Generally, a home user never monitors Wi-Fi connections until an issue arises. Keeping an eye on Wi-Fi connections helps you in resolving three different things. Firstly, you can optimize these connections using the best possible settings to get the best network speed. Secondly, you can check for unauthorized access to your Wi-Fi network. And lastly, it can be used to troubleshoot any Wi-Fi network issues. In this easy-to-follow guide, we'll discuss some of the best and easiest ways to monitor Wi-Fi connections on both Windows and Linux platforms. Some of these monitoring tools are available for Mac as well.
Even if you're not sharing your Wi-Fi network with anyone, monitoring it is highly recommended to ensure the safety and security of devices using that network. Bandwidth stealing is also an issue.
Both GUI and command line tools are mentioned in this guide. Feel free to choose the one you feel comfortable with. For technically sound users, advanced tools like Wireshark are discussed too.
Why Monitor Wi-Fi Networks?
Before we move ahead discussing various ways to monitor a Wi-Fi network, let's get familiar with the advantages of the same. Here are some of the reasons one should diligently monitor Wi-Fi networks.
- Performance Improvement: Monitoring activity helps in checking the signal strength of a Wi-Fi network. You can address this issue by placing the router in the right place or by removing obstructions—if any. This helps in better performance of the network by giving you improved speed and connectivity.
- Network Security: Monitoring also helps in identifying unauthorized connections and unusual data consumption statistics. This way, you can easily identify both intruders as well as unfair bandwidth usage by a specific user.
- Network Troubleshooting: Last but not least, regular monitoring aids in troubleshooting network issues. Data associated with monitoring can easily help you pinpoint the reason for an issue.
Wi-Fi Monitoring on Windows
Let's get started with Wi-Fi monitoring options available for the Windows platform. Fortunately, there are several tools for the same. Some of these tools are basic while others are advanced with lots of options. Depending on your preference or the specific need, you can select or switch between these tools.
Built-in Tools on Windows
Let's see some of the built-in tools that can be used to monitor Wi-Fi networks on Windows. Here's the first one.
Task Manager: One of the simplest ways to check Wi-Fi connection details is the Windows Task Manager. It's easy to access and tabulates a lot of data.
You can access it quickly using the Ctrl + Shift + Esc keyboard shortcut. The data associated with the Wi-Fi connection is on the Performance tab. At a glance, you can see the IP address, the network's SSID, signal strength, and data flow speed. In a nutshell, it's a good option to get the basic details of a Wi-Fi connection.
Command Prompt Utilities: To get more details about available Wi-Fi connections, one can use some of the built-in tools that work in the command line environment.
The first one is the netsh command. To use it, first open the command prompt with administrator privileges. Then use the following command.
netsh WLAN show allIt shows tons of advanced data about all the available WI-Fi connections. It can be used by power users to identify and troubleshoot Wi-Fi connection issues.
One can also use the ping command to check the connection's reliability and stability.
ping netflix.comAlthough it's a basic utility—at times—it is the best one to quickly check the stability of the network connection. Once the ping exhibits connection instability, you can switch to a more advanced tool to gather more information about your Wi-Fi connection.
Third-Party Tools on Windows
Till now, we've discussed the built-in tools in Windows to monitor Wi-Fi connections. Let's see some of the 3rd-party tools for the same.

- This tool is for advanced users who are technically sound. You can use it for troubleshooting Wi-Fi network issues.
- Acrylic Wi-Fi
- Unlike Wireshark, this tool can be used even by a layman. Its user-friendly UI gives you all the data to quickly analyze available Wi-Fi connections.
- It's one of the best options to analyze the signal strength of Wi-Fi connections. This helps you in choosing the best available network.
- You can use it to monitor Wi-Fi networks in real-time. Advanced users can export monitoring data to analyze the connections in detail.
- NetSpot
- Network administrators generally use it for planning and visualization of large Wi-Fi networks. But, a general home user can use it to monitor these networks in real-time.
- Through heat maps and extensive performance reports, you can easily identify the bottlenecks in your Wi-Fi network.
- One can also use it to boost the Wi-Fi signals to eliminate dead zones in your home network.
Windows PowerShell Commands
There's another powerful tool Windows has on offer to analyze Wi-Fi network data. It's easy to use and gives you ample information about wireless networks. Here's the first command.
Get-NetAdapterStatisticsYou can use this command to see network Wi-Fi network adaptor statistics which include sent and received bytes.
Get-NetIPAddressSimilarly, the command shown above can give you detailed information about all the network adaptors including their IP addresses.
Wi-Fi Monitoring on Linux
If you're on Linux, the number of tools is far more than on Windows. And, if you're a command line geek, the available tools are both powerful and extremely flexible.
Command-Line Tools on Linux
- iwconfig
- The
iwconfigcommand is easy to use and gives you ample information about available networks. Here's how you can use it.
iwconfig wlan0 - The
- This command can be used to display frequency, bitrate, and the signal strength of the wireless network.
- iwlist
- Another excellent tool to scan all the available Wi-Fi networks is the
iwlistcommand. Here's an example of the same.
sudo iwlist wlan0 scan - Another excellent tool to scan all the available Wi-Fi networks is the
- This command will not only display the list of available Wi-Fi connections, but also the SSIDs, their signal levels, and the encryption status of each network.
- ping
- The
pingcommand is available on both Windows and Linux. The usage is identical.
ping netflix.com - The
- It's a handy tool to check connection stability by checking how many packets are lost during a data transfer.
