@Rob, Just to clarify - WiFi 6 can help solve your problem if either of the 2 conditions apply to you.

WiFi 6 APs and devices without 6GHz support just start shipping now. WiFi 6 APs and devices with 6GHz support probably won't start shipping until early 2021. So it may takes a few years before full-fledged WiFi 6 products with 6GHz support become mainstream for most folks to get the full benefits.
