Eero mesh Wi-Fi systems are known for providing seamless and reliable internet coverage, but like any networking device, they can sometimes run into issues. One common problem Eero users face is the blinking red light, which indicates a loss of internet connectivity.

If your Eero is blinking red, it means your device isn't able to establish a connection with your ISP (Internet Service Provider). This could be due to internet outages, modem issues, faulty cables, or a problem with your Eero router itself.

The good news is that you can usually resolve this issue with a few troubleshooting steps. This guide will take you through a step-by-step approach to diagnosing and fixing the problem, ensuring your Eero system is back online quickly.

Step 1: Check Your Internet Connection

Before troubleshooting the Eero device, check if your internet is actually down.

How to Check:

  1. Use Another Device: Connect your laptop, phone, or tablet directly to the Wi-Fi network and check if it has internet access.
  2. Try Wired Connection: Plug a computer directly into your modem using an Ethernet cable to see if you get a stable connection.
  3. Visit Your ISP’s Website or Social Media: Some internet providers post updates about service outages.
  4. Reboot Your Modem:
    • Unplug your modem from power.
    • Wait for 30 seconds.
    • Plug it back in and wait for it to reconnect.

If your internet is down, you may need to wait for your ISP to restore service. If your internet is working but your Eero is still blinking red, move on to the next step.

Step 2: Restart Your Eero System

A simple reboot can resolve many connectivity issues.

How to Restart Your Eero Device:

  1. Unplug your Eero device from the power source.
  2. Unplug your modem from power and wait 30 seconds.
  3. Plug your modem back in and wait until the connection is fully established.
  4. Plug your Eero back in and wait for it to restart.
  5. Check the Eero light: If it turns solid white, your connection is restored. If it's still blinking red, proceed to the next step.

Step 3: Check Ethernet Cable and Connections

Sometimes, a loose or damaged Ethernet cable can cause connectivity issues.

How to Check:

  1. Ensure the Ethernet cable is securely connected between your modem and Eero device.
  2. Try a different Ethernet cable to rule out cable damage.
  3. Test another Ethernet port on your modem, if available.
  4. Check for physical damage on cables, ports, or connectors.

If replacing the Ethernet cable doesn’t fix the issue, move on to the next troubleshooting step.

Step 4: Use the Eero App for Diagnostics

The Eero app can help diagnose network issues and provide solutions.

How to Check in the Eero App:

  1. Open the Eero app on your smartphone.
  2. Look for alerts or error messages.
  3. Tap on the "Network" tab to check for status updates.
  4. If an update is available, install it to ensure your firmware is up to date.
  5. Use the “Internet Check” tool to verify if Eero is detecting an internet signal.

If your app confirms a connection problem, you may need to reset your Eero device.

Step 5: Perform a Soft Reset

A soft reset clears network settings but keeps custom configurations.

How to Soft Reset Eero:

  1. Find the reset button on the back of your Eero device.
  2. Press and hold the button for 7 seconds until the light flashes yellow.
  3. Release the button and wait for the Eero to reboot.
  4. Check if the Eero light changes to solid white, indicating a successful connection.

If the problem persists, try a hard reset.

Step 6: Perform a Hard Reset (Factory Reset)

A hard reset erases all network settings, requiring you to set up your Eero from scratch.

How to Hard Reset Your Eero:

  1. Locate the reset button on your Eero.
  2. Press and hold the button for 15+ seconds until the light turns red.
  3. Release the button and wait for the Eero to reboot.
  4. Open the Eero app and follow the setup process again.

Factory resetting should be a last resort, but it can resolve persistent connectivity issues.

Step 7: Update Eero Firmware

Outdated firmware can cause connectivity problems.

How to Update Eero Firmware:

  1. Open the Eero app and navigate to Settings > Software Updates.
  2. If an update is available, install it.
  3. Restart your Eero after updating.

Keeping your firmware up to date ensures your Eero operates smoothly.

Step 8: Contact Eero Support or ISP

If your Eero is still blinking red after troubleshooting, reach out for help.

When to Contact Eero Support:

  • Your Eero device fails to reset.
  • The app does not recognize the Eero device.
  • You suspect a hardware failure.

When to Contact Your ISP:

  • Other devices also can’t connect to the internet.
  • Your modem isn’t receiving a signal.
  • You suspect an outage in your area.

You can contact Eero Support via their website or the Eero app for further assistance.

A blinking red light on your Eero can be frustrating, but following these steps can quickly restore your internet connection:

  1. Check your ISP status and restart your modem.
  2. Power cycle your Eero device.
  3. Ensure Ethernet cables are properly connected.
  4. Use the Eero app to diagnose issues.
  5. Perform a soft reset or hard reset if necessary.
