I'm looking to collect some other information to help inform our process to resolve an issue we are experiencing on our wireless infrastructure. I have an open incident with my vendor and they are working on a resolution, but I'm trying to determine if we are the only ones dealing with this.
We have a large deployment of iPads (1500) on our campus. somewhat evenly distributed across iPad Air 2, iPad Air, iPad 4 and iPad 3 and almost all are running iOS 8.x. We had an issue crop up this fall when a group of iPads all connected to the same access point all go to sleep at the same time. The access point seems to lose track of which devices are asleep and which aren't and it ends up overwhelming the RF space with RTS packets to iPads that don't respond, thus rendering every other client on the access point almost non-functional. Has anyone seen wireless transmit issues related to iOS "sleep" mode? The packet captures indicate that the iPads seem to oscillate quickly between "sleep" and "awake" and eventually end up asleep will the AP thinks that they are still awake. Obviously, I'm in the middle of a bit of finger pointing between the wireless vendor and Apple and other data points can only help. Thanks, Christopher Christopher Butler Assistant Head of School.
