New Orbi AC 2200 Satelllite Slow

[JayFox]

I have Xfinity 400mbps service and just purchased the Orbi mesh system to get wifi in my garage.  My speed near the modem/router combo is at about 100mbps, and out in the garage using a satellite at the halfway point (approximately 12 yards from the modem) is only 30mbps. This feels really weak, anyone have a suggestion as to what might be going wrong?

What Firmware is currently loaded?

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials when wirelessly connected.

Whats the building materians comprised of? 

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

Thanks so much for your help.  I'll try your suggestions. In the meantime, my home is 1300 sq.ft.  Older construction with plaster walls.  We have 7 nearby neighbors with wifi.

I'm trolling the self help articles, but am not sure where to get instructions for trying all of your suggestions.  This may take a while....
