We have a new deployment of Surface Pro 4s, running Windows 10 1607 with the Marvel AVASTAR driver version is 15.68.9040.67, we have a mix of 3710 and 3825 APs running 10.21.04. We're seeing a problem where a student's device will remain associated to the network, but loses IP connectivity. Annoyingly it fixes itself after 5-10 minutes so I haven't been able to get a good look at the problem. I'm trying to get a capture with
but what other troubleshooting commands should I be trying?
