Specifically in Sao Paulo, London, and Tokyo.
I have tried all of the different streaming speed options, with and without VPN’s (tried 3 different ones) and the best I get is an occasional stuttered picture on my iPad Pro.
All 3 of the cities had above average internet speeds. UPnP is enabled.
Any other suggestions?
I have used OTA2go well connected to my home network using a VPN. It’s meant to download shows before you leave home but it worked equally well for me to download shows after I left home. That way the whole show is cached on your device. Unfortunately it won’t allow you to watch live TV.
EDIT: I have never had an issue streaming from outside the house using the regular Tablo app. If I were you I would test my upload speed at home and wire my Tablo via physical network cables. A VPN should not be needed at all in most cases. Perhaps your local ISP is traffic shaping.
Have you tried altering the Remote streaming quality options to see if it has any impact on performance?
