2.4 GHz and 5 GHz frequency management
Modern routers often operate in two ranges: 2.4 GHz and 5 GHz. Range 5 GHz provides higher data transfer speeds, but has a shorter range and is worse at penetrating walls. Range 2.4 GHz slower, but works more stably at a distance and in noisy airwaves.
On smartphones Samsung Galaxy Recent models often switch between frequencies automatically depending on signal strength. However, if you want to force a specific frequency, you may need to access advanced settings. Some firmware versions hide this, but you can try finding the "Wi-Fi Band" option in the advanced Wi-Fi settings menu.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Speed | Up to 450 Mbps | Up to 1300 Mbps |
| Range | High | Average |
| Permeability | Good | Low |
| Workload | High | Low |
If your router broadcasts one network with the same name for both ranges (technology Smart Connect), the smartphone will decide for itself where to connect. In this case, you can only influence the choice by moving closer to the router (for 5 GHz) or further away from it (for 2.4 GHz).
⚠️ Note: The frequency settings interface may differ depending on your router model and smartphone firmware version. If you don't see a band selection option, your device is using automatic mode.
Troubleshooting connection issues
