answer:I find that the non-overlapping ones are more reliable. Remember, you want your signal, and other transmitters on the same channel can make your signal harder to get when you’re picking one of the many on the same channel. With that in mind, I generally use 4, 5, 8 or 9 as those are the ones that I rarely see used when I fire up Wifi Analyzer on my phone. Trust me, having your own channel is useful. FYI, the reason most use 1, 6, or 11 is just that those are default settings, and few people change them. Most people just plug-and-go, while some of the smarter ones set up a password, but few bother changing channels.
