Martin,
Interesting. I knew there were issues for 802.11ax in the ISM band outside of the ones currently used for wifi, but it seems the issues extend to the current 5GHz band as well.

There are legal restrictions on spectrum use, especially in the 5Ghz
range. Which means additional effort must be put into both hardware and
software to satisfy those restrictions. And perhaps that effort was not
considered cost effective for the AX200.
