Orbi Router with direct connected devices (mega problems)
I have a new Orbi RBK853 system (wifi6) - sorry but the model dropdown did not find this. Anyway, its 1 router and 2 satellites. Setup over the weekend, no drama. Everything is great. Super fast ...
I've found the problem. These Orbi's (and I guess others) do not play nice with energy efficient ethernet. And what is the default setting for MacOS? Full-duplex, flow-control, energy-efficient-ethernet. Manually changing to just full-duplex for the problematic device has completely resolved the communication issues.
When you say the Mac Mini is connected to the "router", do you mean the ISP router or the RBR?
When the RBR is in AP mode, It would be passing thru all traffic.
You can try a Non managed Gb LAN switch between the ISP Modem and RBR and connect the RBR and Mac Mini to this switch.
The Mac Mini is connected to the RBR.
So Topology looks like:
Fiber Optic into ISP provided Modem / Router - handles DHCP
Connection from ISP router to RBR Router running in AP mode
RBR has two satellites. So Sat1 and Sat2
RBR has Mac Mini and Yamaha receiver connected via Ethernet
Sat1 has no other connections
Sat2 has 2 Synologies connected via ethernet
When I run Roon on the Mac Mini, connected to the RBR via ethernet, multicast traffic seems to not be handled very nicely, or IGMP or something is interfering with it (I have no access to any settings as the RBR is running in AP mode). All settings on ISP router are as they should be.
As I said, everything is working fine - except for the Roon endpoints that cannot find the Roon Core running on the mac mini - the RBR is serving up its own IP instead of the IP of the Mac Mini. Put a switch in between the two and all problems disappear. Putting the unmanaged switch resolves the issue, but I have absolutely no idea why - as this should not be the case...
What happens if you connect the Mac Mini and Yamaha to the back of the main host router and not the RBR?
Yamaha works fine (as two the two Synology's attached to the Satellite)
Have blown away the app, pulled the mac mini from the RBR, hooked it direct to the ISP Router. Reinstalled the app. Same shizzle. It keeps trying to connect to the RBR IP Address (which is the Orbi router in AP mode). I don't get it....
