Since this item is a modem as well as a router, a separate modem is not necessary when using CenturyLink High-Speed Internet service for access to the Internet.
Yes. The modem connects to the service provider (plugs into the phone line for DSL, connects to cable line for cable internet). The router spreads the internet connection from the modem to other devices through Wifi.
This particular product is a combination unit. It is a modem and router in one device.
To use your existing router, all you need is a standard modem that is compatible with your service provider, and plug your router into the modem's ethernet port.
If you only have 1 computer and do not need Wifi for other devices, you do not need a router. A standard modem will do just fine.
