Note: OnHub routers are not compatible with Google Nest Wifi.
If you have an OnHub, it is recommended to use it as the primary Wifi router in your network, then adding Google Wifi points to expand coverage. Learn how Google Wifi works with OnHub.
How to switch primary Wifi point
If you've already set up a Google Wifi point as the primary Wifi point and want to make your OnHub the primary Wifi point, you will need to factory reset both the Google Wifi point and OnHub. Then, restart set up with the OnHub as the primary Wifi point, and then add any Google Wifi devices as mesh point(s).
Create mesh Wi-Fi network with multiple OnHubs
If you have multiple OnHubs and want to create a mesh Wi-Fi network with them, it's possible. You can set them up in the Google Home app. First, add one OnHub as the primary router and then add other(s) as mesh Wifi points.
