Do Routers Have Modems Built-In?

Are Modems Integrated into Routers?

Routers and modems are two separate devices.

A modem device can connect to a network. It can convert digital signals into analog, whereas a router, on the contrary, connects with the modem and allows for different devices to connect with it by becoming an internet hub.

A router can sometimes have a modem built-in inside of it.

Nowadays, there are many ISP that are offering routers that have both the functions of a router and a modem. These routers are known as “Gateway’ or “Modem Routers.” They make things easier for a user to connect to an internet network.

So, instead of paying for two devices and combining them, the users can now have a modem router with a cable-wired connection.

Moreover, it can allow smartphones or other similar devices to be connected to it due to built-in router functions.

Is it Essential to Have a Router with a Modem?

A modem and a router are essential to establish a reliable, safe, and stable internet connection.

However, if you have a combo or a modem router, it would be enough, and there is no need to buy a separate router or modem. These routers can work as both a router and a modem for a wired internet connection.


Most routers work as “Modem Routers,” which have the facility of both modems and a router. They allow users to connect to the internet through a wired or cable connection. Many others still need this built-in feature to work on both devices. These are standalone routers and do not have modems.
