Being a reseller for couple providers, I always wondered why people bitched and complained about channels buffering, getting kicked freezing etc etc.
I had frontier fios and have never experienced this till today. So long story short, I moved to a bigger place and all they offer is Comcast.
Friend wanted to watch the fight so I went on vod and started it up. After 50 mins or so the fight would stop streaming every 5 seconds. I rebooted, did speed tests and everything was ok. Same issue, froze after 5 seconds. Being a reseller I logged into my panel and could see connection is in red. Disconnected comcast temporarily and connected the firetv directly to 4g lte and no streaming problems at all. Everything was smooth.
Little later today on comcast, was watching discovery channel, same shit after 1hr. Took my device to cousins place, no issues on frontier. Looks like I will have to get a vpn now but it all makes sense finally.
I have the same problem with Comcast. I can start streaming anyone of my few IPTV providers and my stream will start buffering, I switch on my VPN and the streams are usually rock solid. My internet connection is fine when I am doing anything else online.
