What Does Eero Blinking Yellow Mean?
When you see your Eero device blinking yellow, it’s not just a random signal. Eero uses colored lights to tell you what’s happening with your network. Each color indicates a different status or issue. Here’s a quick summary:
- Solid white: Everything is working as it should.
- Blinking white: The device is starting up or updating.
- Solid blue: The device is in setup mode.
- Blinking blue: The device is ready to connect to the app.
- Solid red: No internet connection.
- Blinking yellow: Problem with the Ethernet cable or port.
So, when you see a blinking yellow light, it usually means an Ethernet cable is not connected properly or there’s an issue with the Ethernet port. This commonly happens during setup or when moving devices.
Main Causes Of Eero Blinking Yellow
Understanding why your Eero is blinking yellow can help you fix the problem faster. Here are the most common causes:
- Loose Ethernet Cable: The cable connecting your Eero to your modem or another device isn’t plugged in all the way.
- Faulty Ethernet Port: Either the Eero’s port or your modem’s port may be damaged or malfunctioning.
- Damaged Ethernet Cable: The cable itself could be broken, frayed, or internally damaged.
- Incorrect Setup Sequence: Connecting cables in the wrong order during setup can trigger the yellow blinking.
- Network Loop: Plugging both ends of an Ethernet cable into the same router or switch can cause a loop and the yellow light.
- Firmware Update Issue: Rarely, a failed update can cause the device to misread its Ethernet status.
- Router or Modem Problem: Sometimes the issue is not with the Eero, but with the device it’s connected to.
A study by the Wi-Fi Alliance found that about 12% of home networking issues are caused by simple physical connection problems—like loose cables or damaged ports. Eero’s yellow blinking light is designed to help you spot these issues quickly.
How To Troubleshoot Eero Blinking Yellow
Let’s walk through the most effective steps to fix a blinking yellow Eero. Start with the basics and move to more advanced steps if needed.
1. Check All Ethernet Connections
- Unplug and firmly replug both ends of the Ethernet cable.
- Make sure the cable “clicks” into place in the Eero and the modem/router.
- Try a different Ethernet port on your modem or switch if available.
2. Inspect The Ethernet Cable
- Look for visible damage: Cuts, bends, or fraying.
- Test the cable with another device (like a laptop) to see if it works.
- Replace the cable with a new or known-good one if you suspect damage.
3. Power Cycle Your Devices
- Unplug your Eero, modem, and any switches or routers.
- Wait about 60 seconds.
- Plug in the modem first, wait for it to fully start up.
- Then, plug in the Eero and wait for the lights to stabilize.
4. Avoid Network Loops
- Make sure you’re not connecting both ends of the same cable to the Eero or another device. This can confuse the network and cause the yellow light.
- Only connect the Eero’s Ethernet port to your modem or another network device as directed in the setup instructions.
5. Check For Firmware Updates
- Open the Eero app on your phone.
- If you can connect, go to Settings > Software Updates and see if an update is available.

7. Factory Reset (last Resort)
If all else fails, you might need to reset your Eero:
- Hold the reset button (usually on the bottom) for about 15 seconds.
- Wait for the lights to change, then set up your Eero again using the app.
Important: Resetting will erase your settings, so only do this if you’ve tried everything else.
How Eero Status Lights Work
Eero uses a simple, color-coded light system to communicate with you. Knowing what each color means can save time and frustration.
| Light Color | Status | What to Do |
|---|---|---|
| Solid White | Normal operation | No action needed |
| Blinking White | Starting up or updating | Wait for it to finish |
| Solid Blue | Setup mode | Begin setup in app |
| Blinking Blue | Ready to connect | Pair with the app |
| Solid Red | No internet | Check internet connection |
| Blinking Yellow | Ethernet issue | Check cable and port |
Most users only ever see the white and blue lights, but knowing what yellow and red mean helps you fix problems faster.

