An unstable and unreliable internet connection can easily frustrate and ruin your day. Whether you are streaming videos, playing games, or just browsing the internet, having a good WiFi connection is essential.

However, choosing the right WiFi band is not as simple as it seems. With two popular bands – 2.4GHz and 5GHz – available, it can be confusing to determine which one is better. In this article, we will explore the differences between these two bands including their pros and cons so you can choose the best one for your needs. But first, let’s take a quick look at the basics.

The Basics of WiFi Bands

A WiFi band is a radio frequency that your device uses to communicate with your router. There are two main WiFi bands – 2.4GHz and 5GHz. The difference between these two bands lies in their frequency range.

Understanding the Differences Between 2.4GHz and 5GHz

When it comes to choosing between 2.4GHz and 5GHz, there are several factors to consider. These include range, speed, interference, device compatibility, and security.


One of the most significant differences between 2.4GHz and 5GHz is their range. 2.4GHz has a more extended range than 5GHz. It can penetrate walls and other obstacles more effectively, making it a better option for larger spaces. On the other hand, 5GHz has a shorter range but is less prone to interference.


When it comes to speed, 5GHz is faster than 2.4GHz. This is because 5GHz has a wider channel width, allowing more data to be transmitted at once. This makes 5GHz the better option for activities that require a lot of bandwidth, such as streaming videos and online gaming.


Interference can also affect your WiFi performance. 2.4GHz is more prone to interference from other devices that operate on the same frequency range, such as microwaves, Bluetooth devices, and cordless phones. In contrast, 5GHz operates on a less crowded frequency range and is less prone to interference.

Device Compatibility

When choosing between 2.4GHz and 5GHz, it is essential to consider device compatibility. Older devices may only support 2.4GHz, while newer devices may support both 2.4GHz and 5GHz. If you have a lot of older devices, 2.4GHz may be a better option for you. However, if you have newer devices, 5GHz may be a better option for faster speeds.


Finally, security is another factor to consider when choosing between 2.4GHz and 5GHz. While both bands support various security protocols, such as WEP, WPA, and WPA2, 5GHz is generally considered to be more secure. This is because 5GHz has a shorter range and is less prone to interference, making it harder for unauthorised users to access your network.

Pros and Cons of 2.4GHz


  • Longer range: 2.4GHz has a longer range than 5GHz, making it ideal for use in larger spaces or for outdoor use.
  • More devices supported: Because it has been around for longer, more devices support 2.4GHz, including older devices that may not support 5GHz.
  • Better penetration: 2.4GHz has better penetration through walls and other obstacles, making it more reliable in some situations.


  • Slower speed: 2.4GHz has a slower maximum speed than 5GHz, meaning that data transfer may be slower.
  • More susceptible to interference: 2.4GHz is more susceptible to interference from other wireless devices such as microwaves, cordless phones, and other routers, which can cause slow speeds or dropped connections.
  • Congestion: Because it is more widely used, 2.4GHz is more prone to congestion, especially in urban areas where many networks may be present.

Pros and Cons of 5GHz


  • Faster speed: 5GHz has a faster maximum speed than 2.4GHz, making it ideal for tasks that require high-speed data transfer, such as streaming video or gaming.
  • Less susceptible to interference: 5GHz is less susceptible to interference from other wireless devices, making it more reliable in areas where there may be many other networks present.
  • More channels available: There are more channels available for use in the 5GHz band, reducing congestion and allowing for more devices to be connected simultaneously.


  • Shorter range: 5GHz has a shorter range than 2.4GHz, making it less suitable for larger spaces or outdoor use.
  • Less device compatibility: Because it is a newer technology, some older devices may not support 5GHz.
  • Higher power consumption: 5GHz requires more power to transmit signals, which can result in decreased battery life on mobile devices.


Overall, the choice between 2.4GHz and 5GHz depends on your specific needs. If you require longer range and support for older devices, 2.4GHz may be the way to go. However, if you require faster speeds and less interference, 5GHz may be the better option. It’s important to consider all of these factors before making a decision. Router technology is changing fast with a new 6GHz band just released in New Zealand by the Government. Although most Wifi devices are not yet compatible with the new band, it’s just a matter of time. This new band will offer less coverage but much greater speeds due to the increased frequencies available.

Note: Most modern dual band routers that support both bands will automatically detect your devices radio signals and choose which band is best for your connection making the frequency change within 2.4GHz and 5Ghz automatic.
