Optimizing for top speeds is the wrong way of looking at this.
Even the shittiest consumer WiFi will generally give a satisfactory speed test result with decent speeds, despite being completely unusable for anything real-time like video conferencing, Remote Desktop or gaming. Your random high-speed result may very well be down to luck and doesn’t represent how stable and usable the connection will be.
In fact what the author does here (crank up the channel width, etc) might do for a good speed test result but will start dropping out with terrible latency spikes and jitter the second he turns away from his WiFi AP.
Smaller channel widths are generally preferable as they provide a smaller top speed but said speed will be much more stable.
Sure. Those are also things I optimize for. I'm using 40mhz 5ghz channels and 20mhz 2.4ghz channels. I'm in the 'burbs, but silicon valley, and small lots, so there's definitely some contention for channels. Just sharing my experience.
