RBS850 Satelite 5ghz wireless mode is only 2167Mbps

[farmrt88]

When checking the status of my RBS850 satelite, the 5Ghz wireless mode is only showing 2167Mbps. Firmware has been updated to V3.2.16.22 (old screenshot below).

Any reason why this isn't the full 2400 Mbps? Could this be caused by lower backhaul connection speed between the RBS850 Satelite and RBR850 router?  Is it possibly a UI Bug, or caused by channel interference?

What is everyone else's reported 5Ghz wireless mode from the RBS850 Satelite?  

Thanks!

Has a factory reset and setup from scratch been performed since last update?

What is the size of your home? Sq Ft?

What is the distance between the router and satellite(s)? 30 feet or more is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected can be a factor in reduced connect rates. Thus nature of the beast.
