First off, I never mentioned the internet, did I?
Second, I thought I was pretty clear but apparently not so I'll try one more time.
There is a finite number of connections any access point or wireless router can handle. Once it reaches it's maximum number, if someone else tries to connect to it, one of the other people already connected gets bumped off it and lose their connection.
The person who gets bumped off rejoins (either automatically or manually) and they in turn bump someone else off. This little merry-go-round continues with pretty much everybody connected losing connectivity, then rejoining over and over again until the number of connected users drops down to a number the router/AP can actually handle.
Ergo what I said above.........spread the number of users over more access points so they can share the load adequately without users getting bumped in an ongoing battle to try to stay connected to the wireless network.
This of course is not including the fact that the more people you have connected to one AP, the slower the network (network NOT the internet) will be for everybody connected. Shared over 3 or more access points, no one AP should be saturated and slow for all connected users.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
