To enjoy a seamless Internet connection, it’s essential to know which device among the Spectrum-approved modems is perfect for you. Hopefully, this guide will help you choose the right one as per your Internet bundle.


What is the difference between a modem and a Wi-Fi router?

A modem connects you to the Internet whereas a router connects you to the Wi-Fi. Since Internet Service Providers (ISPs) rent both, users often confuse them to be the same thing.

Do you need a router if you have a modem?

No, you don’t necessarily need a router if you have a modem. A modem typically supports a single connection for a wired device.
However, if you want to go wireless and connect multiple devices to the internet, you are going to need a router. Routers connect to the modem through an Ethernet cable and pass the Internet connection to other devices over the wifi network.

Is a separate modem and router better?

Combo devices (a modem and router together) are space-efficient but it is recommended to use a separate modem and router. You enjoy better connectivity and fast Internet. You get access to features that can make your network trouble-free and flexible.

Combo units are powered by an AC adapter that eliminates the need for power cables. This is why they sound attractive. But they have performance issues that are most difficult to diagnose.

How do routers and modems work?

Router: It communicates between the Internet and the devices in your home to connect them to the web. It routes traffic between these devices and the Internet. Once the devices are connected to the network, it forwards data packets between them. The packets can be sent between devices and from the devices to the Internet.

Modem: It is to bring Internet service from the ISP into your home. A cable is used to form a connection. One end of the cable connects to the modem and the other end to the cable box. A modem also connects to the router and delivers Internet connectivity to the home or business network.

Do I need a modem if I have a router?

Yes, you will need a modem if you have a router. A modem provides you access to the internet service via your ISP. In other words, you can’t connect to the Internet without it. A router, on the other hand, only allows multiple devices within a network to connect to the Internet.
