In wireless protocol, there are two radio frequency bands: Here is the screenshot to explain all the above steps: So, make interface down using the following command.įinally, check whether the interface is in monitor mode using the “ iwocnfig” command. Output: If the interface is up and active, you will get the “Device or resource busy” error. Step 1: Enter Superuser Modeįirst, enter into superuser mode otherwise, we will get permission to do this.Ĭommand: “ su” Step 2: Create Monitor Mode Let us assume that the name of the Wi-Fi interface is “ wlp2s0,” as shown in the screenshot. There are different commands that you can use, but to use a simple method first, we will try using the “ iwconfig” command to create monitor mode. In previous sections, you saw that the Wi-Fi interface default mode is “managed.” To capture a wireless packet, we need to convert the “managed” mode to “monitor” mode.

If it is not installed, then use the commands “ apt-get update” and “ apt-get install wireshark” to install Wireshark on your system. Open the terminal and run the command “ wireshark –version.” If Wireshark is installed, then there should be a version name with many details, as in the following screenshot: Open the terminal and run the command “ iw phy0 info” or “ iw list.” There is a huge list of information available here, but we just have to check the section for “ monitor.” If the device does not support monitor mode, then it will not be possible to sniff the wireless packet using Wireshark. This is a must, or you cannot sniff wireless packets using Wireshark. The Wi-Fi card must support monitor mode to be able to sniff out wireless packets. By default, the mode is “ Managed,” which means that it is a client or station mode.“IEEE 802.11” is the indication for the Wi-Fi interface.In this example “wlp2s0” is the interface name for the Wi-Fi card. The following screenshot shows the output of this command: To check whether you meet this requirement, open the terminal using the shortcut Alt+Ctrl+T and run the command “ iwconfig.” This output should show if there is an operable Wi-Fi interface. Setup Checkīelow are the requirements for capturing Wi-Fi packets using Wireshark. There are some steps to be followed to achieve this. To follow this article, first, you should learn the basics of WireShark in the Wireshark Basic article, and then you can come back here.
#Wireshark capture wifi traffic how to#
So the idea is to get all the traffic on a secured WPA2 access point, if you know everything and you even have access to the router.In this article, you will learn how to capture wireless frames using Wireshark in Linux (Example: Ubuntu. How can I monitor all the traffic on the network (decrypted, and from all IPs) if I have the password, and I can even get a 4 Way handshake if it's needed.Įdit -> Preferences -> Protocols -> IEEE 802.11 -> New -> wpa-psk and in the Key box: "AP:password" but I get an Invalid key format error.
If I set it for my real wireless card, I get traffic but only from my IP address. I've started wireshark with mon0, and there were only encrypted wireless 802.11 packets. I've first set my wireless network in monitor mode (I am using Manjaro linux, and I've set it into monitor mode with airmon-ng), and I've tried to see the traffic. I have 3 laptops in here, and I want to capture all the traffic from the router with Wireshark.
I have a wireless network, with a WPA2 password. Ok, so I want to do some tests on my network.
