Questions about this test

How much speed does 4K need?

Netflix recommends 15 Mbps for 4K, YouTube about 20 Mbps, and 25 Mbps is a safe figure that covers high-bitrate content. Multiply by the number of TVs streaming at once.

Why does Netflix buffer when my speed is fine?

Consistency matters more than peak speed. If the consistency score here is low, Wi‑Fi interference or congestion is likely. Try 5 GHz, move the router, or wire the TV.

Does the TV's Wi‑Fi matter?

Yes — many TVs have slow 2.4 GHz-only Wi‑Fi. A cheap Ethernet cable to the TV or a streaming stick on 5 GHz fixes most buffering.
