The ChannelFly dynamic channel management technology in Ruckus APs improves wireless performance by dynamically switching a client to a better channel when the one it’s using starts to degrade. Unfortunately not all client devices can understand Channel Switch Announcements (CSA) coming from AP and as the channel changes, they simply loose the connection and have to connect anew.
Beginning with SmartZone 22.214.171.124.665, it is possible to disable this feature from the AP command line:
set csa_count wifi<xx> 0
Note: <xx> represents the radio interface, for 2.4GHz it is wifi0 and fot 5GHz it is wifi1.
