When the eero app shows a Beacon as offline, the Beacon has lost its link to the gateway or lost power. Check the LED on the Beacon: a dark LED means no power, so test the outlet; other colors mean it is running and looking for the gateway. Because a Beacon has no Ethernet, it depends entirely on wireless, so a Beacon placed too far from the gateway goes offline when conditions change.
The checks in more detail
Move it nearer, restart the gateway from the app and unplug the Beacon for ten seconds. If the gateway's own internet is down, every unit shows a problem, so check the gateway first. After a power cut, give the gateway a few minutes before the Beacons connect. If a Beacon never returns, remove it in the app and add it again with the plus icon. A Beacon moved to another floor or behind appliances may lose the link.
Check the app for a pending firmware update, since units restart to update. A Beacon that keeps dropping offline in a good position may be faulty. Consider the electrical side too: Beacons plug straight into the outlet and draw very little, but an outlet on a dimmer-controlled or GFCI circuit that trips occasionally will switch the Beacon off, so a Beacon that goes offline after storms may be on a circuit that tripped.
Resetting the outlet's protector or choosing another outlet fixes it. Take a look at what changed before the Beacon went offline: a new piece of furniture, a moved appliance, a new neighbor or a firmware update can all explain a Beacon that worked for months and now fails, and putting things back, or moving the Beacon a meter, often restores the link. Write down the date of the first offline notice to match against these changes.

Model-specific
What is true of this model and not of its siblings
- Wireless only
- A Beacon depends on its wireless link.
- Power cuts
- The gateway must return first.
- Tripped circuits
- Storms can trip a GFCI outlet.
- Dimmers
- They are not suitable for a Beacon.
Stop boundary
When this stops being a self-service repair
- !If a Beacon stays offline close to the gateway, contact eero support
- !If the LED never lights in a working outlet, ask for a replacement
- !Check the gateway first
