Good day.

Thank you very much for your time and patience.

You could think fast roaming is the roaming between Deco units themselves and they would choose which uplink Deco is connected.

For the Mesh Technology, it is the roaming between the client and the Deco unit.

But they just ‘provide’ suggestions and ‘advise’ which Deco is much better to get connected and would have better performance.

As for whether the device would listen to this advice and switch to another Deco could not be determined by Deco but the device itself.

Thanks a lot for your understanding and support.
