I have a problem and I can’t figure it out.  Just picked up Fire Stick 4k to replace my 2[sup]nd[/sup] Gen fire stick.  I had the issue on my 2[sup]nd[/sup] gen as well.  Worked fine for a year so then this started happening.  The video will freeze for about 15-20 seconds then go really fast for 5 seconds play like normal for 10-20 minutes then do it again. Updated kdoi to 17 still had the problem.  Ok the 4K Stick I upgraded to 18 RC3.  It still does the same time.  I have checked buffer settings (currently set to 3)  turn software and hardware codec on and off.  No change.  What could I look at to fix this?

Here is my Setup.  Firestick 4k with Kodi 18 RC3, Files stored on Network NAS (WDTVlive Hub) hooked into a Linksys switch upstairs that has a wire connection to my main Linksys Router downstairs that my Firestick is wireless connected to.  All gig switches.  The video files are 720p.  Netflix and Amazon stream just fine.  Any Idea what to try?

All my settings are default FiresStick 4k & Kodi RC3.

Thanks
