What is the problem?

The internet is the backbone of our modern society. It helps people connect with each other, do their jobs, and stay informed about what’s happening in the world. 

But when your connection goes down for any reason (like a power outage or an errant cat), it can be frustrating to say the least.

Many people deal with the common problem of no internet with an eero system, and the main symptom is a blue light. There are many different indicators that will tell you what is wrong.

If your connection goes down, the good news is that there are a number of things you can do to stop your internet from going offline. And if it does go out, you’ll know how to fix it quickly so you don’t miss anything important while waiting for broadband service providers to come help.

What does blue light on eero mean?

After a factory reset, the eero will go through a series of lights. The first set of lights are blue to show it is ready for setup. After setup, the light will turn solid blue (or white if you are set up with the eero Plus plan) to indicate it is on and fully operational. If your eero’s light is not blue, it may be because of another issue, which we will cover.

Your eero has not successfully completed the startup sequence yet. Please wait for about 10 minutes for this light to go solid blue.

Your eero is not connected to the internet, or it has lost its connection. If you are running an ISP’s network, please contact your provider for help with getting online. If your eero was working previously but you have reset it, check if your other devices are online or check if there is a problem with your internet instead.

What color should the light on my eero be?

If the LED is white then your eero is functioning correctly. You can confirm this by looking at your app and checking that the eeros is displaying a green icon. If you see both of these then your internet is working and everything is connected as it should be.

In the event that you see yellow outlined lights on both devices, but one has a red or orange outline instead of blue, it may be that either no internet connection was available or something went wrong during setup – in which case, it is recommended to reboot your router/modem before proceeding.

What does a blinking blue light mean on my router?

When your Xfinity router blinks blue, it indicates that it’s in WPS (Wi-Fi Protected Setup) mode and is attempting to connect with another wireless device. 

After you click “next” or enter a passcode, the setting will become solidified and the connection will be established.

Why does eero go offline?

Networks and all of their eeros can be “Offline,” which implies the gateway eero attached to the modem can’t connect. Make sure your eero is properly hooked up to the modem and turned on in this situation. You will need to check your main router if your eero is indeed “Online” but is still experiencing problems connecting.

Why Is My Eero Blinking Blue Light?

Eero’s blinking blue light is caused by Bluetooth broadcasting at the moment, according to official explanations. Eero nodes should display this light when they have entered pairing mode. 

This means that it is not really a serious issue unless you notice that it does this continuously and you are not trying to pair any devices. If that is the case then you can follow our fixing guide below!

How To Fix Eero Blinking Blue Light?

The good news is that there are a few things you can do to fix this easily.  As with all troubleshooting, make sure you are comfortable with following these steps. If you think that you don’t understand any of the steps then be sure to contact eero’s technical support and they will guide you through the process. 

Here is a list of quick and easy things that you can try to fix your eero blinking blue light. For a full version of the below steps be sure to check out the eero guide here.

Inspect your Ethernet Cables

Even if you know for a fact that nothing has interfered with your cabling setup it is not a bad idea to try the following. Unplug and plug in all of the network cables that are plugged into your eero and other devices such as your fibre router or network hub or switch. 

Sometimes a bad connection on a single pin on an Ethernet cable can be enough to cause a bad connection with the rest of your network, making your eero second guess the stability of its connection. Simply press in the retaining clip of your eero Ethernet cable, pull it out until the Ethernet connection light goes out, then plug it back in and press until you feel the retaining clip click back into place. 

If it doesn’t click in, or if the retaining clip is broken off, then you should replace your Ethernet cable and see if that improves things..

Is Your Internet Service Provider Having Issues Upstream?

If you have ever spent  extended periods of time troubleshooting a bad internet connection, only to find that there was a service interruption while you were trying to fix things, then we share your pain! It is always a good idea to call your ISP and ask them if they are experiencing any issues in your area. If they are, then you can find out when they expect the service to resume normally.

Unplug your eero’s power and plug it back in

This is perhaps one of the oldest (and most effective) tricks in the book. If your eeo is having issues with its networking services and you cannot figure out what’s going on, then a simple power cycle is all that is needed. This allows your eero to flush out all the necessary caches and restart the services that it uses to supply you with wireless and internet coverage.

Unplug the power cable from the back of your eero, wait for a few seconds until all the lights are off, then plug it back in. 

