FAQ
Questions
Is 100 Mbps enough for 4K?
It can be. One 4K stream typically needs far less than 100 Mbps. Count simultaneous screens and leave headroom.
Why is my speed lower on Wi-Fi?
Walls, distance, radio interference and the device itself affect the result. Compare a wired reading with one at your seat.
