I helped a friend of mine install kodi not running iptv or anything but here at my place it ran flawless never buffered here I had the box for the weekend now he has it at his place and he says it buffers all the time, I think connection speed mayb I mean if my kodi screws up here it either freezes or flat out shuts down so I don't really know what to tell him thought mayb some one here may have some helpful input , I know a lot things can play a part in buffering traffic, ntereference , speed so on I really don't know what to tell him..
