Here, we are not going to talk about packet sniffing attacks, but some free packet sniffing tools that can be effectively used to diagnose network problems and resolve the issues. Before we present you three packet sniffing tools for Windows, let’s look at how packet sniffing tools work in general.
How Packet Sniffing tools work
There are different types of packet sniffers. Some packet sniffers are used only for detecting hardware-related problems. Other packet sniffing tools are actually some software apps that run on the host computers. The packet sniffing tools intercept and log network traffic. The tools ‘view’ the network using a wireless or wired network interface. The packet sniffing tool needs to have access to this interface on its host computer. If it is a wired network, a packet sniffing tool can capture the data which totally depends on the network’s structure. The network structure might let the packet sniffer tool view traffic on the entire network or it can let it view only a small segment of it. If it’s a wireless network, packet sniffing tools can capture one channel using the wireless interface. If the host computer has multiple wireless interfaces, then the packet sniffer can capture multiple channels. The sniffing tool then analyzes the captured raw packet data. The analysis is converted by the sniffing tool into a readable format. This analysis is nothing but the conversation between nodes on the network. This very information is helpful for the network technicians to locate the fault.

Free Packet Sniffing Tools for Windows 11/10
If you also wish to analyze your network, here are three free packet sniffing tools for Windows.
1. WireShark Packet Sniffer
Wireshark is one of the popular free packet sniffing tools for Windows. This tool can give you an ability to see what’s happening on your network at a microscopic level. Some of the important features of this tool are as follows:
Deep inspection of hundreds of protocols, with more being added all the timeLive capture and offline analysisStandard three-pane packet browserApart from Windows, this tool can run on other operating systems such as Linux, OS X, Solaris, FreeBSD, NetBSD, and many othersCaptured network data can be browsed via a GUI, or via the TTY-mode TShark utilityThe most powerful display filters in the industryRich VoIP analysisDecryption support for many protocols, including IPsec, ISAKMP, Kerberos, SNMPv3, SSL/TLS, WEP, and WPA/WPA2Coloring rules can be applied to the packet list for quick, intuitive analysisOutput can be exported to XML, PostScript®, CSV, or plain text
You can try this tool by downloading it from its website.
2. SmartSniff
SmartSniff is yet another free packet sniffing tool that allows you to capture TCP/IP packets that pass through your network adapter and view the captured data as sequence of conversations between clients and servers. With the help of this network monitoring utility, you can view the TCP/IP conversations in ASCII mode or as hex dump. SmartSniff provides 3 methods for capturing TCP/IP packets: If you wish to try this packet sniffing tool, download it from here.
3. Microsoft Message Analyzer
Microsoft Message Analyzer is the successor to Microsoft Network Monitor. It is helpful in capturing, displaying, and analyzing protocol messaging traffic and other system messages. It is not only an effective tool for troubleshooting network issues, but for testing and verifying protocol implementations as well. Do let us know if you have any other free packet sniffing tools to add. You might want to also check out some of these free Network Monitoring Tools.
