Frequently Asked Questions

What does a solid red LED mean on my eero router?
A solid red LED indicates your eero gateway has no internet connection from your modem or ISP. This means the router is powered on but cannot establish a WAN connection to provide internet access to your devices.
How long should I wait after restarting my eero and modem?
After restarting your modem, wait 2-3 minutes for it to fully connect to your ISP. Then restart your eero and wait another 2-3 minutes for it to establish connection. The total process typically takes 5-8 minutes.
Can a bad ethernet cable cause the solid red LED?
Yes, a damaged or faulty ethernet cable between your modem and eero gateway is a common cause of solid red LED errors. Try replacing the cable with a known working Cat5e or Cat6 ethernet cable.
Will factory resetting my eero fix the solid red LED?
Factory reset can resolve the issue if it's caused by corrupted settings, but it won't fix problems with your modem, ISP service, or physical connections. You'll need to set up your entire network again after a factory reset.
Should I contact eero support or my ISP first?
Start by testing if you can connect directly to your modem with a computer. If that doesn't work, contact your ISP first. If direct connection works but eero still shows solid red, then contact eero support.
