have is: 1-888-netgear hope this helps.
Yes, you can. I've been doing it for several years with my FiOS Actiontec router (wireless turned off, DHCP turned on), and a Netgear wireless router (wireless turned on, DHCP turned off). Connect the wireless router to a LAN port on the FiOS router, configure as above, and you're good to go.
You would have to read this article: http://www.dslreports.com/faq/verizonfios/3.0_Networking Depending on what you do with your FIOS you would need to choose appropriate installation option. There are many reasons to get a third party router with FIOS. Most FIOS routers are only 801.11G (slower throughput between connected devices on the same network). You also might want features that you might not be getting with Verizon router.
You should be able to log into your new router (make sure the ip of the fios router and the netgear one is not the same or you will have a problem when trying to log into one or the other) and turn the DHCP setting off because if you are plugging this router into the back of the fios router, only the one with the main connection (fios router) should be assigning ip addresses for your devices. This is the only thing you should have to do to get it working correctly if you are just plugging it into your fios router for a better signal or something. If you mean using it as a signal extender, I don't really know if you can do it on this router, but you can look for a setting that says "use router as a wifi repeater" or something similar to that.
Hopefully I helped some. [EDIT] You will also want to turn the wireless radio on the fios router off if you are just plugging the new router into the fios one. When connected to your new router, if you enter the ip address of your fios router, you can still get into its settings page and functions.
