Spanning Tree problem with Orbi RBR50
I have been having network problems with my Orbi system for a few months now.. The symptoms are similar to issues others have reported, where satellites and other devices gradually disappear from th...

I would check with the mfr of this device to see if it's compatible. If this one device causes this to happen when it's connected, something with this device needs to be looked at. Ask the mfr if they have tested this with a Orbi system.
Is this the unit?
I don't see any ethernet port support on this unit...Is there a different model unit?
It may be this one?
Regardlelss, if this one device is causing problems, then it mabe best NOT to use it with Orbi. Seems like it maybe a compatbility problem with this one particular mfr device. I have a USB 3.0 C adapter that I use with my mac book and it doesn't cause problems. Thought it's just a LAN to USB C adapter, no additional USB ports.

Your comment is not super useful. The issue is understood, there are apparently USB-C hubs around that cause the network to drop out. To which degree a faulty device should however take down an entire network is something I believe that should be discussed.
In any case it's valuable for others to know that USB-C ethernet hubs indeed do this to your network, at least when an Orbi is included.- FURRYe38Jul 06, 2020Guru
Maybe only with with this one particular brand as well. Maybe there seems to be a incompatibility issue this with mfr. Try a different mfr or try a ethernet to USB C only adapter and leave off the USB ports. I have a couple of ethernet adapters and they work fine with my mac book pro. No USB ports though.

Well possible various "brands" and "no-names" are soldering or OEM labeling such USB-C hubs with Ethernet ports based on some chip vendor sample PCB design, and deploying some basic firmware (there is on most of these devices!).
To keep it simple: An Ethernet adapter without an active controller (the USB-C host) can keep the link up (why ever, e.g. listening for WoL magic packet, ...) but under all circumstances it does not have to cause havoc on the network - regardless if this is STP (we have no proof, right?), reflecting traffic like broadcast, multicast (to much can lead to a port shutdown, too). If it does ... suspect trash.Would be interesting to capture the data on that link. But that's a job for the vendors of these devices.
