Configuring the Wireless Array 327
18. Auto Channel List: Use All Channels selects all available channels (this
does not include locked channels). Use Defaults sets the auto channel list
back to the defaults. This omits newer channels (100-140) — many
wireless NICs don’t support these channels.
Station Assurance
Station assurance monitors the quality of the connections that users are
experiencing on the wireless network. You can quickly detect stations that are
having problems and take steps to correct them. Use these settings to establish
threshold values for errors and other problems. Station assurance is enabled by
default, with a set of useful default thresholds that you may adjust as desired.
When a connection is experiencing problems and reaches one of these thresholds
in the specified period of time, the Array responds with several actions: an event
is triggered, a trap is generated, and a Syslog message is logged. For example, if a
client falls below the threshold for Min Average Associated Time, this
“bouncing” behavior might indicate roaming problems with the network’s RF
design, causing the client to bounce between multiple Arrays and not stay
connected longer than the time to re-associate and then jump again. This can be
corrected with RF adjustments. Station assurance alerts you to the fact that this
station is encountering problems.

19. Enable Station Assurance: This is enabled by default. Click No if you
wish to disable it, and click Yes to re-enable it. When station assurance is
enabled, the Array will monitor connection quality indicators listed
