I purchased a wireless router a few months ago and use it with the comcast service i have now. I'm thinking about switching to FIOS but I want to keep this router since I just bought it. Can I keep it or do I have to switch to a Verizon router?
the verizon router must be in place if you have TV with verizon too.
Their Video On Demand, Program Guide and Widgets system all work through the internet, and they are delivered over coax to a router that is MOCA. their router that they give out is pretty much the only moca router out there, so it has to be there if you have TV with verizon.
That does not mean that you can't use your router with it, it just means that you would have two routers working at the same time, which a lot of people do. The easiest way to do it is to plug your routers wan port into a lan port and make sure your default ip address for your personal router is anything other than 192.168.1.1, so your personal router should be 192.168.2.1, or 3.1, or 4.1, anything but 1.1 or here are some advanced configurations if you're a DIY kinda guy.
