DS213+ PLEX on IOS terrible playback

[chkoehler96]

Hi,
 
I'm using the DS213+ and running the latest version of PLEX server.
If I play movies on my Samsung TV it's flawless! works great.
But running movies on an IOS device is terrible. First it takes ages to load and when it plays it stops constantly after about 20 seconds, it buffers for 20 seconds and plays for 20 seconds.
I remember that it used to play without any problems like 5 months ago. What changed??? I tried multiple different settings on my DS, PLEX server and client.
I can play movies without any problem on my IOS device using DSVideo, but of course this isn't that nice as PLEX. So shouldn't be the processor of the DS213+.
 
Please help anyone!
 
Regards,
Chris
