Hello Matt,
Here is our inline response of your queries-
what is the result of this?
By default we get the captive portal web page if System extension is disabled, but with System extension, captive portal web page is not coming up.
Are users not able to join the network or does it allow anyone to join?
User is not able to access internet if the user is not logged in, which has to be done with captive portal web page. So, user can't browse anything through safari.
are you able to see anything in the system logs when this takes place?
We were able to gather some logs for the same, we are attaching the logs.
We are getting- 'kernel: (2944957949): failed to get a local IPv4 address: 51'
