Does Eero Need a Modem? A Complete Guide

If you’re wondering Does Eero Need a Modem, the quick answer is Yes. To get your Eero mesh WiFi system working, you’ll need a modem (ISP supplied or your own) to connect to the internet.

This guide will break down how Eero pairs with different types of ISP connections and its setup. Plus, we’ll show you how it can boost your internet speed and reach across your home. Let’s dive into making your WiFi woes a thing of the past.

Quick Answer

Do You Need a Separate Modem with Eero?Yes, Eero devices do not replace your modem; they replace your router.  To use Eero, you still need a modem to connect to the internet.

What is eero?

Eero is a popular mesh WiFi system that provides whole-home coverage. It consists of:

  • The eero gateway router, which connects directly to your modem and internet source
  • eero satellites, which plug into power outlets around your house to extend the range of your network

The components work together to blanket your home with a strong WiFi signal without any dead zones.

Does Eero Need a Modem? – Understanding Eero and ISP Modems

Let’s check out some of the options:

  • Modem/Router Combos – Many ISPs like Comcast Xfinity lease all-in-one modem/router units to customers. In this case, you DO NOT need a separate modem, as the combo device acts as both.
  • Standalone Modems – Some ISPs like Verizon FIOS provide just a plain modem without built-in routing capabilities. Here, you DO need a separate router like Eero.
  • Fiber Optic or Ethernet – If you have fiber internet or a direct ethernet handoff, you may not need a modem at all. Eero can connect directly to the incoming line.

The key is that eero gateways have routing capabilities but NOT modem functionality. So if your ISP only provides a modem, you’ll need to add Eero. If they provide an all-in-one modem/router, you can replace their unit entirely with Eero.

Eero Setup with Combo Modem/Routers

If your ISP provided an all-in-one modem/router combo unit, setting up eero is straightforward:

  1. Connect the combo unit to the incoming cable/fiber line and power it on as normal.
  2. Put the combo device into bridge mode by accessing its settings menu and disabling routing/DHCP. This turns it into a plain modem.
  3. Connect your Eero gateway to the combo unit with an ethernet cable. The eero will grab a public IP address and begin broadcasting WiFi.
  4. Place Eero satellites around your home, connecting them to the app to extend coverage.

With the combo device bridged, the Eero gateway becomes the main router for your network. This provides you with far more configuration options, better WiFi performance, and advanced security features.

Here are some modem-router combo devices you can use with Eero if you don’t have your own modem from your internet service provider or if you want to upgrade and avoid rental fees.

Eero Setup with Standalone Modems

If your ISP provided just a plain cable modem without built-in WiFi, the setup involves:

  1. Connecting the modem to the coaxial cable and powering it on.
  2. Connect your Eero gateway to the modem with an ethernet cable.
  3. The eero will automatically grab a public IP address from the modem and start working.
  4. Place satellites to extend coverage.

It’s that simple! The Eero gateway serves as the router, while the standalone modem handles the cable/fiber connection.

Eero with Fiber Optic Internet

Fiber internet often does not require a modem at all. Instead, you get a fiber optic terminal (ONT) installed inside your home.To set up eero on fiber:

  1. Connect the fiber optic line to the ONT and power it on.
  2. Connect your Eero gateway directly to the ethernet port on the ONT.
  3. The eero will come online and begin broadcasting WiFi.
  4. Add satellites around your house to improve coverage.

Since fiber provides a direct ethernet handoff, eero can connect straight to the ONT without a modem in between. This results in a clean, high-performance mesh network.

Tips for Placing Your Eero Mesh Wifi System Devices

Tips for Placing Your Eero Devices

Once you have your eero gateway connected to the modem or ONT, proper placement is key to maximizing WiFi performance:

  • Centrally locate the gateway eero near the modem/ONT if possible. This provides the best starting point for your network.
  • Place satellites in between the gateway and dead zones to relay the signal effectively.
  • Keep Eeros out in the open, not hidden in cabinets or media consoles.
  • Position units on a flat surface, 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 best performance.

Experiment with different setups – every home’s layout and construction materials are different. With some tweaking, you can achieve strong whole-home WiFi.

Advanced Eero Setup Options

While the above covers standard setups, eero also supports more advanced configurations:

  • VLAN tagging – Useful for commercial networks, VLANs keep devices segmented on separate virtual networks.
  • PPPoE – Some ISPs, like AT&T Fiber, require PPPoE authentication. Eero gateways can be configured with PPPoE credentials.
  • IP passthrough – Allows Eero to grab the public IP address directly from the modem. Useful for gaming and home servers.
  • Cascading eeros – Multiple gateways can be daisy-chained to serve very large spaces like offices, hotels, etc.
  • Static routing – For complex networks with multiple subnets, static routes can be defined.

Eero also provides an app and web interface for deep network customization if needed. Options like Family Profiles, ad blocking, and SQM allow you to tune the network to your needs.
