Your wireless router uses radio waves to transmit internet signals to smartphones, tablets, and laptops. The main difference between 2.4 and 5 GHz WiFi is their range and speed. Below is a comparison of both frequencies.
2.4 GHz vs. 5 GHz: Advantages and Disadvantages
| Frequency | Advantages | Disadvantages |
| 2.4 GHz | It covers more area effectively. | Slower speeds. |
| 2.4 GHz | It moves quickly through walls and barriers without much interference. | Easily affected by interference. |
| 2.4 GHz | Compatible with many devices. | Often crowded with connected devices. |
| 5 GHz | It delivers higher speeds for improved performance. | It has a limited range (excluding 802.11ac) but works well in smaller spaces. |
| 5 GHz | Other signals cause less disruption. | Struggles to pass through walls. |
| 5 GHz | It has fewer devices connected to it. |
2.4 GHz vs. 5 GHz: Which one is right for you?
The 2.4 GHz band covers a larger area but offers slower speeds. On the other hand, 5 GHz delivers faster speeds but works over shorter distances. Your choice depends on how and where you use your WiFi.
Many devices, like microwaves, baby monitors, security cameras, and garage door openers, operate on the 2.4 GHz frequency.
If you have several of these or live in an apartment or condo, the 2.4 GHz band might be crowded, affecting speed and signal quality.
Use 5 GHz for devices near the router
Choose 5 GHz when your device stays close to the router. This frequency offers faster speeds, which is ideal for gaming or videoconferencing.
Stay near the router to get the best performance. For an even better connection, use an Ethernet cable.
Wired connections are faster and more reliable than wireless. If you live in an apartment or condo with many nearby networks, 5 GHz reduces interference.
Use 2.4 GHz for devices farther from the router.
Pick 2.4 GHz for devices used far from the router. This frequency has a broader range and works better through walls. It is suitable for smartphones, or devices moved between rooms in large homes.
Newer routers with 5 GHz 802.11ac WiFi can sometimes match the 2.4 GHz range in certain conditions.
How to adjust frequency settings?
Enable your router’s wireless feature and match the chosen frequency. Check your router’s model to confirm its frequency capabilities.
If your router supports dual-band, set it to broadcast both 2.4 GHz and 5 GHz. Two networks will appear in your list, labeled “2.4G” or “5G.” Connect devices to the preferred network.
Most modern routers let you optimize WiFi channels. Adjust the channel in the settings to improve performance for your chosen frequency.
