Does Eero Need A Modem? ( Complete Guide 2024 )

Eero is a popular brand of Wi-Fi mesh systems that is designed to provide seamless and reliable internet connectivity throughout your home or office.

One of the most common questions that people have when considering Does Eero Need A Modem?

Yes, Eero requires a modem to connect to your internet service provider’s (ISP) network. It replaces your router not modem.

In this article, we will explore this in detail and provide a comprehensive guide to help you set up your Eero Wi-Fi mesh system.

So, if you’re considering investing in an Eero system or are simply curious about how it works, read on to learn more.


What is Eero?

Eero is a Wi-Fi mesh system that provides seamless internet connectivity throughout your home or office. It uses multiple interconnected nodes as access points to create a network that automatically optimizes performance and resolves issues in real-time.

Eero also offers features such as parental controls, device prioritization, and guest networks, easily managed via the Eero app.

It consists of:

  • The Eero router, which connects modem and internet source
  • Eero satellites, to extend the range of your network

The components collaborate to ensure your entire home has a robust WiFi signal, eliminating dead zones.

Does Eero need a modem? 

Yes, Eero does need a modem to connect to the internet. A modem is a device that connects your home network to the internet through your internet service provider (ISP). It is a necessary component for any internet connection that uses a wired connection, such as cable or DSL.

It gets the internet signal from your provider and sends it to your Eero router, which spreads it to all Eero nodes in your home.

An eero system is designed to work with any modem that is compatible with your ISP’s internet service. The modem connects to the internet through your ISP and then the eero system connects to the modem to distribute the internet signal throughout your home.

Understanding ISP’s

If you’re looking to set up an Eero network in your home, it’s important to understand the different types of internet connections and devices that may be involved. Depending on your internet service provider (ISP) and the type of connection you have, you may need a modem, a router, or both.


If your ISP provides an all-in-one modem/router unit, you can use that device to connect to the internet and create a Wi-Fi network.

Fiber optic or Ethernet

If you have a fiber optic or ethernet connection, you’ll need a separate router like Eero to create your Wi-Fi network. It’s important to note that Eero gateways have routing capabilities but not modem functionality.

Only Modem

If your ISP only provides a modem, you’ll need to add an Eero router to create your Wi-Fi network.


If your ISP provides an all-in-one modem/router unit, you can replace their device entirely with an Eero network. By understanding the different types of internet connections and devices, you can ensure a smooth and successful setup of your Eero network.

How Does a Modem Work?

A modem is a device that connects your computer or other devices to the internet. It stands for “modulator-demodulator” and works by converting digital data from your device into analog signals that can be transmitted over telephone or cable lines.

When you request information from the internet, such as loading a webpage, your computer sends a signal to the modem, which then sends a request to your internet service provider (ISP).

The ISP responds by sending the requested information back to the modem in the form of analog signals, which the modem then converts back into digital data that can be understood by your device.

Modems can come in different types, depending on the type of internet connection you have.

For example, cable modems are used for cable internet connections, while DSL modems are used for DSL connections. 

Does Eero Need a Specific Type of Modem?

Eero is compatible with most modern modems, including cable and DSL modems.

However, Here are the key things to consider when choosing a modem for your Eero system:


Make sure the modem is compatible with your ISP’s technology.


Ensure the modem can handle the speed of your internet plan.

Standalone modem:

Consider getting a standalone modem, but keep in mind that if it has built-in WiFi, you’ll need to put it in bridge mode when using it with Eero.

When I upgrade to Eero, do I need to replace my modem?

To get the best performance from your Eero network, you may need to upgrade your modem.

Eero is designed to work with modern modems that support the latest networking technologies, such as DOCSIS 3.1 for cable modems.

If your modem is more than a few years old, it may not be compatible with Eero and may need to be replaced.

Check the compatibility of your modem with Eero, and upgrade if necessary to enjoy faster internet speeds and better performance from your home WiFi network.

How to Setup Eero with Modem?

If you have a modem/router combo from your internet service provider (ISP) and want to set up an Eero system, you can do so by following these steps:

  • Disconnect your modem/router combo from power and unplug any Ethernet cables.
  • Plug one end of an Ethernet cable into the modem/router combo’s LAN port and the other end into the WAN port on your Eero device.
  • Connect the Eero device to power and wait for it to power on.
  • Open the Eero app on your phone and follow the in-app setup instructions to set up your Eero network.
  • Once your Eero network is set up, you can connect your devices to the Eero network using WiFi.
  • If you want to disable the WiFi on your modem/router combo, you can do so by logging into the device’s settings and disabling the WiFi feature.

Your Eero system should now be set up and running with your modem/router combo.

How to Setup Eero with Standalone Modems?

To set up an Eero system with a standalone modem, simply follow these steps:

  • Connect the modem to the coaxial cable and power it on.
  • Then, connect your Eero gateway to the modem with an Ethernet cable.
  • The eero will automatically obtain a public IP address from the modem and start working.
  • If you need to extend coverage, place Eero satellites throughout your home.

The Eero gateway serves as the router, while the standalone modem handles the cable or fiber connection, making it a simple and easy setup process.

How to Setup Eero with Fiber Optic Internet

Setting up an eero system on fiber internet is a breeze. Here’s how to do it:

  • Connect the fiber optic line to the ONT and power it on.
  • Connect your Eero gateway directly to the Ethernet port on the ONT.
  • The eero will come online and start broadcasting WiFi.
  • Add Eero satellites around your house to improve coverage.
  • Since fiber internet provides a direct Ethernet handoff, there’s no need for a modem.

You can connect your Eero gateway straight to the ONT, resulting in a high-performance mesh network. This setup is simple, clean, and reliable.

Tips for Placing Your Eero Devices for Better Performance

To maximize your Eero mesh network’s WiFi performance, proper placement of your devices is crucial. Here are some tips:

  • Center the gateway eero near the modem/ONT if possible as it provides the best starting point for your network.
  • Place eero satellites in between the gateway and dead zones to relay the signal effectively.
  • Keep Eero’s out in the open and avoid hiding them in cabinets or media consoles.
  • Position units on a flat surface that is halfway between the floor and ceiling
  • Try to minimize obstructions like thick walls, metal objects, and interference from other electronics.
  • Hardwire satellites with Ethernet if possible for the best performance.

Remember that every home’s layout and construction materials are different, so experiment with different setups to achieve strong, whole-home WiFi. With some tweaking, you can optimize your Eero mesh network’s performance.

Eero Advanced Setup Options

While the previous information covers standard setups, eero also supports more advanced configurations, including:

VLAN tagging:
