eero Beacon will not complete setup

Setting up an eero Beacon is done in the eero app, and the thing to understand first is that the Beacon is only an extender: you set up the eero router, which connects to your modem, and then add Beacons around the house. Plug the gateway eero into the modem with Ethernet, power it, open the app and follow the steps to create the network. To add a Beacon, tap the plus icon, choose Add or replace eero device, and plug the Beacon into an outlet within range of the gateway; the app finds it, and the LED shows its status. Place Beacons about halfway between the gateway and the dead area, in a socket with a clear view, not behind furniture.

Wait for the LED to settle before judging the result. If the app cannot find the Beacon, check that the phone is on the eero network, Bluetooth is on and the Beacon is within a room of the gateway. A Beacon that was set up before must be removed from the old account or reset. Use the app's network speed check to test the placement. Keep the setup account details safe: the eero account email and password manage the network, and a lost account makes changes hard. If you replace the gateway later, the Beacons stay in the account and reconnect after the new gateway is set up with the same account, which saves redoing the whole network.
