Menu labels and LED meanings can vary by model and hardware version. Keep the product label and official manual available while following this guide.
1. Identify which devices are affected
A red eero status light indicates it is offline; check the gateway first, then upstream Internet and cabling.
2. Check Internet and local login
If a new eero is not found, move it closer, confirm Bluetooth and app permissions, and restart the setup flow.
3. Restart the network in order
Avoid daisy-chaining through poor wireless links when Ethernet backhaul is available.
4. Update, reset or restore carefully
When the modem is replaced or restarted, allow it to come online before rebooting the gateway eero.
5. Escalate model-specific faults
Record the model, hardware version, firmware, LED state and tests completed before consulting the official support channel or ISP.
