Wi-Fi
2.4 GHz vs 5 GHz Wi-Fi
Understand when to use 2.4 GHz and when 5 GHz is the better choice.
The 2.4 GHz band reaches farther and passes through walls better, but it is often slower and more crowded.
The 5 GHz band is usually faster and cleaner at short range, making it a good choice for streaming, video calls and gaming near the router.
If your device is far from the router, compare both bands with a speed test instead of assuming one is always better.
Quick checklist
- Run a fresh test after changing one setting.
- Compare Wi-Fi and Ethernet when possible.
- Check download, upload, ping and jitter together.
