I just mounted a box with a ROG STRIX X570-E GAMING WIFI II motherboard. I'm not a gamer; one of the reasons I chose this was the build-in WiFi. Bad idea! The thing does not support AP mode, which I need. Nothing in the mo manual suggests such a limitation. Here are the details, in case someone with the same hw has a better experience and would share it. Otherwise, it may be useful as a warning. I know I will not purchase ASUS and/or Mediatek again.
