WDS is a bad idea for anything more then two APs. Sure, you get basic
roaming functionality and eliminate the usual problems with repeaters,
but performance goes down the drain.

With WDS, throughput get cut in half with every node you add (rough estimate).

And with WDS, you still de-associate from the old ap and re-associate
with the new ap, so it's not really _true_ roaming anyway...

If you have the option [of using cables to the aps], always go with
stand-alone APs instead of WDS. Use the same channel and the same
SSID, preferably with little overlapping coverage areas (so clients
can roam, too much overlap= performance goes down) and you get the
same functionality as with WDS with no performance loss.

But if you don't have a choice (cabling too expensive, not feasible,
on a budget etc etc..), WDS is a good option.
