Not exactly Jamf-related, but I'll toss this question out to the knowledgable masses. We are seeing some Macs losing all connectivity on our 802.1x Wifi. The computers have valid IPs and show that they are authenticated on 802.1x, but all pings (to & from and internal & external) fail. I got our network team involved and they show that the Macs seem to be repeatedly authenticating throughout the day. When a Mac is in this dead state, they show that everything on their end looks 100%. They can snap a Mac back into communicating by sending a command from their console to reauthenticate. In the /var/log/wifi.log file, often times it does not indicate any sign of trouble or activity at all at the time of the disconnection. There was one time I got the following line from the log at the exact timestamp the issue happened:
Mon Sep 30 09:54:15.138 <kernel> IO80211AssociationJoinSnapshot::captureRequestCallback Problem reported from corecaptureOther than that, there's no logged indicators of problems. In addition to the network team being able to force a reauthentication, we found that the simple act of disabling Wifi and enabling it again will restore connectivity. It seems that these problems started when we began upgrading to Mojave. Many of the affected Macs are updated all the way through 10.14.6 w/Supplemental update 2. Has anyone else experienced this kind of problem since going to Mojave?
