You can use different tools to get information about the status of the Wi-Fi interfaces:

- nmcli
- iw
- wpa_cli

## nmcli

To get the status of all devices managed by NetworkManager, use the nmcli tool:

    ~# nmcli dev status
    DEVICE  TYPE      STATE        CONNECTION
    eth1    ethernet  connected    eth1
    wlan0   wifi      connected    wlan0
    eth0    ethernet  unavailable  --
    can0    can       unmanaged    --
    lo      loopback  unmanaged    --
    sit0    sit       unmanaged    --
    wlan1   wifi      unmanaged    --

## iw

To get the status with the iw tool:

    ~# iw dev wlan0 link

            RX: 14188 bytes (110 packets)
            signal: -11 dBm
            tx bitrate: 72.2 MBit/s MCS 7 short GI

## wpa_cli

To get the status with the wpa_cli tool:

    ~# wpa_cli -iwlan0 status
    bssid=84:b5:17:40:a7:c0
    freq=5180
