Frequently Asked Questions
Why does DNA 5G buffer when speed tests show 300Mbps?
Speed tests measure aggregate file transfer over multiple streams. Live IPTV requires steady, low-jitter delivery on a single continuous stream.
What is bufferbloat on 5G?
Bufferbloat occurs when cellular routers excessively buffer data packets, causing latency to spike from 20ms to 400ms.
