Can we use ethernet backhaul and wireless backhaul simultaneously?

[Doritos]

I have an RBR40 Orbi router with a RBS20 satellite and 2 RBW30 wall plugged satelites.

Rightnow, they are all using wireless backhaul.

With OrbiOS 2.1, I see there is support for ethernet backhaul.

I can run cable between my RBR40 and RBS20 - so I can take advantage of the ethernet backhaul feature.

But when I do that, will my RBW30's continue to work in the Orbi network (using the wireless backhaul)?

Thanks in advance.

Went ahead and tried the setup and it appears to be working.

RBS20 connected via wired and the other wall plugged units via wireless backhaul.

But Attached Devices seem tempremental. It keeps indicating one of the wall plugged is disconnected from time to time (intermittently).

I have verfied that the connectivity with devices connected to that unit and they are working fine. The status page on the satellite iteself appear to be working as well.

So seem to be a quirky attached devices in this setup. But I can live with that. Hope its addressed in future updates.
