Controller Based WLANs

If multiple controllers are added to the VIA Controller list of the VIA connection profile, the user can manually select a different controller to establish a secure connection if the primary controller becomes unavailable.
VIA 2.1 clients will automatically switch to a backup controller and do not require the user to manually select the backup controller when the primary controller is unavailable.  If more than one VIA controller is available and if the "enable controllers load balancing" feature of the VIA connection profile is enabled, VIA 2.1 for windows provides load balancing by randomly selecting a controller as the primary controller during each connection attempt.  By default, all other versions of VIA clients will select the controller at the top of the VIA Controller list (available in the VIA connection profile) as the primary controller.
