Question 1

Why does streaming buffer despite having high internet download speeds?

Accepted Answer

Streaming buffering is rarely caused by raw bandwidth limits; it is predominantly triggered by router bufferbloat (packet queue latency spikes), unoptimized player buffer sizing (ExoPlayer cache underflows), or ISP DNS throttling.

Question 2

How does BufferFixer verify technical troubleshooting guides?

Accepted Answer

Every guide is tested in our physical diagnostic lab on genuine hardware including Nvidia Shield Pro, Amazon Firestick 4K Max, Apple TV 4K, and Ubuntu Nginx reverse proxies with Wireshark packet captures.

Question 3

What is the best DNS resolver for streaming video playback?

Accepted Answer

Cloudflare (1.1.1.1 / 1.0.0.1) and Google Public DNS (8.8.8.8 / 8.8.4.4) provide the lowest loaded latency and fastest Anycast resolution, bypassing sluggish regional ISP DNS caches.
