NG Orbi : Second satellites drops Wi-Fi speed

[whoopa]

Hello,

I have a 200/200 fiber line. My modem is connected with Orbi router and they are in the same place. 

From the Orbi router a UTP (cat6) to a switch (NETGEAR GS105 5-port) from the switch to my second satellite that one is on the 2nd Floor, so its a wired satellite. 

The problem now is when i do a speedtest its stops at 90/40 if do the test at the Orbi router i get my 200/200. 

I added some info about my Orbi.

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 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

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. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).
