buffering problems

I modified this thread as I was unaware of the my [/size]wrong doings but am now !!! So……New octacore 16mb/2gb box/fibre optic supply 50mpbswifi and 100+mpbs ethernet … samsung 49 TV…. NEW INSTALL of Kodi Jarvis with all the simple stuff .. I have managed to sort a good selection of bread and butter addons to watch TV in Spain with Unlocator working well on a posh router ….but I still get buffering quite regularly and wondered if I have missed an Addon that helps resolve this problem… .. please help if you can ! I am a newbi but learning fast (as I like free telly)
