    Frontier FIOS bought their FIOS network from Verizon FIOS and as such works the same way: they attach your WAN MAC to your client ID. If you try to swap routers without releasing the WAN IP, which in turn let's you bind a new MAC, the new router MAC will not match the existing bind and connection will eventually drop. So you have several options:

     

    1. If your existing router can release WAN IP, do it, disconnect the router, connect the new router and set the WAN to DHCP (or dynamic IP, depending on how it's labeled), and you're all set. The new router will get an IP and work as intended. This is the variant I prefer to use when possible.

    2. If your existing router does not have the option to release the WAN IP, write down the WAN MAC address and clone it to the new router MAC address. Disconnect the existing router, connect the new router, clone the MAC and you're all set.

    3. You can call Frontier tech support, tell them what you're trying to do, and if you're lucky and get to someone that knows more that to read a script, they will release the IP/MAC bind and let you bind the new modem to your account. I only use this option when everything else fails.

    4. Verizon has a software that you can run on a Windows PC, and through it you can unbind the connection and bind the new router. It's a wizzard type of thing, easy to use and it works fairly well. Not sure if Frontier is using the same software or not so you'll have to figure that out yourself.
