How to Determine if Your Network Is 2.4 GHz or 5 GHz


Are you wondering what frequency band your Wi-Fi network is operating at? Understanding whether your network is using the 2.4 GHz or 5 GHz frequency can be helpful, especially when it comes to optimizing your network’s performance. In this tutorial, we will guide you through the process of checking and determining the frequency band of your network. By the end, you’ll have a clear understanding of whether your network is operating at 2.4 GHz or 5 GHz.

Why It Matters

Different Wi-Fi frequency bands have distinct characteristics and advantages. The 2.4 GHz band has a wider signal range but is more prone to interference from other devices such as microwaves, cordless phones, and neighboring Wi-Fi networks. On the other hand, the 5 GHz band offers faster data transfer speeds and is generally less crowded, resulting in a more stable and reliable connection. Knowing which frequency band your network is using will help you troubleshoot connectivity issues and optimize your Wi-Fi experience.

Using Your Device’s Network Settings

The easiest way to determine whether your network is operating at 2.4 GHz or 5 GHz is to check your device’s network settings. The process may vary slightly depending on the operating system you’re using, but here’s a general guide:

  1. On Windows:
    • Right-click on the network icon in the taskbar.
    • Select “Open Network & Internet settings.”
    • Click on “Wi-Fi” on the left sidebar.
    • Under the “Network profile” section, you’ll find the frequency band mentioned (e.g., 2.4 GHz or 5 GHz).
  2. On macOS:
    • Click on the Wi-Fi icon in the menu bar.
    • Select “Open Network Preferences.”
    • Click on “Advanced” in the bottom right corner.
    • In the Wi-Fi tab, you’ll see the network name followed by the frequency band (e.g., “Network Name – 5 GHz”).
  3. On Android:
    • Open the “Settings” app.
    • Tap on “Wi-Fi & Internet” or “Connections,” depending on your device.
    • Select “Wi-Fi.”
    • Look for the connected network and tap on it.
    • You’ll find the frequency band mentioned under the network name (e.g., 2.4 GHz or 5 GHz).
  4. On iOS:
    • Open the “Settings” app.
    • Tap on “Wi-Fi.”
    • Find the connected network and tap on the information (i) icon next to it.
    • The frequency band (2.4 GHz or 5 GHz) will be mentioned under “Frequency.”

Using Network Analyzer Apps

If you prefer a more detailed analysis of your Wi-Fi network, you can use network analyzer apps available for both smartphones and desktops. These apps provide comprehensive information about your network, including the frequency band. Popular network analyzer apps include NetSpot (for Windows and macOS) and Network Analyzer (for Android and iOS).

Using such an app typically involves installing it, scanning your network, and accessing the details of your network connection. Within the details, you’ll find the frequency band listed. These apps are particularly useful for troubleshooting connectivity issues, identifying channels with less interference, and optimizing your network for better performance.

Checking Router Settings

Another method to determine the frequency band of your network involves accessing your router’s settings. Here’s a general guide for checking your router settings:

  1. Open a web browser on a connected device.
  2. Type your router’s IP address into the address bar (common addresses include or
  3. Enter your router’s username and password (usually provided on the router or in the documentation).
  4. Look for a section named “Wireless,” “Wi-Fi Settings,” or similar.
  5. Under this section, you should find information about your network, including the frequency band (2.4 GHz or 5 GHz).

Keep in mind that router interfaces can vary, so the exact steps and terminology may differ between different router models. Consulting your router’s user manual or visiting the manufacturer’s support website can provide specific guidance for your device.

Online Tools for Network Analysis

In addition to network analyzer apps, you can also leverage online tools to determine the frequency band of your network. These tools work by scanning your Wi-Fi network remotely and providing you with detailed information, including the frequency band.

One popular online tool is the “WiFi Signal Analyzer” provided by Simply visit their website, click on the “Change Server” option, and select a server near your location. The tool will then scan your network and display various details, including the frequency band.

Another great online tool for network analysis is the “WiFi Analyzer” provided by This tool allows you to enter your network’s information manually or take an automated network photo using your smartphone. The results will include key details about your network, including the frequency band it is operating on.

By utilizing these online tools, you can obtain accurate information about your network’s frequency band without the need to install any additional applications on your devices.

Using Wireless Network Adapters

If you are still unsure about the frequency band of your network, another option is to check the specifications of your wireless network adapter. Whether it’s a USB dongle or an internal card, the adapter specifications will provide clarity on whether it supports the 2.4 GHz band, 5 GHz band, or both.

To find these specifications, you can check the product documentation that came with your adapter or visit the manufacturer’s website for detailed information. Look for details specifically mentioning the frequency or “dual-band,” which means the adapter supports both 2.4 GHz and 5 GHz bands.

Knowing which frequency bands your wireless network adapter supports will give you a good indication of the frequency band your network is utilizing. It is worth noting that even if your adapter supports both bands, your network may still be operating on one specific frequency. Checking the network settings using the methods mentioned earlier will confirm the actual frequency band being used.

Dual-Band Routers and Compatibility

Many modern routers are capable of utilizing both the 2.4 GHz and 5 GHz bands simultaneously. These routers, known as dual-band routers, allow you to connect devices to either frequency band based on their capabilities and requirements.

While dual-band routers offer flexibility and improved performance, it is essential to ensure that your devices are compatible with the desired frequency band. Older devices may only support the 2.4 GHz band, so connecting them to a 5 GHz network won’t be possible.

To maximize compatibility and take advantage of the benefits of both frequency bands, consider connecting devices that support the 5 GHz band to that network. This will free up the 2.4 GHz band and reduce congestion for devices that are limited to 2.4 GHz connectivity.


Determining the frequency band of your Wi-Fi network is crucial for optimizing your network’s performance and addressing connectivity issues. Whether you use your device’s network settings, network analyzer apps, online tools, or check adapter specifications, you now have multiple methods to identify whether your network operates on the 2.4 GHz or 5 GHz band.

Being able to distinguish between the frequency bands allows you to make informed decisions regarding device compatibility, channel selection, and Wi-Fi optimization. Understanding the frequency band will enable you to enhance your Wi-Fi experience and ensure a stable and fast wireless network connection for all your devices.
