In this blog post, we’ll explain what is frequency in WiFi and explore its impact on your internet connection. We’ll discuss the differences between the primary WiFi frequency bands and the advantages of dual-band and tri-band routers. 

By understanding the ins and outs of WiFi frequency, you can make informed decisions about your home network setup and ultimately improve your time online. So, let’s discover WiFi frequency bands and their characteristics! 

Understanding WiFi Frequency Bands

So, what is the frequency in WiFi? To put it simply, WiFi frequency refers to the specific range of radio waves that your wireless network uses to transmit data between devices. WiFi technology has two primary frequency bands: the 2.4 GHz and 5 GHz bands.  

These two bands, also known as WiFi bands, have unique characteristics that can affect your internet range, speed, and susceptibility to interference. Understanding the differences between these two WiFi frequency bands is essential for optimizing your wireless network and getting the most out of your internet connection.  


Exploring the 2.4 GHz WiFi Band

The 2.4 GHz frequency band is one of the two main WiFi bands and has been the backbone of wireless communication for many years. Its characteristics make it suitable for various internet activities, but it’s essential to understand its advantages and limitations.  

Despite its limitations, the 2.4 GHz WiFi frequency band remains a popular choice for everyday internet usage. It’s worth noting that some older devices may only support this band, so it’s essential to consider compatibility when setting up your wireless network. 

Below, we explore the key features of the 2.4 GHz WiFi frequency band, namely range, speed, and interference. 


One of the main advantages of the 2.4 GHz frequency band is its range. The 2.4 GHz signals can travel longer distances compared to the 5 GHz signals, making it ideal for covering larger areas. This is especially beneficial for those who need their WiFi network to reach multiple rooms or even outdoor spaces. 


Regarding speed, the 2.4 GHz band is typically slower than the 5 GHz band. While it can still provide a decent internet connection, it’s not the best choice for high-bandwidth activities like online gaming or video streaming. However, it’s still perfectly suitable for basic tasks like browsing the web or checking emails. 


One of the main drawbacks of the 2.4 GHz band is that it’s more susceptible to interference. Since many household devices like microwaves, cordless phones, and Bluetooth speakers operate on the same frequency, the 2.4 GHz band can become crowded. This can lead to slower speeds and connection issues. 

The Benefits of the 5 GHz WiFi Band

Now that we’ve covered the 2.4 GHz WiFi frequency band, let’s move on to its counterpart, the 5 GHz frequency band. This band is gaining popularity among users who need faster internet speeds and a more stable connection. Below, you can see how it compares to the 2.4 GHz band.  


While the 5 GHz band doesn’t have the same extensive range as the 2.4 GHz band, it can still provide adequate coverage, especially in smaller spaces or when the router is centrally located. Think of the 5 GHz band like a sprinter – it covers less distance, but it does so at a faster pace. 


One of the most significant advantages of the 5 GHz band is its speed. With higher data transfer rates, the 5 GHz frequency band is perfect for high-bandwidth activities, such as streaming high-definition videos, online gaming, and video conferencing.  


Another benefit of the 5 GHz band is its reduced susceptibility to interference. Since fewer devices operate on this frequency, there’s less congestion, resulting in a more stable and reliable connection. 

In a nutshell, the 5 GHz WiFi frequency band offers faster speeds and reduced interference compared to the 2.4 GHz band, albeit with a slightly shorter range. Understanding the differences between the two bands can help you make informed decisions about your network setup and optimize your internet experience.

Switching Between Frequencies & Checking Your Current Frequency

Switching between WiFi frequencies and checking your current frequency is a relatively simple process. Knowing how to make these adjustments can help you optimize your internet connection based on your specific needs.  

Here’s a step-by-step guide on how to switch between WiFi frequencies and check your current frequency: 

  • Check your router’s capabilities: Before attempting to switch frequencies, ensure your router supports both the 2.4 GHz and 5 GHz bands. You can typically find this information in your router’s user manual or on the manufacturer’s website. 
  • Access your router’s settings: To switch between WiFi frequencies or check your current frequency, you’ll need to access your router’s settings. This usually involves opening a web browser and entering your router’s IP address ( or into the address bar. You can find the specific IP address for your router in its user manual or by searching for it online. 
  • Log in to your router’s settings: Once you’ve accessed your router’s settings, you’ll be prompted to enter your username and password. If you haven’t changed these from the default settings, you can find them in your router’s user manual or on a sticker attached to the router itself. 
  • Navigate to the wireless settings: In your router’s settings, locate the wireless or WiFi settings section. This is where you’ll find options to configure your WiFi network’s frequency bands. 
  • Check your current frequency: Under the wireless settings, you should see information about your current WiFi network, including the frequency band in use (either 2.4 GHz or 5 GHz). This will help you determine which frequency you’re currently on. 
  • Switch between frequencies: To switch between the 2.4 GHz and 5 GHz bands, you’ll need to adjust your router’s wireless settings. This can involve enabling or disabling a specific frequency band or creating separate network names (SSIDs) for each band. Once you’ve made the necessary changes, save your settings and restart your router. 
  • Connect your devices: After setting up your preferred frequency bands, reconnect your devices to the appropriate WiFi network.  

By following these steps, you can easily switch between WiFi frequencies and check your current frequency to optimize your internet connection.  

Dual-Band and Tri-Band Routers

Before you start changing WiFi frequencies, it’s important to note that most modern routers are now dual-band or tri-band. That means they can work on both the 2.4 GHz and 5 GHz bands simultaneously. 

With these routers, you can enjoy the benefits of each frequency band without manually switching frequencies. Let’s explore the advantages of dual-band and tri-band routers and how they can help optimize your internet experience. 

Dual-Band Routers 

These routers support both the 2.4 GHz and 5 GHz frequency bands. By offering both bands, dual-band routers enable you to assign devices to the most suitable frequency, depending on their requirements. 

For example, you can connect low-bandwidth devices like smart thermostats or basic web browsing to the 2.4 GHz band, while reserving the 5 GHz band for high-bandwidth activities like gaming or streaming. 

Tri-Band Routers 

These advanced routers take it a step further by offering not just two but three frequency bands – one 2.4 GHz band and two separate 5 GHz bands. Tri-band routers are perfect for households or offices with numerous devices and heavy internet usage.  

By having an additional 5 GHz band, these routers can handle even more devices simultaneously, reducing congestion and maintaining optimal performance across your network.
