In this article, we’ll dive deep into the world of WiFi frequencies, explore the differences between 2.4GHz and 5GHz, and investigate whether disabling 5GHz can indeed boost your WiFi range.
Understanding WiFi Frequencies: The Basics
Before we dive into the topic, it’s essential to understand the basics of WiFi frequencies. WiFi signals operate on two primary frequencies: 2.4GHz and 5GHz. Both frequencies have their strengths and weaknesses, which we’ll explore in detail.
2.4GHz Frequency
The 2.4GHz frequency is the older and more established of the two. It’s widely used and supported by most devices, including older laptops, smartphones, and routers. The 2.4GHz frequency has a longer wavelength, which allows it to penetrate solid objects like walls and furniture more easily. This makes it a better option for larger spaces or areas with many obstacles.
However, the 2.4GHz frequency is also more prone to interference from other devices, such as microwaves, cordless phones, and neighbors’ WiFi networks. This can lead to slower speeds and dropped connections.
5GHz Frequency
The 5GHz frequency is a more recent introduction to the WiFi landscape. It’s a shorter wavelength frequency that offers faster speeds and lower latency compared to 2.4GHz. The 5GHz frequency is better suited for devices that require high-bandwidth applications, such as online gaming, 4K video streaming, and heavy file transfers.
However, the 5GHz frequency has a shorter range and is more affected by physical barriers like walls and furniture. This means that 5GHz signals may not be as strong or consistent in larger spaces or areas with many obstacles.
The Impact of 5GHz on WiFi Range
Now that we’ve covered the basics of WiFi frequencies, let’s explore how 5GHz affects WiFi range.
Limited Range and Interference
As mentioned earlier, the 5GHz frequency has a shorter range compared to 2.4GHz. This means that devices operating on the 5GHz frequency may experience a weaker signal and reduced range. Additionally, the 5GHz frequency is more prone to interference from other devices, which can further reduce its range and stability.
In a crowded WiFi environment, the 5GHz frequency can be more prone to congestion and interference, leading to reduced WiFi range.
5GHz Channel Overcrowding
The 5GHz frequency operates on a smaller number of channels compared to 2.4GHz. This can lead to channel overcrowding, where multiple devices are competing for the same limited number of channels. This increased competition can result in slower speeds, dropped connections, and reduced WiFi range.
5GHz Device Compatibility
Not all devices support the 5GHz frequency. Older devices, in particular, may only operate on the 2.4GHz frequency. This means that if you have a large number of devices connected to your network, turning off the 5GHz frequency may not have a significant impact on your WiFi range.

Additionally, using range-extending devices or access points can help amplify the signal and provide a stronger connection around obstacles.
How does network congestion affect WiFi range?
Network congestion can significantly affect WiFi range, as a large number of devices competing for bandwidth can cause the signal to degrade. When multiple devices are connected to the network, they can cause congestion, resulting in slower speeds and a weaker signal. This can be particularly problematic in households with many devices, such as smart home devices, gaming consoles, and streaming devices.
To minimize the impact of network congestion, it’s essential to optimize the network configuration, limit the number of devices connected to the network, and use Quality of Service (QoS) settings to prioritize traffic. Additionally, upgrading the router’s firmware and using a router with a strong processor can help improve the network’s ability to handle a large number of devices.
Can using a WiFi range extender improve WiFi range?
Using a WiFi range extender can improve WiFi range, but its effectiveness depends on the type and quality of the extender, as well as the environment it’s operating in. A WiFi range extender can amplify the signal, providing a stronger connection to areas with weak or no signal. However, the extender can also introduce latency and reduce the overall speed of the network.
To get the most out of a WiFi range extender, it’s essential to position it in a location that provides a strong signal, use a high-quality extender that supports the same frequency band as the router, and optimize the extender’s settings to minimize interference and latency.
Are there any other ways to improve WiFi range besides turning off 5GHz?
Yes, there are several other ways to improve WiFi range besides turning off the 5GHz frequency. These include positioning the router in a central location, using range-extending devices or access points, upgrading the router’s firmware, optimizing the network configuration, limiting network congestion, and using Quality of Service (QoS) settings to prioritize traffic. Additionally, using a mesh network system, which uses multiple access points to provide a strong and reliable signal throughout the coverage area, can also improve WiFi range.
It’s essential to identify and address the underlying causes of poor WiFi range, such as physical barriers, interference from other devices, and network congestion, to achieve the best possible coverage and performance. By using a combination of these strategies, it’s possible to improve WiFi range and provide a strong and reliable connection to all devices on the network.
