Honestly, I don't even know why Asus exposes all the settings there with Asuswrt allowing totally contradicting or impossible combinations. Like one can set 2.4GHz in Legacy mode with PMF capable, MU-MIMO and Explicit Beamforming plus Roaming Assistant with a single router... what? On a consumer product this only causes confusion and when something is not working on Default - it's easy to mess things up even more. I also don't know if all the settings even work in different firmware versions. Found some doing absolutely nothing in different firmware and on different models. Most likely reason - changes in underlying Broadcom wireless drivers. Whatever was working before doesn't anymore or vice versa, but still exists in Asuswrt.
