In the modern era, we depend on the internet for almost everything. Due to the increase in the transactions, network issues can be a real problem. There are often cases when we face problems related to network issues, but sometimes, the problem isn’t just a technical error. It could be someone spying on your network activity. This is called network sniffing.
Learn about why Wireshark is the top choice for network traffic analysis and install Wireshark in minutes with this step-by-step guide.
What is Wireshark?
Wireshark is an open-source tool for analyzing network traffic on Windows, macOS, UNIX, and Linux. It captures data packets that pass through a network interface like Ethernet, Wi-Fi (LAN), or SDRs and converts that raw data into readable information that IT and security teams can use.
Wireshark is a type of packet sniffer (also called a network protocol analyzer or network analyzer). Packet sniffers intercept network traffic so you can see what’s happening on the network and extract useful insights.

Once you’ve selected the installation location, click “Next” to continue.
Step 5: Install the Npcap Packet Capture Driver
Wireshark requires a packet capture driver to function properly, and the installer will prompt you to install the Npcap driver. Npcap is a powerful packet capture library that provides enhanced functionality and compatibility with modern Windows systems.
It’s recommended to select the “Install Npcap and WinPcap API-compatible mode” option, as this will ensure that Wireshark can capture and analyze network traffic, including wireless traffic, effectively.
Once you’ve made your selection, click “Install” to begin the installation process. This may take a few minutes, so be patient while the installer completes the necessary tasks.
Step 6: Complete the Installation
After the Npcap driver installation is complete, the Wireshark installer will prompt you to select additional options, such as creating desktop shortcuts and associating trace file extensions with Wireshark.
Make your selections based on your preferences and click “Next” to continue. Finally, the installer will display a confirmation screen, indicating that Wireshark has been successfully installed on your Windows computer. Click “Finish” to close the Setup Wizard.
