An eero system has one gateway unit that connects to the internet line and other units that spread Wi-Fi. eero's support pages say the gateway needs an Ethernet port, a power cord, an Ethernet cable and an internet connection. The company's page itself returned a server error, so check it directly if a screen differs.
Steps
- Install the eero app and create an account
Do this first so the app is ready when the unit lights up.
- Disconnect the old router
Unplug the cable that goes from the High Desert injector to your old router. Leave the injector powered.
- Connect the injector cable to the gateway eero
Either Ethernet port on the unit works, per a summary of eero's support text. Your High Desert service arrives on the Ethernet cable that leaves the indoor power injector; it plugs into the router's internet (WAN) port.
- Plug in the gateway eero
Wait for the light to show it is ready for setup. The app tells you what the colors mean.
- Follow the app
The app detects the gateway, then asks you to name the network and set a password.
- Add the other eeros
The summary says extra units can connect by Wi-Fi or by Ethernet, and Ethernet is more stable. The app guides placement.
- If the app reports no internet
Restart the injector, wait for its light, restart the eero, and try again. Then call 775-575-9593. A summary of eero's support text says some providers need special configuration, so ask us before you change any advanced setting.
Does eero need a modem?
A summary of eero's support text says eero works with a modem, a fiber terminal or other upstream device, as long as an Ethernet cable can reach the gateway. For High Desert, the upstream device is the power injector, not a modem.
Does eero have a subscription?
We do not publish eero's prices, and none of this page depends on one. Check eero's site for what its plans include.
Where do I put the second eero?
Place it where it still gets a good signal from the first. The guide whole-home Wi-Fi and mesh covers placement, and Wi-Fi dead spots helps if one room stays weak.
Do I need to go outside or touch the antenna for this?
This task never calls for a ladder. The outdoor radio and the cable that runs to it should not be touched by anyone but our technician.
