![]() Fortunately, many wireless cards support the ability to capture wireless traffic without needing to connect to a network with the monitor mode feature.īy leveraging available tools and drivers for Windows and Linux systems, you can use a standard wireless card (Alfa card) to capture traffic on the wireless network for analysis. Packet sniffing on wireless networks has unique challenges that are different than the challenges of capturing traffic on wired networks. In our case, wla0mon is the new interface name. Step 2 – Put your wireless card into monitor mode by typing “ airmon-ng start wlan0” command. Most wireless drivers for Linux systems use the Linux Wireless Extensions interface, providing a consistent configuration interface for manipulating the wireless card. In our case, wlan0 is the name of our wireless interface. To check your wireless interface name, type “ iwconfig” command as shown below. Step 1 – Make sure that your wireless card must be in working condition and must supports promiscuous mode and packet injection. When you switch to wireless analysis, however, the process of traffic sniffing becomes more complicated and requires additional decisions up front to best support the analysis you want to perform. In both of these cases, it is easy to initiate a packet capture and start collecting traffic for analysis.
