Get SNR Values in Wireless Network - Windows 11

In this article, we'll cover how to get Signal-to-Noise Ratio (SNR) values for your wireless network connections on a Windows 11 system. SNR is a crucial metric that determines the quality of your wireless signal.

What is SNR?

Signal-to-Noise Ratio (SNR) is the difference between the signal strength and the background noise measured in decibels (dB). A higher SNR value indicates better wireless signal quality. To learn more about SNR, you can refer to the following resources:

Using WSL (Ubuntu) to Get SNR Values

While WSL (Windows Subsystem for Linux) and tools like iw and wavemon can work for getting SNR values on Linux systems, they don't directly work with Windows 11 Network Interface Cards (NICs). If you encounter an error like nl80211 not found, it's because these tools are not compatible with Windows NICs.

Third-Party Applications

You can use third-party applications like NetSpot to get SNR values on Windows 11. NetSpot is a popular tool for wireless site surveys and troubleshooting. You can download it from their official website. Here's how to get SNR values using NetSpot:

Download and install NetSpot.
Launch NetSpot and select Discover mode.
Choose your Wi-Fi network from the list, and NetSpot will display the SNR value along with other network information.

Command-Line Tools

In Windows 11, you can use PowerShell or Command Prompt to get wireless network information. However, the SNR value is not directly provided. You can use a workaround by using the following steps:

Open PowerShell or Command Prompt and run the following command:


 netsh wlan show interfaces

Parse the output for the Signal and Noise values.
Manually calculate the SNR value by subtracting the Noise value from the Signal value.

While it's not straightforward to get SNR values for a wireless network in Windows 11 using built-in tools, you can use third-party applications like NetSpot or parse the output of netsh wlan show interfaces command to manually calculate the SNR value.
