Now, imagine setting up Eero with AT&T fiber. The two components will blow your mind. The process is simple, provided you follow the instructions for the letter.

Let’s dive into it.

Do AT&T Fiber Modems work with Eero Wi-Fi Units?

Short answer – Yes, it does.

The former can offer amplified capabilities such as constant network speeds and signal strength while connected to an AT&T.

Furthermore, Eero units complement an already existing AT&T modem, thus increasing security, bringing stability, and extending the network range.

An Eero mesh router system has a specific uniqueness that enables it to route any network traffic dynamically.

Afterward, it will trace the best routes that support a reliable network signal and maintains the speed.

Also, note that any device connected to an Eero mesh Wi-Fi network will go through a similar process as described above.

How to Set Up Eero With AT&T Fiber?

We’ll now discuss setting up an Eero Wi-Fi with an AT&T fiber.

Disable your U-verse Wi-Fi (ensure there’s no TV service)

The first step isn’t necessary but still crucial since it’ll help you avoid conflicting Wi-Fi networks.

Therefore, start by turning off your 5GHz and 2.4GHz on the supplied device combination of router and U-verse modem.

Since a U-verse TV feature will only work via a wireless connection from supplied devices, carry out the procedure without a TV.

AT&T U-verse

Remember, when stuck, you can always contact U-verse when you need clarification or the setup seems unclear to you.

After that, you’ll follow the steps below to disable your Wi-Fi:

  • First, ensure you have an open browser window.
  • Then, locate the search bar, type in, and click Enter.
  • Next, log into the AT&T U-verse modem account.
  • Choose ‘Wireless’ indicated in the Home Tab.
  • Switch the options to Disabled from Wireless Interface, then press Save.

Set up an IP passthrough.

Secondly, generate an IP passthrough and set the Eero with the router/modem device. The setup will enable you to use all the advanced features of the Eero as opposed to the bridge mode.

The step here will require you to use a specific guideline. Alternatively, you can contact U-verse customer care.

However, if you wish to do it on your own, you may proceed with the following instructions:

Usually, a configured device gets a LAN IP designation. But, devices in passthrough mode assume the WAN IP state.

Additionally, the devices you’ve connected during the passthrough mode may be unable to share files with devices connecting to the gateway.

Step one: Figure the equipment that AT&T provides, either a 2Wire/Pace device or a Motorola.

Step two: Use an ethernet cable to connect a laptop or PC directly to the available AT&T gateway device.

Put your Euros into bridge mode.

The last and final step is, by far, the easiest solution when connecting the U-verse to your Eero. Normally, U-verse will pass traffic on the network thanks to its nature and mandatory requirements.

As such, if you use an Eero in its bridge mode, you’ll receive similar benefits to an Eero mesh. At the same time, the U-verse will continue to control all routines of your network.

Despite being simple, you might experience some disadvantages with the bridge mode. Often, you’ll lose Eero’s advanced features, including:

  • Apple Homekit
  • ACS (Automatic Channel Selection), which subsequently disables the DFS
  • Advanced network settings management through the Eero app
  • Device blocking
  • Device bandwidth usage details
  • Eero labs
  • Eero secure
  • Family profiles

Either way, if you are setting up the Eero in a bridge mode, use the following outline:

  • Access your Eero application, then locate the Settings option at the bottom right phone/PC corner.
  • Choose ‘Advanced,’ then press DHCP & NAT.
  • Switch from ‘Automatic’ to ‘Bridge’ in the selections area, then save the changes made via that ‘Save’ option.  

Cannot Set Up Eero With AT&T Fiber: How to Fix

When installing your Eero with an AT&T modem, you might encounter some challenges. Luckily, most of the conflicts are solvable via some troubleshooting methods.

Disabling AT&T Wi-Fi

It’s often possible to simultaneously use Wi-Fi broadcast from your Eero device and AT&T gateway device.

The Eero broadcasts Wi-Fi signals, whereas the default gateways have several bandwidths like 2.4GHz and 5GHz.

While it looks appealing, it will be disastrous since your devices must choose between your three available Wi-Fi signals.

Consequently, sending files across devices might culminate in errors. Resolving this problem will need you to disable AT&T from your device.

Power Cycling the Eero Units and AT&T Modem

A power cycle normally solves most network issues. The stepwise guide if you want to power cycle an AT&T modem is below.

  • Disconnect the power supply cord from the modem/Gateway and leave the device for at least 20 seconds.
  • Re-connect the cord and allow some time for the device to initialize.
  • After a few minutes, the broadband light will turn solid green.

Procedure for power cycling an Eero device.

  • Remove the device from its power supply and rest for two to five minutes.
  • Secondly, re-plug the Eero into the main power and give it time to initialize.
  • A flashing LED indicator means your Eero is continuing to initialize. On the other hand, a solid white implies an already initialized Wi-Fi broadcast.

Router Placement

How do you place your router? Usually, the manner and location in which you place it can affect your network’s stability, range, and strength.

We recommend strategically putting the Eero units in a straight line to assist in inter-device communication, especially in thick-walled houses.

Ultimately, signals won’t necessarily have to traverse through walls during transmission.

Contrarily, closed spaces such as a cabinet are detrimental to Eero’s system during signal transmission.

Reaching out to AT&T and Eero support

Contacting customer care support

Lastly, if you’ve tried power cycling the gateway or connecting to your internet through the Wi-Fi network with no luck, consider contacting AT&T services. It could be a result of outages within the area.

After confirming that the problem isn’t with AT&T, examine your Eero and verify its effectiveness. If it has an issue, contact Eero support or remove and re-add the challenging Eero device to the application.


As we conclude, this article was beneficial to you. Setting up your Eero with an AT&T U-verse isn’t tedious, although it could involve contacting more experienced personnel.
