Mesh WiFi is fast becoming one of the most popular home network solutions, especially in large homes and expansive properties. What is Mesh WiFi and how it works with your modem or ISP isn’t always fully understood, so here we explore the role of modems and routers in mesh networks, and how to make the right WiFi upgrade for your home.

Understanding the Role of a Modem in a Mesh WiFi Network

The word modem comes from a blend of “modulator” and “demodulator”—a nod to its original purpose: converting digital data to analog signals and back again. While early modems crawled along old-school voice phone lines, today’s models ride the much faster waves of cable TV and digital networks.

The role of a modem in a home WiFi network is to:

  • Receive modulated (coded) signals from an ISP and demodulate (Decode) them to recover the digital signal.
  • Convert digital data signals into modulated analog signals to send back to your ISP.
  • Serve as a link between routers, digital devices, and communication pathways.
  • Enable communication between various devices and connect gadgets such as laptops, Android smartphones, and Apple iPads to the internet.
  • Modems must be connected to and activated with a cable ISP in order to access the Internet.
  • Examples of Cable Internet providers include: Comcast / Xfinity, Charter Spectrum, Cox Communication and others.

The Difference Between a Modem and a Router

You’ve probably heard the terms “modem” and “router” used in tech talk, but you may not understand what they are. Think of a modem like an on-ramp to the internet superhighway—it connects your home to your Internet Service Provider (ISP), giving you access to the wider web. Your router, on the other hand, is like the network of streets inside your neighborhood—it manages traffic between all your devices (phones, TVs, laptops, etc.) and makes sure each one can reach the internet without crashing into the others.

The router creates the WiFi device network, while the modem connects that WiFi network to the internet. When connecting to WiFi, you connect to your router, which forwards traffic between the internet and your computer. Many internet providers offer combined modem/router units.

TIP: Typically – ISPs customer rent a Modem GATEWAY device. Cable Gateways are combination devices that act as both a modem and a WiFi router. If you don’t plan to replace this device, it is recommended to disable it’s WiFi & Routing capabilities if connecting to a Mesh WiFi system. Learn more in our Connecting a Modem and Router blog.

How Mesh WiFi Works with a Modem

A mesh WiFi system consists of the main mesh Router WiFi and multiple Mesh WiFi satellites. Mesh WiFi systems such as NETGEAR Orbi connect to a modem for fast and seamless WiFi coverage for the whole home. It’s worth noting that WiFi modems provided by internet service providers (ISPs) aren’t necessarily the latest WiFi standard.

An underpowered or outdated modem, or a slow ISP plan might not keep up with the latest WiFi 7 router speeds, so it could be time to upgrade your modem and then connecting it with a Mesh WiFi system. And – if you stop renting a gateway your investment in purchasing a separate modem and WiFi router will be recouped over time, as you will no longer be paying monthly ISP equipment rental fees.
