Thank you for posting in the Slingbox Answers Forums! I apologize for the inconvenience of not being able to connect to your Slingbox PRO-HD via iPad Mini, from a remote location.
Have you tried connecting from more than one remote location? Also, could you go to speedtest.net and tell us the results of your upload and download speed at the location of the Slingbox?
Feel free to reply!
