Ah that is good. I was worried about the 5ghz since my r7000 5ghz doesnt even make it one floor above with a workable signal.it depends on the location
in my case, primary and 1 satellite are on ground and 2nd sat on 1st
the ground sat reports between 1000-1300 mbps while the 1st sat reports 1300 steady
(the 1st floor sat is pretty much directly above the ground flr primary)
One thing to note - the India Orbi (as well as any other new router) are region locked to India and the 5ghz tx power in India is capped severely due to regulatory compliance requirements.
I had to change region to global via telnet and bump up the 5ghz band tx power that considerably improved both backhaul and fronthaul speeds
