Aren’t most streaming devices limited to ethernet cable speeds of 100?
My speeds used to be faster than they are now. I was getting very frustrated with buffering on mainstream IPTV channels like ESPN. I contacted my IPTV people and complained and presto, the next day the channels I complained about were solid. And I don’t know why, but after about a month they started buffering again. I think most buffering and connection problems are on their end. Wish I knew which IPTV provider you use, but I think that info isn’t supposed to be shared here(?).
