Backup Internet, powered by eero Signal

Backup Internet

If your fiber connection is ever interrupted, your Wi-Fi switches to a 4G LTE cellular connection automatically — and switches back when service returns.

Automatic switchover Cellular data included Works with your eero

The simple way to stay connected.

eero Signal is a small cellular companion for your eero. It sits quietly in the background until your main connection drops — then it takes over.

Flexible

Put it where your cell signal is strongest.

eero Signal pairs with any compatible eero in your home, so you can place it wherever cell reception is best.

Easy

Plugs right into your eero.

One included cable connects it to your eero and shares a single outlet. Setup takes a few taps in the eero app.

Automatic

Switches over on its own.

If your fiber connection goes offline, your network moves to cellular without you lifting a finger — and moves back when service returns. The eero app lets you know either way.

Backup Internet, answered

Is eero Signal a router?

No. eero Signal provides a cellular connection to the internet — it doesn't make Wi-Fi of its own. It connects to your eero, and your eero keeps delivering Wi-Fi to every room as usual.

Do I need a separate data plan or subscription?

No. Cellular backup data is included in the monthly cost of the Backup Internet add-on. There's no cell carrier account to set up — the built-in eSIM selects the network automatically.

How does the switchover work?

When your main connection goes fully offline (typically for up to a minute), your eero network switches to cellular automatically and the eero app sends you a notification. When service returns, it switches back on its own. Very brief blips may not trigger a switch.

How fast is the backup connection?

Slower than fiber — it's built to keep you connected, not to match your fiber plan. eero estimates typical 4G LTE backup speeds of 11–48 Mbps download and 3–27 Mbps upload. Actual speeds depend on cell coverage where you live.

Does it work during a power outage?

Not on its own. eero Signal has no built-in battery, so it needs power just like your eero does. Backup Internet covers interruptions to your internet connection, not to your home's electricity — a battery backup (UPS) can keep both running through a power outage.

Can I use it as my main internet connection?

No. eero Signal is for backup only, at a single home, alongside your Wire 3 fiber connection.
