When I run the command ifconfig in the terminal, I get three results: lo, virbr0, wlo1.

  • What is wlo1? Is it useful?

    Presumably your wireless card. Add the output of iwconfig and sudo lshw -C network to the post, please.

wlo1 is a wireless network interface (NIC). You can use the command iwlist scan to scan the wireless NICs for available WiFi SSIDs.


iw is the preferred tool when querying WiFi devices. You can also use NetworkManager's CLI tool, nmcli, or if you're on an older version of Linux, use iwlist.

$ iw dev wlan0 scan

iwlist (older cli)
$ iwlist scan
enp2s0    Interface doesn't support scanning.

lo        Interface doesn't support scanning.

  • BTW, iwlist etc. are the old tools, the newer tool is iw. Some features will only be accessible via iw.
