Check whether the wireless network card supports the monitoring mode.
When implementing the wireless penetration test, it is usually necessary to set the wireless network card to the monitoring mode to monitor all traffic passing through its network card. For many users, the university IT masters do not know how to determine whether their wireless network card supports monitoring. As a result, a lot of time is wasted doing useless operations. To help users provide work efficiency, you can use the iw list command to check whether the wireless network card supports monitoring before using the wireless network card to save unnecessary time. The execution commands are as follows: After executing the above command,
iw list
will output all the function information of the device. As shown below:
