Only thing I'll throw in is that a couple posts define an AP as a device that allows you to connect to a wired segment. That's certainly a capability however a wired segment is not a requirement. You can have a completely wireless infrastructure if you were fine with a contained LAN, no WAN (internet) access, and relatively slow transfer speeds. Also, while I reckon it would be easy enough to do, and there certainly may be some out there, I haven't seen any AP's with LAN ports on it unless it was integrated with a router. The term wireless hub derives from the method that AP's communicate with the clients. Broadcast CSMA and shared bandwidth like a hub. Calling an AP a wireless hub is completely appropriate. Now calling them WAP's on the other hand............😉
