Wi-Fi is how devices connect to the internet and each other without cables. Your router broadcasts a wireless signal, and your phone or PC joins it. Most modern routers use a standard called Wi-Fi 6 (802.11ax) — a newer, faster, more efficient generation than the older Wi-Fi 5.
The two bands
Almost every router broadcasts on two frequencies at once, usually under the same name:
- 2.4 GHz — slower, but travels farther and through walls better. Good for the furthest room or thick walls.
- 5 GHz — faster and less congested, but shorter range and weaker through walls. Best for the room closest to the router.
Many laptops and phones join 5 GHz automatically when you're close and drop to 2.4 GHz when you move away.
Why 5 GHz feels faster
Less of the world is using 5 GHz (microwaves, old Wi-Fi), so there's less interference, and the channel is wider. The trade-off is distance.
If your Wi-Fi is slow or drops
- Move closer, or switch to the band that suits your distance.
- Wi-Fi 6 / 6E routers handle many devices and dense homes better than old ones.
- A mesh system or a powerline adapter beats a single router in a large or thick-walled house.
For gaming and video calls, a wired Ethernet connection is almost always smoother than Wi-Fi. Use Wi-Fi for convenience, Ethernet for reliability.
