I've turned off "SmartSelect" on the Ruckus ZoneFlex 7982 and picked a
static channel. The connection is now more stable, at least no
de-associations today.
It makes me think that rapid or very frequent channel switching by the AP
is exposing a problem in the driver that one would otherwise never see.
