![]() Incidentally, it’s possible that the “iwconfig wlp3s0 channel 10” will output an error, which usually means the channel isn’t available. Execute the “ iwconfig” command to check that your channel is set up and in Monitor Mode.Īssuming this command works, you’re ready to configure Wireshark to capture Wi-Fi traffic.Type “ iwconfig wlp3s0 channel 10.” Remember to change “wlp3s0 to your Wi-Fi interface’s name and “channel 10” to your selected channel.Each should have a channel number attached to it (i.e., ), which you’ll use to configure the channel to Monitor Mode. Scroll down the list and select a frequency.So, you’ll need to configure a single one of these ranges of channels for use in Monitor Mode. You’ll see both sets of frequency ranges if your Wi-Fi card operates on both bands.Įach of these frequencies is a channel number you can use to detect Wi-Fi traffic. If it supports the 5 GHz channel, you’ll see a list ranging from 5,180 MHz to 5,825 MHz. If the card uses the 2.4 GHz radio frequency band, you should see a bullet-point list of frequencies between 2,412 MHz and 2,484 MHz displayed on your screen. Check the listed frequencies to see which channel your Wi-Fi card uses.Press “Alt+ Ctlr + T” to open a new Wireshark terminal. ![]() Thankfully, a simple terminal command shows you the information you need to know: You need to know which channels your card supports before you can capture Wi-Fi traffic. Wireless protocols have a pair of radio frequency bands – 2.4 GHz and 5 GHz – but it’s possible that your Wi-Fi card only supports one of these two channels. From there, use the above steps, and you should be able to configure the interface into Monitor Mode. If you already have an active Wi-Fi interface, the third step of the above process may deliver an error message that reads, “Device or resource busy.” If that happens, you can enter the command “ ifconfig wlp3s0 down” (again – replace “wlp3s0” with your interface name) to deactivate the Wi-Fi interface. Type “ iwconfig” again to check that your Wi-Fi interface is now in Monitor Mode.Remember to replace “wlp3s0” with your Wi-Fi interface’s name. Enter “ iwconfig wlp3s0 mode monitor” into the terminal.Type “ su” to enter superuser mode, which gives you the authority to change Wi-Fi interface modes.Press “Alt + Ctrl + T” to open a terminal.You should see the name appear in the details you generate when you check your Wi-Fi interface.Īssuming you have your interface name ready, follow these steps to switch the interface from “Managed” to “Monitor” mode: This example assumes that your Wi-Fi card’s interface name is “wlp3s0,” though you’ll have to substitute this with your own card’s name. You’ll need to change that to Monitor Mode to capture Wi-Fi traffic. When you checked your Wi-Fi interface, you likely saw that it’s set to “Managed” mode. If it isn’t, you’ll likely need to replace your Wi-Fi card with one compatible with Monitor Mode. If “monitor” is on the list, your Wi-Fi card supports the Monitor Mode necessary to sniff and capture Wi-Fi traffic. Check for the presence of the word “monitor” in the “Supported Interface Modes” list.Type either of the following commands into the terminal:.Use the “Alt + Ctrl + T” button combination to open a Wireshark terminal.You can check this by following the below steps: ![]() ![]() Your Wi-Fi card has to support Monitor Mode. ![]() Step 2 – Check Your Wi-Fi Card Supports Monitor Modeĭetecting a Wi-Fi interface doesn’t automatically mean that Wireshark can capture Wi-Fi traffic. ![]()
