Wireshark is a free tool that should be part of every networking professional’s arsenal. While it can be a rather intimidating and cumbersome tool, it allows for inspection of packets in their dissected form.
The beauty of that is packets never lie. When you’re experiencing networking issues or just need to know what’s going on in your network you can trust the data from Wireshark.
Wireshark is potentially one of the best packet analyzer tools available today.
Fortunately, downloading and installing Wireshark is super simple.
How to Download Wireshark for Windows 10 (or Windows Server 2019)
- Head over to https://www.wireshark.org/download.html and click on the appropriate installer for your operating system (Windows 10 64-bit in this example).
- Note that a Wireshark-win64-2.6.1.exe file (file name as of July 2018) will be saved to your default downloads location.
How to Install Wireshark for Windows 10 (or Windows Server 2019)
- Run the exe installer that was downloaded.
- Click Next on the Welcome to Wireshark screen.
- Read the license agreement and click I Agree.
- At the Choose Components screen leave the defaults checked and click Next. You can read more about the different components here.
- At the Select Additional Tasks screen choose your preferred shortcuts and leave the radio button for “associate trace file extensions to Wireshark” selected. Click Next.
- Choose the install location you prefer and click Next.
- At the Packet Capture page make sure Install WinPcap 4.1.3 is selected. You need this to capture traffic with Wireshark. Without it you can still view Wireshark capture files. Click Next.
- At the USB Capture page you can choose to Install USBPcap. Check the box next to Install USBPcap 22.214.171.124 if you desire to capture raw usb traffic as well (such as from a USB to RJ45 Ethernet adapter). Click Install.
- The software will begin installing.
- Eventually the installer will pause at “Execute: “C:\Program Files\Wiresharek\WinPcap_4_1_3.exe” and lunch a new installer window for WinPcap. Click Next in this window.
- Read the license agreement and click I Agree.
- Make sure the check box is checked next to “Automatically start the WinPcap driver at boot time” unless you have a good reason for disabling this and click Install.
- The install will begin and eventually complete. Click Finish.
- Next the installer for USBPcap will launch. Read the USBPcap Driver license agreement, check the “I accept” box, and click Next.
- Read the USBPcapCMD license, check the “I accept” box, and click Next.
- Leave the Installation Options set to Full and click Next.
- Choose your Installation Folder and click Install. The install will begin.
- When the USBpcap install finishes click close and the Wireshark install will continue.
- At the Installation Complete screen click Next.
- Wireshark will now ask to reboot your machine to complete installation. You can either choose to reboot now or manually reboot later. You will not be able to run packet captures until you reboot your machine. I suggest rebooting right away.
Once your machine has rebooted you should find the Wireshark shortcuts in the locations you specified in the install. For this example the shortcut was found in the Start Menu.
