You look over at your eero and it’s glowing red. No internet. Nothing working.
An eero red light is almost always a connectivity issue, not a hardware failure. And in most cases, you can fix it yourself in a few minutes without touching the eero app or calling support.
Here’s exactly what to do.
What Does the Red Light on Your eero Mean?
A solid red light means your eero has lost its WAN connection. That’s the connection between your eero and the internet coming from your ISP. Your eero is on, it’s powered up, but it can’t reach the outside world.
A blinking red light is different. That only appears when your eero is in the middle of a factory reset. If you didn’t initiate one, and the light is blinking red, just wait. It’ll either complete the reset or stabilize on its own.
One more distinction worth knowing: where the red light appears matters.
If it’s your gateway eero (the one plugged into your modem), the problem is between your modem and the internet. If it’s a satellite node showing red, that’s usually a placement issue, not an ISP problem. More on that below.
If your eero is showing no light at all rather than a red one, that’s a completely different issue with its own set of fixes.
Check Your ISP Before You Do Anything Else
Before you touch a single cable, check if your ISP is having an outage.
If the problem is on your provider’s end, nothing you do to your eero will fix it. You’re troubleshooting the wrong thing.
Go to your ISP’s website on your phone (using mobile data, not WiFi) and look for a service status page or outage map. You can also search “[your ISP] outage” on Twitter or Downdetector for real-time reports.
According to eero’s own support documentation, if your network is offline due to an ISP outage, your best option is to use mobile hotspot backup until service is restored. No reset will fix an upstream outage.
If your ISP looks fine, move on.
Power Cycle Your Modem and eero the Right Way
This fixes the eero red light in the majority of cases. But most people do it wrong.
The correct sequence: unplug your modem (or fiber ONT) from power.
Wait a full 3 minutes, not 30 seconds.
Then plug the modem back in and wait for it to fully come online. Once the modem lights settle, restart your gateway eero by unplugging it for 30 seconds and plugging it back in.
eero’s official troubleshooting guide specifically recommends the 3-minute wait. That’s long enough for your modem to fully flush its connection state and re-sync with your ISP’s network. Rushing it is why power cycles often “don’t work” the first time.
After the eero restarts, give it about 2 minutes to fully boot.
You’re looking for it to settle on a solid white light, which means it’s connected and healthy.
If the red light comes back, keep going.
Red Light on a Satellite Node? That’s a Different Problem
If it’s not your gateway eero showing red but one of your satellite nodes, the cause is almost always placement.
Satellite nodes need to stay within a reasonable range of your gateway eero (or another node acting as a bridge). Too much distance, too many walls, or too much interference between nodes, and the satellite can’t hold its connection. It goes red.
Homeowner.com’s eero guide confirms this: a solid red light on a satellite unit typically means a placement problem, not an internet problem.
The fix: unplug the satellite, move it closer to the gateway, and plug it back in. A good rule of thumb is keeping nodes within 30-40 feet of each other with no more than one or two walls between them. Once the node re-connects, you can try nudging it slightly further out if needed.
Check Your Ethernet Cables
If the power cycle didn’t fix it and it’s your gateway eero showing red, check the physical cable connecting your modem to your eero.
A loose WAN cable is a surprisingly common culprit. Pull the ethernet cable out of both ends and firmly re-seat it. You should hear a click. If the cable looks bent, kinked, or damaged at the ends, swap it for a new one.
Also check the port. Your eero gateway has two ethernet ports. Make sure the cable from your modem is plugged into the correct WAN port (usually labeled, or it’s the one without the LAN label). Plugging into the wrong port means no internet, regardless of how good your connection is.

How to Soft Reset and Factory Reset Your eero
If cables are fine and the red light is still there, it’s time to try a reset.
There are two types. They’re not the same, and the order matters.
Soft reset first. Find the small reset button on the back of your eero (you’ll need a pin or paperclip). Hold it down until the LED flashes yellow, which takes about 7 seconds. Release the button. According to eero’s reset guide, a soft reset reboots the device and resets its WiFi channel but keeps your network settings, IP reservations, and advanced configurations intact. It’s low risk.
Wait for the eero to reboot and check the light. If it goes white, you’re done.
Factory reset as a last resort. Hold the reset button for 15 seconds this time, until the LED flashes red, then release. The light will transition to blinking blue, which means the eero has been wiped and is ready for a fresh setup. You’ll need to set up your network again from scratch in the eero app.
You can also factory reset through the app: go to Menu, then Network Settings, then Advanced Settings, and select “Delete Your Network.” Same result.
Conclusion
The eero red light is almost always fixable without any special tools or technical knowledge.
Work through it in order: check your ISP first, power cycle your modem for a full 3 minutes, verify your ethernet cables, then try a soft reset.
Factory reset is there if nothing else works, but most people never need it.
If the red light keeps coming back after all of that, it’s a sign of a deeper issue, whether it’s an unstable ISP signal, an aging modem, or a hardware problem with the eero itself. At that point, contact eero support directly.
And if your network has been dropping in and out even when the light isn’t red, that’s worth investigating separately.
The fixes for an eero that keeps disconnecting are different from a one-time red light situation. If you’re also thinking about whether to upgrade your plan for better network management tools, eero Plus might be worth a look.
Frequently Asked Questions
Why is my eero showing a solid red light but my phone has internet?
If your phone is on mobile data (not WiFi), it’s using a completely separate connection. The eero red light means the eero itself can’t reach the internet through your modem. The two are independent. Check your modem and ISP connection — the issue is between your modem and your ISP, not with your phone.
How long should I wait when power cycling my eero and modem?
Unplug your modem for at least 3 minutes. This gives it enough time to fully flush its connection state and re-sync with your ISP’s network. According to eero’s troubleshooting guide, you should also wait 5-10 minutes after plugging it back in before expecting a stable connection.
What’s the difference between a soft reset and a factory reset on eero?
A soft reset reboots your eero and resets its WiFi channel but keeps all your settings. You hold the reset button for 7 seconds until the LED flashes yellow. A factory reset wipes everything and returns the eero to out-of-box state. You hold for 15 seconds until the LED flashes red. Always try the soft reset first.
Will a factory reset delete all my eero settings?
Yes. A factory reset wipes your network name, password, device settings, IP reservations, and port forwarding rules. You’ll need to set up your eero network from scratch using the eero app. Only do a factory reset if everything else has failed.
My eero was working fine, then suddenly went red. What happened?
Sudden red lights are usually caused by one of three things: a brief ISP outage that your eero never recovered from, a modem that lost sync and needs a restart, or a loose ethernet cable that got bumped. Start with a power cycle of both your modem and eero. That resolves the majority of sudden red light cases.
