RBR50 router with Wi-Fi 6 satellite over ethernet

[Alf1122]

I have today a rbr50 router with 2 satellites (rbs50) and need to add another one wired with cable as the distance is to far for WiFi signal. Is it possible to add an WiFi 6 (for example rbs850) orbi satellite? 

Reason is that I want to change to WiFi 6 later but for now the system I have is ok.

No. Not compatible. 

RBS20, RBW30, RBS40v are compatible. Also EX7500, 7700 and 8000 extenders are as well.
