Ruckus R510 - Connect to Specific AP?

[TinkyPeanut]

Good Evening All,

Wanted to pick your brains. I have a pair of Ruckus 510 APs in a Lennar Smart Home. One is upstairs and the other downstairs.  The downstairs AP is set as the Master. 

We have 2 devices that are downstairs (XBox and Apple TV) that default their connection to the AP upstairs rather than the one downstairs. It is causing connection/signal issues, especially with the XBox. 

Is there a way to force a device to connect to a specific AP?. They will connect to the Master AP when I reboot the other, but as soon as it is up and running they switch back. 

I’ve been struggling with it for a few days.

Thanks for any help you can lend.
