What to do
- Check the hub's power cable and outlet, and confirm the power light is on.
- Confirm your home internet and router are working for other devices.
- Unplug the hub for 30 seconds, then plug it back in and wait several minutes for it to fully boot.
- Restart your router and modem as well.
- Check the hub's status light against the manufacturer's guide to identify an error state.
- If you changed your Wi-Fi password or network recently, reconnect the hub through its setup app.
- Contact the manufacturer's support if the hub won't come back online after a full power cycle and confirmed working internet.