Common Mistakes When Fixing Eero Blinking Yellow
Many people try to fix the yellow blinking light but end up making things worse or wasting time. Here are some mistakes to avoid:
- Forcing the cable: Pushing too hard can damage the port or cable.
- Skipping the modem restart: Not rebooting your modem can leave the problem unsolved.
- Overlooking cable quality: Cheap or old Ethernet cables may not work well, even if they look okay.
- Ignoring app messages: The Eero app often gives helpful clues or error messages.
- Resetting too soon: A factory reset should be your last option, not your first.
A non-obvious tip: Sometimes, power strips with surge protectors can cause weird networking problems. Try plugging your Eero directly into the wall for testing.
When To Contact Eero Support
If you’ve followed all troubleshooting steps and your Eero is still blinking yellow, it may be time to ask for professional help. Contact Eero’s support if:
- The yellow light stays on after trying a new cable and port.
- Multiple Eero units are showing the same yellow light.

If you see solid red, the problem is likely with your internet provider or modem. If it’s blinking white, just wait—it should go away when the update finishes.
Preventing Eero Blinking Yellow In The Future
While you can’t prevent every problem, there are steps to reduce the chances of seeing the yellow blinking light again.
Use High-quality Ethernet Cables
Cheap or old cables are a frequent cause of connection issues. Invest in a CAT6 or CAT7 Ethernet cable for better reliability and speed.
Secure Your Connections
When you set up or move your Eero, double-check that each cable is fully seated. A loose connection can work for weeks, then suddenly fail.
Keep Devices Updated
Regularly check for firmware updates in the Eero app. Updates often include bug fixes that improve stability.
Avoid Overcrowding Outlets
Using too many devices on one power strip can cause voltage drops. Give your Eero a dedicated outlet if possible.
Label Your Cables
If you have a complex home network, labeling cables can help you avoid mistakes during maintenance or upgrades.
Place Eero Devices Carefully
Physical placement can make a difference. Avoid putting your Eero on the floor or near metal objects, which can interfere with signals and cables.
Real-world Example: Troubleshooting A Blinking Yellow Eero
Let’s look at a real-life scenario. Maria just moved her Eero device to a new room. She plugged it in, but the light started blinking yellow. Here’s how she solved it:
- She checked the Ethernet cable—one end wasn’t fully clicked in.
- After pushing it in securely, the yellow light disappeared.
- Later, she noticed slow speeds. She swapped the cable for a new one, and speeds improved.
This example shows that even small things like a loose cable can create big problems. Always start with the basics before moving to advanced steps.
Eero Blinking Yellow In Different Setup Scenarios
Not all Eero setups are the same. The yellow blinking light can appear in different situations:
During Initial Setup
When setting up a new Eero, the yellow blinking light often means the main device isn’t receiving a signal from the modem.
- Double-check you’re using the correct port on both devices.
- Try a different cable if setup fails.
Adding Additional Eero Units
If adding a second or third Eero, a yellow light can signal a network loop or wrong connection.
- Only connect additional Eeros to the main one if using Ethernet backhaul.
- Never connect both ends of a cable to the same device.
After A Power Outage
Sometimes, after a power cut, devices don’t start up in the right order. This can cause the yellow blinking light.
- Restart all devices, starting with the modem, then Eero.
How Ethernet Quality Impacts Eero Performance
Many users overlook the importance of Ethernet cable quality. Using old or poor-quality cables can cause not just yellow blinking lights, but also slow speeds or random disconnects.
According to tests by PCMag, upgrading from a basic CAT5 cable to a CAT6 or CAT7 cable can improve speeds by up to 20-30% in some cases, especially in homes with high-speed internet. It also reduces the risk of intermittent connection problems that could trigger the yellow light.
Advanced Troubleshooting Tips
If you’re comfortable with tech, here are some extra steps:
- Use a network cable tester to check for broken wires inside the Ethernet cable.
- Try connecting the Eero to a different modem or router to isolate the problem.
- Check your modem’s firmware—sometimes, a modem update is needed for full compatibility.
Pro tip: Some modems have “hidden” Ethernet ports that only work after you call your ISP to activate them. If a port seems dead, check with your provider.
