Here is more info on the end goal. I have several locations, I would like to make an app where when I get on site and join the wifi it looks up the gatway IP address for that location. Once I have the gateway IP I can change the last number on the IP and get the hostname for that IP. This static IP has a hostname containing the location number of the site I'm at. With location number I can then just simply ping known devices by hostname as they are all named with location in the hostname. Once I have the gateway IP and Hostname of a device thats on the network I can then display to the user status info (online/offline) for many devices at this site that should all have static IP's that match the gateway IP but differ by only the last set of numbers in the IP. or by hostname with the location number obtained. I know this is possible, there is currently an app called Network Analyzer that displays the gatway IP. This will just be a personal tool to let me walk onto a site and just instantly be shown any known devices at the location that are offline. The app would do this from getting the gatway IP and figuring out the rest by standardized IP's and Hostnames at each location. FYI (gatway and device IP are different subnets thats why I cant simply use the device IP)

Yes I can confirm that this is the case for me as well. Unusable with battery case on. I guess no one at apple uses the battery case.
