A red light means the Eero can't reach the internet. Here's how to diagnose and fix it in under 10 minutes.
After a power outage or deliberate restart, if the Eero powers on before the modem has established an upstream internet connection, it will show red. The Eero needs to detect an active connection on its WAN port before it turns white.
The cable connecting your modem to the Eero's WAN (internet) port may have come loose, been partially unplugged, or developed an internal fault. This is especially common after moving furniture or vacuuming near the equipment.
Your internet service provider may be experiencing a local outage or scheduled maintenance. If your modem also shows no internet connection, the problem is upstream of your home network entirely.
If the Eero lost power or lost its connection mid-way through a firmware update, it may be stuck in a partial update state. In this case the light may pulse red/white. A factory reset usually resolves this.
Look at the indicator lights on your modem — not the Eero. If the modem shows no internet ("online," "internet," or a similar light is red or off), the problem is upstream. Your Eero is working correctly but has no internet to connect to.
Unplug your modem from power (the small box your ISP gave you). Wait a full 2 minutes — this forces the modem to fully release and renew its DHCP lease with your ISP. Plug it back in and wait until all status lights stabilize.
Once the modem is fully online, unplug the Eero from power. Wait 30 seconds, then plug it back in. The Eero will cycle through colors — give it 60–90 seconds to settle on a solid white light (connected).
Press both ends of the cable firmly into the modem's LAN port and the Eero's WAN (internet) port until you hear or feel a click. Inspect the cable for kinks or sharp bends. If you have a spare cable, swap it in.
Open the Eero app and tap the device showing red. The app often surfaces a specific error (e.g., "No internet," "Double NAT detected," "Upstream issue") that narrows down the cause significantly.
If all other steps fail, factory reset the Eero. Hold the reset button (small pinhole on the bottom or back) for 10 seconds until the light flashes yellow, then white. This erases your network and you'll need to set it up fresh in the Eero app.
