Every Amazon eero unit uses a single LED on the front to tell you exactly what state the device is in, from a healthy network to a dropped internet connection. The most worrying one for most people is the red light, which simply means the eero has lost its connection to the internet. The colours and flashes are the same whether you run an eero in the UK or the US, because they are set by the device firmware rather than by any individual broadband provider. This guide explains each LED state in plain terms, deals with the red light fault in detail, and walks through the reboot, soft reset and factory reset steps that clear the most common problems. Everything here is based on eero's own support documentation so the meanings and reset timings are correct for current eero, eero Pro and eero Beacon hardware.
A solid white eero light means the network is healthy. Flashing white is the eero booting up, flashing blue means it is ready to set up in the app, and solid blue means the app is connecting. A red light is the important fault: the eero has no internet, usually a modem or ISP issue, so power cycle the modem before resetting the eero itself.
Key Takeaways
- Solid white is the healthy state and means the eero network is up and working normally, unless the LED has been dimmed or switched off in the app.
- A red eero LED means there is no internet connection, which is a WAN fault between the modem and your ISP rather than a fault inside the eero.
- Flashing blue means the eero is ready to be set up in the app, and solid blue means the app has connected and is configuring the network.
- A soft reset reboots the eero and keeps your settings, while a factory reset wipes it and returns the LED to flashing blue ready for fresh setup.
- When the light is red, power cycling the modem or ONT for three minutes fixes far more cases than resetting the eero, so try that first.
Amazon eero light meanings at a glance
| Light | What it means | What to do |
|---|---|---|
| Solid white | Everything is running correctly and the eero network is online. This is the normal healthy state. The white LED can also be dimmed or turned off in the eero app, so a unit with no light is not always a fault. | No action needed. If you prefer the light off at night, schedule or disable the LED under that eero's settings in the app. |
| Flashing white | The eero is booting up or starting its connection after being powered on or rebooted. It is working through start-up checks and is not yet ready. | Wait a few minutes. The LED should settle to solid white on its own. If it stays flashing white for a long time, power cycle the unit by unplugging it for 30 seconds. |
| Flashing blue | The eero is in setup mode and ready to be added in the eero app. It is broadcasting over Bluetooth so a nearby phone can find it during setup, which is also the state a unit reaches after a factory reset. | Open the eero app, keep your phone close to the unit, and follow the in-app prompts to add or set up the eero. |
| Solid blue | The eero app has connected to the unit and is in the middle of setting up or configuring the network. This is a brief step during setup, not a fault. | Stay in the eero app and follow the configuration steps. The LED moves to solid white once setup finishes successfully. |
| Flashing green | More than one eero has been detected during setup. The unit has found other eeros nearby and is sorting out which to add. | Continue setup in the app and add the eeros one at a time as prompted. The light returns to white once the network settles. |
| Flashing yellow | This brief flash appears while you hold the reset button for a soft reset. It confirms the soft reset point has been reached. | Release the reset button as soon as the LED flashes yellow to complete a soft reset that keeps your settings. |
| Solid red | The eero has no internet connection. This is a WAN fault, meaning the link from your modem or ONT to your ISP is down, rather than a fault inside the eero itself. | Power cycle your modem or ONT by unplugging it for three minutes, then wait 5 to 10 minutes for it to reconnect. Check the cable into the gateway eero and confirm there is no ISP outage. |
| No light | The eero is off or has no power. The LED may have been switched off in the app, or the unit is not receiving power from the adapter or socket. | Confirm the LED is enabled in the app, then check the power adapter, cable and wall socket. Try a different outlet or adapter, and power cycle the unit for 30 seconds. |
The red eero light means no internet, not a broken eero
A red LED is the fault people search for most, and the meaning is specific. It tells you the eero has lost its connection to the internet, which eero calls a WAN issue: the link from your modem or fibre ONT out to your internet provider has gone down. The eero hardware itself is usually fine. That distinction matters because resetting the eero will not fix a problem that lives in the modem or with the ISP.
Work through it in order. First, check whether your provider has an outage, because if the line is down nothing you do to the eero will help. Next, make sure the Ethernet cable from your modem or ONT is plugged firmly into the gateway eero, the unit that connects directly to your modem. A loose or damaged cable is a common cause of a red light. If the connection looks fine and there is no known outage, move on to power cycling the modem, which clears the largest share of red-light cases.
Power cycle the modem before you touch the eero
Because a red light is almost always a modem or ISP fault, the modem is where the fix usually lives. Unplug your modem or fibre ONT from power and leave it off for at least three minutes so it fully powers down. While it is off, check that the cable feeding your gateway eero is seated in the correct port, which on a modem is often labelled LAN or Ethernet.
Plug the modem back in and give it time. It can take 5 to 10 minutes to come back online and re-establish the connection to your provider. Once the modem is back, the gateway eero should pick up the connection and the LED should return to solid white. If it is still red after the modem has fully come back, try a different Ethernet cable between the modem and the gateway eero, then repeat the cycle. If it still will not connect, the next call is to your ISP, since some providers need a specific line configuration before a router like eero can get online.
A soft reset reboots the eero without losing your setup
A soft reset is the gentler option and is the right first move for an eero that is sluggish, dropping devices or stuck on a flashing light. It reboots the unit and returns it to its default wifi channel while keeping it on your network and saving advanced settings such as IP reservations and port forwarding.
Find the small reset button, usually on the back or underside of the unit, and hold it in with a pin or paperclip. Keep holding until the LED flashes yellow, which takes around seven seconds, then release. The eero restarts and should come back to solid white. You can also reboot a single eero from the app, or simply unplug it for 30 seconds and plug it back in, which has the same effect as a power cycle.
A factory reset wipes the eero back to flashing blue
A factory reset, also called a hard reset, is the bigger step. It clears all user data and logs and removes the eero from your network, so it returns to the same out-of-the-box state as a brand new unit. Use it when you are selling the eero, starting a network from scratch, or troubleshooting a unit that will not recover any other way.
Hold the reset button until the LED flashes red, which takes around fifteen seconds, then release. After a successful hard reset the LED settles into a flashing blue state, which means the eero is ready to be set up again in the app. From there you add it back through the eero app as if it were new. Because a factory reset erases your configuration, only reach for it after a soft reset and a modem power cycle have failed.
White and blue lights during setup are normal, not faults
Several of the colours only ever appear while you are setting up or rebooting, and they are easy to misread as problems. Flashing white is simply the eero booting up, and it should give way to solid white within a few minutes. Flashing blue means the unit is in setup mode and broadcasting over Bluetooth so your phone can find it in the app. Solid blue is the brief moment when the app has connected and is configuring the network, and flashing green shows that more than one eero has been detected during setup.
None of these need fixing on their own. They are steps along the way to a healthy solid white light. If a unit gets stuck on flashing white or flashing blue and never reaches white, treat it like any other stall: power cycle it, check the cabling to the gateway, and if it still will not progress, run a soft reset.
When the eero light keeps going red, weigh up the hardware
Most red-light events are one-off modem or ISP hiccups that a power cycle clears. If the light goes red repeatedly, and you have already ruled out the modem, the cabling and the ISP, the problem may sit with ageing hardware or a unit that has genuinely failed. An eero that constantly drops its WAN connection despite a healthy modem, or one that will not hold a solid white light after a factory reset, is a candidate for replacement.
Before spending anything, decide whether the issue is the gateway eero or the wider mesh. A single failing satellite can often be removed without replacing the whole set, whereas a failing gateway affects everything. The dead-zone and upgrade guides below help you work out whether you need a new unit at all, or whether a different placement or an extra satellite would do the job for less.
