Wi-Fi networks that don't require a certificate that have been added to your Network Library can be assigned to headsets you manage.
To assign a Wi-Fi network to a headset or group of headsets:
From Device Manager, click Device Fleet.
Click the headset or group of headsets you want to add a network to, then click Add Network.
Under Network Library click the dropdown menu and find the network you want to add.
Click Add Network.
To add a certificate-based Wi-Fi network to a headset, you'll need to use MDM.
