Not getting a strong 5ghz signal from Orbi

Your results look strange. Wherever you were when you made this measurement, you were seeing very weak signals on 2.4 GHz for both the router and your satellite. That would indicate poor coverage in that test location.  Yet, you show -46 for the guest on 5 GHz.  That doesn't make sense at all.

I'd suggest moving positions and repeat the measurement. If you suspect one of the units is not broadcasting one of the SSIDs, then move close to that unit and test. 

Also, you should only be using channels 1, 6, or 11 for 2.4 GHz, so I'd recommend changing channel settings there as well.

I have an Orbi pair with RBR50 and RBS50.  The Guest wifi is booming through at 5GHz but the private wifi seems to be weak in areas.  Having done some analysis it seems as though one of the units isn't transmitting the private network on 5GHZ as can be seen from the attached picture (Guest network seen at -46dB [Strong] and -78dB [Medium] but Home only seen at -77dB [Medium]).  You can see that all signals are visible at 2.4GHz.  Does anyone have any ideas?

Probably issues with the firmware - what firmware do you have?
