What Is The Problem Of Netflix Buffering?

Buffering during Netflix streaming on Vizio Smart TVs is a common issue. It’s usually caused by insufficient internet speed or a weak Wi-Fi signal. When your TV can’t receive data fast enough, it pauses the video to load more, leading to buffering.

Your streaming quality heavily depends on your internet connection and speed. Netflix recommends a minimum speed of 3 Mbps for standard definition, 5 Mbps for high definition, and 25 Mbps for Ultra HD content. Buffering is likely to occur if your speed is lower than these thresholds.
