An eero 6 node that shows offline in the app has lost contact with the eero that is connected to your modem, the gateway, and the usual causes are distance, power or a gateway that has changed, and the light on the node says which. A solid white light means the node is working and connected. A blinking white light means it is starting up or syncing, and a solid red light means it cannot reach the internet or the gateway, so it is working but isolated.
The checks in more detail
Start by finding the node's position: the eero 6 is a dual-band mesh with a shared backhaul, which means that nodes lose speed with each hop and are sensitive to distance. If the node is a long way from the gateway, move it closer, to about halfway between the gateway and the room that needs signal, and wait for the light to turn white. Unplug the node for fifteen seconds and plug it in, then wait a few minutes for it to boot. Do the same to the gateway if several nodes are offline, since an offline gateway takes the others with it; check the gateway's light and the modem's.
Then check the power: use the supplied adapter, plug it into a working outlet and not a strip with a switch. In the eero app, open the node's page to see its connection quality and any messages. If the node has been moved or the signal has become poor, the app may advise on better placement. If the node stays red beside the gateway, try restarting it from the app and then removing it and adding it again, using Add or replace eero in the app's settings. The app guides this step by step.
Make sure the eero software is up to date; the system updates itself, but a node that was offline may be behind. Wired nodes need a good Ethernet cable to the gateway or a switch, and a switch port that is faulty can cause drops. Keep nodes in the open and off the floor, away from metal and microwave ovens. If the node will not join after being reset and added again, it may be faulty, and eero support can replace it under warranty with the serial number from the label.

Record this first — changing settings destroys the evidence
- The node's light color
- The distance to the gateway
- Whether other nodes are online
- Whether the node is wired

When this stops being a self-service repair
