[Q] Plex Media Server issue with SG3 gallery

view story

http://forum.xda-developers.com – I'm running Win8 and for my LG tv I have installed PLEX media server on my PC, so when the Plex is running my SG3 is having issue to open the gallery, it's opened but not responding at all for 5-10 minutes, and after that gallery is slow, if I close Plex, gallery opens in 2-3 sec. I think its syncing my PLEX files, but how to stop that. GS3 running stock 4.2.1 UK BTU firmware, no root no modification at all, pure stock. Is there any fix for this, or I need to turn off my wifi or Plex to have gallery running well. (HowTos)
