Slow RB850

[RSPS1]

I have a new AX6000 with the router and satellite on opposite ends of the house. The house is fairly small, 2400 sq. ft. At the satellite end a wifi strength meter says very high speed, but when I try to download to a devce it says slow connection.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

What device are you using at the RBS? 

What are you trying to download to this device? 

What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

Is Armor enabled on the Orbi RBR? 

What happens if you connect to the RBR? 

I recommend that you need additional help, you should find a nieghbor, friend or family member to help you out with this.
