Hi, I am working on a case in our organisation where hundreds if not a thousand wireless network clients are affected by regular, usually 30 sometimes 60 minute sometime they are unnoticeable but often people having meetings notice that a lot.
We excluded wireless network configuration issue since disconnections happens to clients both connected to Cisco and Ubiquiti Access Points.
WLC logs mostly show EAP timeout errors - clients are getting disauthenticated and authenticated back - usually without any action needed - but the meeting is being interrupted.
What I found in Macbook logs with sudo log show [options] is the main reason of network disconnection:

Do you guys have any idea where can I see that DNS symptoms?
I can also see some reading like:

WiFi Not Primary - how if this is my only interface? - I removed all other
Killing and disabling wifianalyticsd does not help - the process is being spawned by launchd on airportd request:

Do you guys have any idea what is the cause of this behaviour?
Or how to disable wifianalyticsd process for good?
