When to Call a Professional

Contact Eero support if the Thread radio continues to go offline frequently after multiple reboots, if the Eero app shows hardware errors, or if you're unable to access the Eero configuration interface entirely. Persistent Thread radio issues may indicate a hardware failure requiring device replacement.

Frequently Asked Questions

What is Thread and why does my Eero Pro 6E need it?
Thread is a low-power mesh networking protocol for smart home devices. Your Eero Pro 6E acts as a Thread border router, allowing Thread devices like smart locks, sensors, and lights to communicate with your Wi-Fi network and internet.
Will rebooting my Eero affect my Wi-Fi network?
Yes, rebooting will temporarily disconnect all Wi-Fi devices for 2-3 minutes during the restart process. However, this is necessary to reset the Thread radio and restore full functionality.
How often should the Thread radio go offline?
The Thread radio should rarely go offline under normal conditions. If it happens more than once per month, contact Eero support as this may indicate a hardware issue with your Pro 6E unit.
Can I disable Thread if I don't use Thread devices?
Currently, Eero doesn't provide an option to disable Thread on Pro 6E models. The Thread radio runs automatically as part of the system's smart home integration features.
Do all Eero models support Thread?
No, only the Eero Pro 6E and newer models include Thread border router functionality. Older Eero models (Pro 6, 6+, Pro 5) do not support Thread networking.
