- Restart the router, modem, and hub in that order, waiting a minute between each.
- Move the hub to a more open location with better Wi-Fi signal if it currently sits in an enclosed space.
- Check the hub's power adapter and outlet, trying a different outlet if possible.
- Look for a firmware update in the hub's app and install it if available.
- If the hub's status light shows a specific error color, check the manufacturer's guide for what that color means.
