How to Reset an eero Router the Right Way

If you only need a quick refresh, restart the eero first. If you need to wipe one unit, use that device’s reset button only. If you want to start over, use the network reset or factory reset path in the app only when you’re ready to rebuild the setup and likely re-enter your Wi‑Fi details.

Which reset do you actually need?

Use the lightest option that fits the problem.

A restart is the first thing I’d try for slow speeds, short dropouts, or a unit that feels stuck. eero recommends simpler steps first. That includes unplugging the unit, waiting 30 seconds, and plugging it back in before you move on to a reset.

A network reset is the middle ground. The exact menu label and behavior can vary by app version, so check the current wording in your app before you tap anything. If the app offers a network-level reset, treat it as the step meant for rebuilding the system, not for a quick refresh.

A full factory reset is the most destructive option. It clears the saved configuration, so it’s the right choice when you’re changing ownership, removing a unit from service, or truly starting over. If you only want the internet to come back after a hiccup, don’t jump to this step.

Use this rule of thumb: restart for a refresh, factory reset one eero to clear one box, and use the broader reset path when you want to rebuild the mesh and set it up again.

What to check before you reset

Before you reset anything, make sure you can get back into the eero app. If the current owner’s account isn’t available, sort that out first, because ownership controls what you can re-add and manage.

Have your Wi‑Fi name and password handy if you expect to set the network up again. It also helps to know which eero is the main unit and which ones are the satellite units, so you don’t reset the wrong device first.

Write down or save any settings you care about before you clear anything. The ones people most often forget are reserved addresses, port forwarding, and custom names.

If the goal is just to see whether the system snaps back to normal, a restart is usually the safer first move. eero also says the device should be powered on for at least 90 seconds and have an internet connection before you reset or reboot it. That keeps you from blaming the eero for a boot that simply hadn’t finished yet.

How to restart an eero for a quick refresh

For a normal refresh, power cycle the unit instead of factory resetting it. This does not erase your network setup.

1. Unplug the eero from power.
2. Wait 30 seconds.
3. Plug it back in.
4. Wait for it to boot fully before you do anything else.

A support guide says this is the simplest and most common restart method. It works for all eero devices, whether it’s your main router or an additional unit. Another source says to allow about 5 minutes for a full reboot to settle, so don’t judge it too quickly.

In practice, the light should come back and settle into a normal online state. One support source says to expect solid white again in about 2 to 3 minutes. Another eero support note says the LED will flash white on initial boot while it establishes cloud communication. That can take up to two minutes, and then it returns to solid white when connection is regained. If it’s still changing states inside that window, give it more time.

If you’re just trying to fix a brief slowdown or a dropped connection, this is the safest first move. It refreshes the device without wiping settings you may want to keep.

How to factory reset a single eero device

A single-device factory reset is the physical-button method. Use it when you want to clear one eero’s configuration, not the whole network.

1. Leave the eero powered on.
2. Find the small reset button on the unit.
3. Press and hold the reset button firmly.
4. Keep holding until the LED shows the reset state.
5. Release the button after the device starts clearing its settings.

For a soft reset, eero says to hold the reset button until the LED flashes yellow. That should take no longer than 8 seconds, then release it. That same official page says the LED will flash white on initial boot and then return to solid white when connection is regained. If your goal is a full factory reset rather than a soft reset, follow the current official instructions for your exact model, because the exact light pattern can vary by device and software version.

If the unit is still powered and the light changes as expected, that usually means you’re on the right track. If nothing changes at all, you may be pressing the wrong control or the reset didn’t hold long enough.

How to reset through the app if that option appears

If the current eero app offers a reboot or reset option, you can use that instead of the button. eero says you can reboot or reset through the app, but the menu labels can change, so go by the wording you see right now.

Open the eero app and go to the current network or device settings. Look for a restart, reboot, or reset action. If you only need a refresh, pick the restart or reboot option. If you’re trying to clear the device or the whole network, read the confirmation prompt carefully before you continue.

This is where people most often go one step too far. A harmless reboot and a destructive reset can look similar on-screen, so don’t tap through on muscle memory. If the app asks for confirmation, that’s your chance to stop and choose the less destructive option.

If the app layout doesn’t match what you expected, trust the labels in the current version and the official eero instructions for that version. Screens change, and an old screenshot is worse than no screenshot at all.

How to tell it worked

A successful restart usually ends with the eero coming back online in the app and the light returning to a normal state. eero says the LED will flash white while the unit establishes cloud communication, then return to solid white when connection is regained.

Give it enough time before you call it a failure. One source says the initial boot can take up to two minutes. Another says to allow about 5 minutes for a reboot to fully settle. A third says 2 to 3 minutes is enough for the light to turn solid white after a restart. If the light is still changing during that time, it may still be working.

For a factory reset, the app may show the device as removed, offline, or ready to be added again. That’s a good sign if your goal was to clear the device, but it can be alarming if you expected the old setup to stay intact.

If the light is steady and the app matches the reset you intended, assume the reset completed. If the unit still looks half-finished after several minutes, move on to the next section instead of pressing the button again.

What to do after the reset

After a restart, check the app and confirm the eero is online. In most cases, your devices should reconnect on their own once the network settles.

After a factory reset, expect to set eero up again. That can mean signing into the app, claiming the device, naming the network, and re-adding extra eeros so the mesh comes back in the right order. If you changed ownership, use the account that should control the system now.

If the eero looks normal but the internet still doesn’t come back, restart the modem too. The issue may be upstream with the modem or your ISP rather than the eero itself.

Put back only the settings you actually need. Recreate custom names, reservations, or forwarding rules after the network is stable, not before.

If it still won’t come back

The most common problem is timing. People think the reset failed because they unplugged the unit too early or checked the app before the boot finished. Give it the full wait window before you try again.

Another common mistake is using the wrong reset type. A restart refreshes the device, but it does not erase settings. A factory reset clears the configuration, but only if you held the correct button long enough and used the correct unit.

Account issues can also look like a reset failure. If the eero was moved to a different owner or the app is signed into the wrong account, the device may seem missing even when it reset correctly. Check ownership before you repeat the process.

If the eero looks fine but the internet still does not return, look at the modem and upstream service next. At that point, the eero may already have done its part.
