Input the IP address to the address bar in the web browser and you will visit the GUI of the SMB router.Īfter logging into the page, go to Network-Switch-Mirror, enable Port Mirror, select the port connecting to your PC in the Mirroring Port and the port you want to capture packets in the Mirrored Port, click Save. Set Port Mirror for PC and the port you want to capture packets.Connect PC to the SMB router or switch directly.Download and install Wireshark on your PC.

Note: Connect PC to SMB router or switch directly. It’s a free and powerful sniffing and analyzing software. This document will introduce how to capture packets using Wireshark in SMB router or switch. If you want to avoid any costs associated with drivers for monitor mode packet capture, you are encouraged to use a Linux option.Packets capture and analysis are very important for us to troubleshoot when some problems occur such as the router can’t obtain IP from ISP, the client can’t receive multicast packets, etc. If you need to perform wireless traffic analysis with a Windows workstation, Wireshark is an effective tool however, you would have to purchase a driver and hardware combination that supports monitor mode. Unfortunately, at the time of this writing, there are no free software solutions that allow Windows users to capture wireless traffic reliably, and without violating other software license restrictions. Ensure you have installed the appropriate version (WinPcap 4.0 beta 1) of WinPcap to support the AirPcap. AirPcap is available at After obtaining the AirPcap CD and USB wireless adapter, follow the installation instructions detailed in the AirPcap User s Guide. A combination of a USB IEEE 802.11b/g adapter, supporting driver software, and a client configuration utility, AirPcap provides a simple mechanism to capture wireless traffic in monitor mode on Windows workstations at a reasonable cost. In order to overcome the limitations with most wireless drivers for Windows systems, the engineers at CACE Technologies have introduced a commercial product called AirPcap.
