You can see detailed information about the hardware using: In my case (and most likely for most typical computers) the hardware is phy0 and my network interface is wlan0. To see the list of devices, and interfaces for each device: wlan0, similar to an Ethernet eth0 interface). I still like and use the old interface of iwconfig, but iw seems to be much more powerful for viewing/configuring wireless information.įirst be aware that iw distinguishes between wireless LAN hardware devices (the physical layer, referred to as phy) and the network interface configured to use that hardware (e.g. The command iw is meant to replace iwconfig. Here I present a third option: again using the command line in Ubuntu Linux but with the command iw. This includes data packets send between other devices, something which is not possible unless your device is in monitor mode. Both involve putting the wireless LAN card into "monitor mode", allowing you to view and record all packets sent by other WiFi devices nearby. I previously showed two ways to capture wireless LAN packets in Ubuntu Linux: using the command line tool iwconfig and using Kismet. Capturing Wireless LAN Packets in Monitor Mode with iw
