Intelligent Wifi Channel Selection

My apologies up front if you landed here (thanks G) seeking for an algorithm for automated wifi channel selection. This is a very basic rant.
The internet router has a setting to avoid overcrowded channels. By setting it to decide on the auto channel, it is supposed to choose the one which is the least crowded. The problem is that there are other routers on the air doing the same thing. The end result: they end up in the same channel. (Well, I think they all are of the same kind.)
Here is a photo proof:
16 of them selected to be at 11, probably because all of them at some point figured that 11 was the best one!

Clearly, the plan is self defeating. A general advise on channel selection (word of mouth) is that channel 5 and 10 are usually crowded: "avoid them!!"
Well, if I am not wrong, after repeated tests (figures not included), I can conclude that the above statement is wrong!

Therefore, I have decided that it is not optimal anymore to let it auto select the channel. Because according to the game theory, they would play the same (defeating) game. The result is shown above where they love channel 1 and 11, which are supposed to be least attractive.  By going into a set channel, say 10, or 2 or 5, or 8, whatever, you know what you are going for.

Have you set your router to an intelligent wifi channel selection?
