LAN dropping Connection to a TV in Mirror Cast periodically
I am having issues when mirror casting from my Lenovo X1 Carbon to a 2 year old Samsung Smart TV. I am able to ge the connection initially and then at some random amount of time the connection will drop and I have to reconnect. The time could be 5 minutes to 30 minutes. This only affects the mirror casting and not the internet connection. I can watch TV on this TV forever without a loss of signal from the router.
Also, Orbi does not list the TV on the list of connected devices at any time. It never shows up.
Help - this is a pain when I am mirror casting from my Lenovo X1 laptop to this TV for business uses.

What Firmware version is currently loaded?
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.
Try enabling Beamforming and MIMO(MIMO may or may not 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).Contact the mfr of this Mirror Casting to see if there is any known information regarding problems with this TV or Lenovo laptop.
The firmware version is 2.2.2.104.
The router, Laptop, and the TV are in the same room and on the same LAN.
I'll try your solution options.

WMM was already enabled.
I have now enabled Beamforming and MIMO.
IPv6 and Daisy Chain, Armor, Circle, and Fast Roaming were not enabled.None of those changes solved the problem.

There appear to be several methods of mirroring a laptop screen to a tv. Could you describe which of these methods is being used:

I'm using the screen casting tool built into Windows 10.

The reason I asked is that Lenovo article says this about the screen casting capability built into Windows 10::
The beauty of technologies such as Miracast is that they don't rely on your home/office wireless network. Instead, signals are transmitted via Wi-Fi Direct, which has a shorter signal range but enables device-to-device streaming without a central router.
This would seem to indicate that the issue has nothing to do with the home WiFi network (Orbi).
