I'm searching for a G1100 router on Ebay so that I don't have pay Verizon $199 for a new one. [FYI: I prefer to connect through coax so the router has to be a G1100] However, whenever I find a reasonably priced router it seems to be either a Frontier model or one loaded with Frontier firmware. Are these Frontier routers compatible with Verizon Fios?
