A:Answer I'm assuming the network extender for Verizon is to increase you cell coverage at your location, thus the calls are going over VOIP. You don't use Y cables in networking. They reduce traffic speed and other problematic issues. All you need is the modem, WiFi router with at least 4-5 ports and if you need more ports, then that is what the switch is used for. Most modems now a days have the routers built into them. The switch is what controls the flow of web traffic to each device, the router assigns the IP addresses & manages the web traffic, and the modem connects you to the internet.
