How many computers can I connect to a Wireless access point?

In theory, you can set up 254 computers to one access point. IP addresses 0 thru 255 are assigned for private use, but since the numbers 0 and 255 are assigned as "special" numbers, that would leave 254 addresses available for private use. However, after 20 or 30 computers being setup, the signal becomes so diluted that adding additional computers is just not recommended from a performance stand-point. As a matter of fact, most will agree that no more than 10 should be connected to one access point for optimal performance.
