How to Add an eero Node to Your Mesh

Why Add an eero Node

If a room in your home has poor Wi-Fi, adding another eero node can extend coverage to that area. A mesh Wi-Fi system uses multiple mesh nodes that work together, so your devices roam from one node to another instead of staying stuck on a weak signal. This is useful for homes with thick walls, long layouts, or a router placed at one end of the house.

Before adding a node, confirm that your current system actually supports it. Most eero systems are designed to accept extra units through the eero app, but older hardware may need a firmware update first. If you are starting from scratch, a mesh system may be a better fit than adding nodes to an old router. The IEEE 802.11 standard defines the wireless LAN MAC and PHY specifications that Wi-Fi equipment follows, and adding a node simply extends that wireless network across more of your home.

• Video calls drop in one room
• Streaming pauses when you move to another floor
• The farthest room shows a weak signal
• You added a new workspace or entertainment area

Before You Pair the Node

Open the eero app on your phone and make sure it is updated. The app is the main way to add, remove, and manage eero nodes. Keep your phone near the gateway when you begin, because the app needs to discover the new node on the local network.

Plug the new node into power and wait for it to start. Do not place it in its final spot yet. Initial pairing is easier when the node is close to the gateway, usually in the same room. You can move the node after the app confirms the connection.

• Install the latest eero app update
• Plug the new node into a wall outlet
• Keep the node near the gateway for first setup
• Have your Wi-Fi name and password ready

Pair the Node in the App

In the eero app, look for the add or plus button, then choose the option to add a node. The app will scan for nearby eero units and guide you through the rest. If the node has been used before, you may need to reset it so the app can recognize it as new.

Follow the on-screen steps until the app reports that the node is online. The process can take a little time, so do not rush it. If the app asks you to update firmware, allow the update to finish before moving the node.

• Open the eero app from your phone
• Tap Add or the plus icon
• Select Add eero or Add node
• Wait for the app to confirm the connection

Choose the Best Spot for the Node

After the node pairs, unplug it and move it to the area where you need better coverage. A good starting point is halfway between the gateway and the weak spot. The node must still be close enough to hear the gateway through walls and floors. Because mesh relies on wireless links, placing the node too far away can hurt the whole network.

Follow the same router placement advice you would use for a main router: keep the node out of cabinets, away from metal objects, and off the floor. For more ideas, see mesh satellite placement.

• Use an open shelf or tabletop
• Keep the node away from walls
• Avoid putting it behind a TV or in a closet
• Keep it away from large appliances

Check the Connection After Pairing

Once the node is in place, give the mesh time to settle. Walk to the room that had poor coverage and check the signal with a phone or laptop. If the signal did not improve, move the node closer to the gateway or to a more open spot. A gradual adjustment is better than placing the node at random.

Your devices should switch between nodes as you move through the home. This works best when all nodes broadcast the same network name, which is how most mesh systems are configured. For details on how devices choose a node, see Wi-Fi roaming.

Use Wired Backhaul if You Can

If the node has an Ethernet port and you can connect it to the gateway with a network cable, wired backhaul can make the connection more reliable. The cable allows the node to send traffic to the gateway without using a separate wireless hop. That can be especially helpful in larger homes or when walls block the signal.

To set this up, run the cable from the gateway to the node's Ethernet port, then power on the node. The eero app will usually recognize the wired connection and may show a stronger link. Read more about ethernet backhaul and how to set up ethernet backhaul for mesh.

Keep the Network Secure

Adding a node does not change your network's security settings, but it is a good time to review them. Wi-Fi Alliance says WPA3 is mandatory for Wi-Fi CERTIFIED devices and offers more robust authentication. If your eero system supports WPA3, leave it enabled. For a broader refresher, see WPA3 and router security basics.

The Wi-Fi Alliance also explains that WPA3 disallows outdated legacy protocols and requires Protected Management Frames. This is one reason to keep your eero firmware and app current. When a new node joins the network, check for any security notifications in the app. NIST provides cybersecurity guidance for small businesses and the public that reinforces the same habits: use strong passwords, keep software current, and review connected devices.

Troubleshooting a Node That Will Not Pair

If the app cannot find the new node, move it closer to the gateway and try again. Power-cycle the node by unplugging it and plugging it back in. Restart the gateway and give the entire mesh a few minutes to reconnect. If those steps fail, reset the node and repeat the pairing process.

You can find additional advice in troubleshooting Wi-Fi dropouts. The most common cause of a failed pairing is simply placing the node too far from the gateway, so start near the gateway and only move the node after the app confirms that it is online.

Questions

How many eero nodes can I add to one mesh?

The eero app limits the number of nodes depending on your system and model. Start with one new node, add it, and check whether the weak area improves before adding another. There is no single number that applies to every setup.

Can I add an eero node I bought separately?

Yes. The eero app is designed to pair additional eero units to your existing network. The exact steps may differ by model and app version, so follow the on-screen instructions after tapping add.

Do I have to place the new node near the router first?

For initial pairing, keep the node close to the gateway so the app can find it. After it pairs, move it to its intended location and let it reconnect.

Will adding a node make my Wi-Fi faster?

Adding a node can improve coverage and reduce dead zones, but it does not increase your internet plan speed. In some cases, a node too far from the gateway can create a slower connection.

Is it safe to add an older eero model?

Older models may not support the latest security features. Check the app for firmware updates after pairing, and keep security enabled. Wi-Fi Alliance notes that WPA3 provides more robust authentication for certified devices.

What if my new node will not pair?

Move it closer to the gateway, unplug it, restart the gateway, and try again. If the app still cannot find the node, try a factory reset on the unit and repeat the pairing steps.