Use the App

A network reset is sometimes exactly what the doctor ordered, and to do this you will need to use the eero app on your smartphone. If you don’t already have it set up then now is a good time to install it, provided you have an internet connection (if you are reading this then we hope you are online!)

Steps to reset your eero:

  • Open up the eero app on your smart device
  • Open the settings option
  • Find and open Advanced settings
  • Select Reset
  • Select Restart Network
  • Confirm

You will lose connection during this process, but it will come back online after a minute or two.

Perform A Soft Reset

In this case, the network configurations are cleared, but your custom settings are saved, and Eero stays on the network.

Hold in the reset button for 10 seconds and then let it go when you see a flashing yellow light. Once it has completed its reset you will notice a solid White Light.

Perform a Factory Reset

Hold the reset button for 15 seconds until the LED flashes red, then release it. The eero LED light will flash blue after a successful hard reset, indicating that it is ready to be set up again.

What do the eero light colors on my eero mean?

Each different color means something different. I will explain all of them below:

  • The Light is off – eero isn’t plugged in, or there is no electricity
  • White light that is blinking – eero is starting up its software/internet connection in progress
  • Blue light is blinking –  Bluetooth signal is being broadcasted
  • Blue solid light – The eero app has established a connection and ready to be configured
  • Green light blinking – There is more than one eeros device detected
  • Yellow blinking light – USB-C voltage is incorrect
  • White solid light – eero is on the internet
  • Red solid light – eero can’t connect to the internet

How do I reset my eero?

In the same way as any router, resetting your eero is an effective troubleshooting step. For those who don’t have experience with resetting their eero, we recommend following simple steps, such as unplugging it, waiting 30 seconds, and plugging it back in before performing a reset.

Users of the first-generation eero (and those who currently own a second-generation eero) can reset it by pressing the reset button on the bottom (eero) or hitting the small reset button on the back of the device. 

On the left side of the beacon, you’ll find a reset button. Follow the instructions below. Make sure your eero has been powered on for 45 seconds before resetting it.

Fixing Connection Problems on eero 6 or eero Pro 6

Some older drivers and software may prevent eero 6 and Pro 6 from joining networks. Below are some examples of networks that will not be able to connect:

Connection problems with 802.11ac wireless adapters with Intel® Wireless Adapters for Wi-Fi 6 (802.11ax) routers and access points

A device meeting this criterion might be able to detect and join wireless 6 networks, but it would not be able to detect your network. It is suggested that you update your device’s driver as soon as possible in order to address this issue. 

The issue can temporarily be dealt with by switching to Eero’s Legacy mode. Simply open the Eero app, select Legacy Mode, and follow the instructions.

  • Select the Settings button in the bottom right corner of the eero app
  • Select the troubleshooting option
  • Select the My device won’t connect option
  • Select the My device can’t detect Wi-Fi 6 option
  • Toggle Legacy Mode on

Hopefully now your device can detect and join the Eero network

Wrapping up

The lights on your Eero tell you what the problem might be and how to fix it. If you see a flashing blue light, this means that there is no internet connection or something went wrong during setup – in which case, reboot your router/modem before proceeding. 

A solid white light means that they’re connected to the internet. The blinking green light indicates multiple eeros detected while blinks yellow shows an unapproved USB-C power source has been used with their device (make sure not to use any other chargers). 

Solid red signifies an issue where one of their devices cannot connect to the internet, make sure all cables are plugged in securely and try rebooting both routers if needed!


What does blue light on eero mean?

Upon completing a hard reset, the LED light on the eero will flash blue, indicating that it is ready for set-up again.

What color should the eero light be?

When the LED is white, that means the eeros are working, while the app displays green to confirm they're good to go. In the eero app, if the eeros are yellow but the eero LED is white, it means the device is configuring or setting up.

How long does it take eero to reboot?

As soon as you connect it back to power, your eero will start again. It should take a couple of minutes.

How do I know if my eero is working?

Run the Eero app. From the top of the screen, tap Online. An indicator will appear to the right of each eero's name to indicate their signal strength. When you are connected, you will see the <-> icon.

What do colors mean on eero?

Connecting to the eero app and configuring the network is solid blue. Eero detected multiple times is blinking green. If it blinks yellow, it means the power source is unauthorized.
