Where are my wired devices?! RBS850

Hello,

I recently purchased and setup an RBS850 system. One satellite. I'm having some strange difficulties with ethernet-wired devices to the satellite. They are getting DHCP addresses, and are reachable (great!) But they neither show up in Orbi's "connected devices" list, nor if I log in to the satellite's admin UI do they show up. 

But I can see they are connected and functional. I can VNC and access them just fine. But I search for the IP in either gui under registered devices, and nothing. On my satellite, which has 3 ethernet connected devices, 2 of which I have verified have an IP and are fully functional, it shows.. one wired device with no IP address. 

This creates difficulties in reserving IP addresses for those devices. It's quite.. odd.

Has anyone encountered this behavior, and if so, what did you do to resolve?

Thank you
