I've had the QNAP TS-253A (still running 4.2 because some other apps I use don't work on 4.3) for almost two years and have maxed out the memory to 8GB. For the longest time, everything was fine. Now, when I am using the Plex mobile app while out and streaming from my NAS at home, the transcoding is taking a lot longer than it used to. This just started happening in the last week or so. It's to the point where I can't even watch a 720p 30-minute show without having to stop to buffer for minutes at a time every couple of minutes.
Is there any advice on what to check? I could be wrong, but I don't believe it's my upload bandwidth at home as nothing has changed with my plan. I am also streaming from the same places I have for years so I don't think it's my phone's network connection. I have set the transcode settings to Automatic and Very Fast in Plex.
And as of this moment, trying to stream will buffer very slow, then after a minute or two the video buffering will just reset and spin without doing anything.
Anyone else experiencing this, or have any ideas on what I can check or do? Any help would be appreciated!
