On the list of the most annoying things that can happen in your household, we’d say that an unstable internet connection holds one of the top spots.
While eero is a high-quality, reliable option for whole-home internet coverage and fast internet, you can also experience connection issues with their device.
In case you’re noticing a blinking blue light on your eero device, there are several issues that could be compromising the eero system.
Let’s see how you can easily troubleshoot your eero device, get rid of the annoying blinking blue light, and ensure a stable internet connection.
Why is your eero blinking blue?
Whether you’re using eero Beacon, eero pro, or any other eero router for that matter, you will notice that it comes with different light indicators that can display flashing or steady lights.
Depending on the light colors and patterns, you will be able to distinguish, or at least assume what the problem might be.
As you probably already know, if there is no light activity on the eero router, this simply means that the system is inactive and you need to activate it/turn it on/plug it into the power source.
A blinking white light on your eero system indicates that the system is trying to establish an internet connection and it is basically starting up.
Once the white light becomes solid, this means the internet connection has been established and the system is now functioning properly.
If you notice a green blinking light on your eero device, this usually means that the system has detected multiple eero devices, whereas a yellow blinking light usually means that there is a problem concerning USB-C voltage.
As with many other devices, a solid red light will indicate a bigger issue. In this case, a solid red light on an eero device means that there are connection issues stopping the device from establishing an internet connection.
Now, before we get into the most common issues behind a blinking blue light on your eero unit, it is also important to address the solid blue light.
If there are no blue led flashes, but the blue light activity is solid, this usually means that you’ve successfully connected the device to your eero app and you should follow the configuration steps to set it up.
However, blinking blue light can have several meanings and point to different issues, especially if it is active while you’re experiencing problems with your internet connection.
1. WPS mode
A blinking blue light on your eero unit often means that the device is now entering the WPS (Wi-Fi Protected Setup) mode as it is trying to connect to a wireless device.
This basically means that the eero is establishing a connection with the other device, and it doesn’t point to any underlying issues with your system or internet connection in general.
2. Bluetooth broadcasting
Another possible scenario behind a flashing blue light on your eero modem or router is that you’ve enabled Bluetooth broadcasting and the pairing mode is now turned on.
This means that you can now connect your devices via Bluetooth. However, if the flashing blue light persists even after you’ve connected the device, it could indicate a completely different issue.
3. Mismatched connections
Often, when setting up the eero system, it is possible to mismatch the connections and plug the cables into the wrong ports.
In this case, it is probable that the flashing blue light is indicating a mismatched connection, as it is unable to function properly until you set up the system according to the user manual.
4. Damaged system components
Blue led flashes on your eero unit could also signify a faulty element in your eero system, whether it be a cable, wire, port, modem, or router.
Whether it is a manufacturing defect or a defect that has happened when you were transporting, unpacking, or moving your device, even the slightest defect could compromise the entire eero system.
5. Internet Service Provider issues
If you’ve made sure that there are no issues on your end, but the flashing blue light is still on, it could be indicating a problem with the Internet Service Provider (ISP).
It could be that the provider is changing their network configuration. Another possibility is that there is a service outage in the area or a power outage.
6. Physical blockages
Even if there is nothing wrong with your service provider, and the modem and the router have no physical defects, certain physical blockages could be affecting internet connectivity.
It is possible that you’ve placed the router too close to an object (usually a wall), or that you haven’t positioned it properly on a flat surface.
A buildup of dirt and dust could also do more damage than you could imagine, which is precisely why it is important to keep all the components clean.
How to fix an eero blinking blue?
Even if you were unable to detect the issue yourself, there are still effective methods you can use to improve your internet connection and get rid of the annoying blinking blue led light on your eero unit.
Let’s go over some of the best solutions you can use to tackle the issue with your eero network.
1. Connect the device via WPS mode
As we’ve explained, blinking blue light can often indicate that the eero device has entered WPS mode, which means that you can now connect your wireless device to the internet.
However, you may need to enter a passcode to establish this connection, or simply click “next” on your device to complete the process.
Therefore, if you’re currently trying to connect a wireless device to the eero network, make sure you’ve completed all the necessary steps.
Once the connection has been secured, the flashing blue light should go away. However, if the connection attempt was unsuccessful, you should look into other possible issues.
2. Connect the device via Bluetooth
Another possibility is that the eero unit is informing you that the Bluetooth has been activated, and you can now connect the desired device using Bluetooth pairing.
It is also possible that you need to enter a passcode, or simply go through the steps you see on the screen to establish this connection.
Once again, if the connection attempt was unsuccessful, or the flashing blue light isn’t gone after you’ve successfully paired the devices, this wasn’t the issue in the first place.
3. Check the connections
If you conclude that there is nothing wrong with the software or the network itself, there is always the possibility of a physical error.
In this case, it is probable that you haven’t connected all the components properly during the setup process.
The best way to find out if you’ve made a mistake in setting up the eero system is to take a look at the user manual or contact eero customer service for further guidance if necessary.
Make sure to inspect the entire eero system, focusing on matching all the connections to their specific ports.
4. Check for any damaged or faulty components
Even if you’ve connected everything according to the manual, it is still possible that the components you’re using aren’t functioning properly.
Look for any visible defects, whether it be a defective cable or a loose wire, and make sure to replace them as soon as possible.
As you’re inspecting the eero system, you should also take a look at other elements, such as the power outlet, or the splitter (if you’re using one).
You can troubleshoot these elements by plugging in the device to another power outlet, or removing the splitter and connecting the system directly.
5. Contact your ISP
In case of a service outage or an area power outage, all you can do is wait for the problem to be fixed.
If you’re unsure whether there has been a service outage, you can contact your ISP and get the latest information.
The customer service will also inform you of any network configuration changes, as well as any ongoing processes that could affect your internet connection.
6. Remove any physical blockages
Your eero gateway should be located on a flat surface, and not pushed up against the wall, as this kind of positioning could affect the components, as well as the wireless signal.
It is also recommended to clean the eero device regularly to prevent any particles and dirt from building up inside the unit.
7. Reset your eero device
Another efficient method you can use to eliminate any minor bugs and/or restore factory settings is to reset your eero device.
If you’re using the eero app, you can reset your eero gateway online in a few simple steps.
Launch the app, then navigate to Settings. Once you open the settings, select Advanced options, then click on Reset.
The final step would be to select Reset Network, which won’t erase any changes you have made to eero settings since this is a form of a soft reset.
If you want to reset the device manually, find the eero reset button located on the back or the bottom of the device.
In case you’re using the eero beacon device, you will find the eero nodes on the left side of the unit.
For a soft reset, which will save all your custom settings, hold the reset button for no longer than 7-10 seconds. Once you notice a yellow flashing light, release the reset button and wait for a solid white light to show up.
A hard reset, which is basically a factory reset, will completely remove your eero from the network, and delete all your custom network settings.
What’s more, after performing a factory reset, you will have to set up your device all over again, including all your custom settings and adjustments.
For a hard reset of your eero system, hold the reset button for 20 seconds, or until you see a blinking red light on the device.
If the hard reset was successful, you should now see a blinking blue light which means that the device is ready to be set up.
