Hi, I’m working on a case in our organisation where we encounter regular wireless network disconnections - 30 and 60 minutes. ~ 1800 sec session is widely seen across hundreds if not thousand Macbooks.
We excluded internal wireless configuration issue and vendor specific problem as the disconnections happen on both Cisco and Ubiquiti Access Points.
Wireless Controller debugging most often show EAP timeout error.
Sniffer shows that the disassociation is initiated by Macbook.
MacOS logs show wifianalyticsd performing some actions before the disconnection (generated with sudo log show --debug [time]):

WAEngine and DPSQuickRecoveryRecommendationEngine functionalities (?) play significant role in here recommending Reassociation
We can see that reassociation is being triggered because of DNS symptoms - why and where can I find them?
