What buffles me (I'm just a smallnet builder not a wifi rf-chip designer or a wifi firmware writer), why not a simple comparative benchmark between APs from different generations? Say an AX router with OFDMA on (no need to rely firmware does the best, if OFDMA set on or off, very interesting that tests showed differences between OFDMA on/off and there is a tertiary feature, I think, to switch it on/off as marketing material and publications to be taken seriously tout OFDMA is a silver bullet WiFi6 written on it), an AC router with stock. latest and greatest firmware in it and an AC router with OpenWRT and SQM/Cake in it. All tree put through the same tests to reveal differences in throughput, latency, airtime congestion between STAs and most importantly previous quatities measured under maximum load. - Erkki
