2.4GHz vs 5GHz WiFi — Which Should You Use?
Both bands have trade-offs. 2.4GHz travels further but is slower and more congested. 5GHz is faster but has shorter range.

1
Understand 2.4GHz
The 2.4GHz band reaches further and penetrates walls better, but is shared with microwaves, baby monitors and many neighbours' routers — so it's often crowded and slower.
-
2
Understand 5GHz
The 5GHz band is much faster and less congested, but its signal doesn't travel as far or penetrate walls as well. Best for devices close to the router.
-
3
Choose 5GHz for speed-critical devices
Laptops, streaming sticks, and gaming consoles near the router should use 5GHz for the best performance.
-
4
Choose 2.4GHz for distant or IoT devices
Smart home devices, sensors, and anything far from the router should use 2.4GHz for the better range.
Frequently Asked Questions
Should I use the same name for both bands?
Modern routers with band steering handle this automatically. If your router is older, giving them different names (e.g. Home and Home_5G) lets you choose manually.
What about 6GHz (WiFi 6E)?
WiFi 6E adds a 6GHz band for even faster speeds at close range. It requires a WiFi 6E router and compatible devices.
