Fixed! Lenovo Thunderbolt 3 Dock Gen2 screen going blank and USB devices disconnecting – Solution!

For anyone who has a Lenovo Thunderbolt 3 Dock Gen2, and may have been having problems with the monitors going blank or the USB devices becoming disconnected / disconnecting (in effect the dock crashing and needing to be restarted),

I discovered that this dock is very sensitive to electro-magnetic interference. At home, this dock was right next to my new powerful Wifi6 router, and since I got the router my dock was crashing or disconnecting several times every day.

After locating the dock away from the router, it has been stable ever since. I am using this dock with a Lenovo P1 Gen 2 Laptop.

Wrapping the dock in aluminum foil may also help.
