I am running iptv66 with dreamlink t1 dol2 and have noticed a lot of buffering on different channels since after the big server upgrade they did about a month or so ago ...my understanding was that the server upgrade was done to prevent these issues not make it worst I am to the point now that I only turn the server on when ppv fights are on and half the time can't even count on that cause the channels are buffering like crazy and have to rely on something else like kodi...i hope the service becomes more stable like before cause it seems a lot of people aren't happy with this service lately and are going elsewhere
