Twitch TV live streaming video buffering?
Live streaming Twitch TV, Sling TV, and other similar HD video content strains broadband connections a lot more than other uses of your internet connection, such as browsing, playing games, streaming audio, etc.
The culprit could be issues with your local wireless network, but, often times it the cause is in your TCP/IP network settings, and the connection to your ISP.
We have a free tool, called the SG TCP Optimizer, that helps tune your TCP/IP settings by optimizing all related network parameters on your end to reduce lag and ensure buffer-free connection, at least as much as possible given the bandwidth your ISP provides. It works with most Windows PCs, starting with Windows XP and up to the latest Windows 10 builds.
