I, too, have heard about that best practice of using different
channels for different AP's on the same SSID. As far as I can tell,
This is standard textbook stuff. Read Cisco press's 'Deploying License
Free Wireless Wide-Area Networks' by Jack Unger.
it's BS. I don't know who started it, but it has never worked in any
of the situations I've encountered. In fact, I know of at least one
AP manufacturer (Apple) that has a utility to auto-configure WDS
networks, and it auto-configures to use the same channel. That's
Using the same channel is bad, because the APs will interfere with each
other and your throughput will be reduced. Imagine if you have a total
of 2 APs with 10 clients each, the bandwidth will have to be shared
amongst the 22 devices. So, if you're able to get 54Mbps on that
channel, the net result is everybody gets 54/22 = 2.45Mbps each. Not a
very pretty sight.
Roaming with multiple APs on the same channel is OK for small set ups.
