To troubleshoot, view the System Info file of the AP the problem client is on
(from Monitor/Access Points, first icon (blue/green) to right of selected AP).
Search for the client MAC in the connected clients tables and evaluate the
RSSI and PER values. High interference can affect client connectivity and
can be near the AP (Athstats) or the Client (PER). Version 18.104.22.168.9 is the
current recommended ZoneDirector firmware. Always try to load latest client
radio/supplicant drivers too.
Try disabling few of the features just for testing to see if that minimizes your issue:
If you are using AUTO channel then fix a static channel on each AP and ensure that NON-over lapping channel are used. You will find this in AP configuration
Also try disabling background scanning or increase the interval to MAX value. You will find this in services section.
Hope this helps.
