We use an open network that we turn on during deployments to allow new machines to contact Apple's activation servers. I've run into several iPads that are on IOS 9.x that are unable to even see that network but are able to see and connect to our secure network if we input the password. We cannot continue that because we don't want to give out the secure password, and the iPads get it as part of the configuration. Has anybody else run into this issue? Or can you suggest a better method for the iPads to connect to the activation servers?
