How does WiFi work and why is it sometimes slow

WiFi uses radio waves to send data from your router to your phone or laptop wirelessly. The closer you are to the router and the fewer things in the way, the faster and more stable your connection. Walls, metal, distance, and other WiFi networks slow it down.

WiFi is a wireless communication system that works like an invisible radio. Your router broadcasts a signal that your devices pick up and use to talk to the internet. The signal gets weaker the farther you go and when it passes through walls or metal. If many people are using the same WiFi or the same radio frequencies, you get congestion and slowness. Understanding how WiFi works helps you position your router better and know when slow speed is expected.
