If you live in a crowded environment, leave the 20/40mhz coexistence enabled.
Reason why is if you disable it, your 2.4ghz width goes to the 40hz wide. Which will potentially give you faster speeds.
Problem with it is in a crowded environment, is it overlaps even more channels than the 20hz wide does. Meaning it causes interference for more people as well as it has to scan those channels to broadcast and so it can also increase you ping considerable as it has to wait as theres more channels that might be broadcast on. So it might speed you up a little, but it causes more issues for others and can increase your latency.
If you lived in an area without much for 2.4ghz signals, I'd definitely say disable it. But in a crowded environment, its being the neighbor who always has their stereo cranked and is bothering others.
