Why Do Devices Fail To Connect When Using Fast Roaming?

The Fast Roaming feature is based on the 802.11r roaming standard, which requires both the router and the client to support it to take effect.

Some wireless clients don't support the 802.11r roaming standard and couldn't recognize the 802.11r related information in the Beacon frames broadcast by Deco either. In this case, you may find that these clients may fail to connect to Deco's Wi-Fi network or disconnect from Deco's Wi-Fi network after turning on the Fast Roaming feature.

If some of your clients have a Wi-Fi connection issue, it's suggested to disable Fast Roaming for a try.
