This is exactly the problem that I referred to in my recent post of 9/18
("More fun with RADIUS"). We are working on adjusting the power levels and
channel assignments of the various APs in the problem areas to cut down the
frequency of these roaming events. Our reauth times don't appear to take
that long at all, probably because all of our APs tunnel back up to a WLSM,
so all the authentications appear to come from there as far as the RADIUS
server is concerned.
