Control AP selection?

Thank you.

In other manufacturers, I've seen the ability to control the the thresholds at which a mobile device will roam from one AP to another. It stands to reason that similar could be used for non-mobile devices.

I'll see if I can judge why non-mobile devices are attaching to the router (as you say, it could just be startup order of the Router / Satellites) but consider adjusting the transmit power if this won't affect the backhaul.
