I recently purchase a month trial with a provider, everything seemed fine until I tried watch the liverpool v man city match on Sunday. My provider tells me the problem was with my speed. Could my ISP be throttling during time windows of major sporting events as I did a speed test and was getting over 40mbps. Would a VPN help?
I know some say your ISP can throttle but this goes through port 80. That is normal webtraffic. I think you will find out that the provider is being hit hard during that time, which is why you are seeing buffering. A VPN will encrypt the stream but it will also slow you down...so it might even be worse if its not your ISP. Who are you using for your IPTV stream?
