![]() So maybe it's an iP issue, if it starts its check-in from one IP, but gets cut off. I dug into the timing on one device that stopped communicating, check in started just before the student left home for school, connection was cut off in the middle of the process when the student left home to catch the bus. I believe it's communication/network drop at some critical stage during normal iPad check in. ![]() We're seeing last check in dates as early as a few days to a week prior to IT being notified of a student having an issue. We've had additional iPads come up with this check-in issue operatically over the school year. I do this specifically to avoid enrollment issues due to poor connectivity and/or roaming glitches. I enroll all devices in a controlled environment on a dedicated access point and network. I agree it's a communication issue, but I know for sure it's not during the enrollment stage, at least here. ![]() (this also makes me fear there are far more than just the two out there in use right now) It stopped communicating two weeks ago, I'm only hearing about it now because the student is missing an app for a class and it won't download from self service. This is an iPad 8 on iOS 15.6.1 other then the lack of MDM connectivity, the iPad is acting fine. ![]() but if an interruption causes an iPad to stop communicating completely, that's a definite issue. In the past I've seen single apps get stuck when the connection is interrupted requiring a delete and re-install, no biggie. I wonder if something about having the network connection interrupted is the issue. I did note on the second one, inventory update started at 6:43 AM on a school day at an external IP address, and last completed command was at 7:58AM, school starts at 8:10AM, student lives 10 min away. ![]() tried on internal and external networks just in case it was us. What I find odd is they'll request an app from self-service just fine, I see the request come up in JAMF, but it just sits there pending just like every other request. This just started occurring for us, I've gotten two out of 4000 devices so far that just refuse to check in or download apps. ![]()
