Other posts seems to be addressing more complicated network connection issues from the command line.

The Unity panel Network indicator/button doesn't respond too well sometimes - it keeps trying to connect to a network even when i click on "disconnect", stuff like that.

So I want to go command line for the control. I don't like GUIs anyway.

Is there not some simple command line tool which can do something like the following?

wifi connect MyNetworkNameA
wifi disconnect
wifi connect MyNetworkNameB

I think you want to keep using managed interface (by NetworkManager). nmcli is a command‐line tool for controlling NetworkManager.

  • To see list of saved connections, use (<SavedWiFiConn>)

    nmcli c
  • To see list of available WiFi hotspots (<WiFiSSID>)

    nmcli d wifi list


    sudo iwlist wlan0 scanning
  • To see list of interfaces (<WifiInterface>)

    ifconfig -a

Just change <WifiInterface>, <WiFiSSID>, <WiFiPassword> in the following commands to reflect your setup. If WiFi info already saved, easier way using <SavedWiFiConn> name of connection as it was saved in NetworkManager.

Ubuntu 16.04

nmcli d disconnect <WifiInterface>

nmcli d connect <WifiInterface>

Another way:

nmcli c down <SavedWiFiConn>

nmcli c up <SavedWiFiConn>

Ubuntu 15.10 & previous

nmcli d disconnect iface <WifiInterface>

nmcli d wifi connect <WiFiSSID> password <WiFiPassword> iface <WifiInterface>

Another way:

nmcli c down id <SavedWiFiConn>

nmcli c up id <SavedWiFiConn>

If your password isn't automatically recognized type this:

nmcli -a c up <SavedWiFiConn>

Reference: man nmcli

    Works like a charm! And, as suspected, the command line responds immediately, while the GUI can be sluggish, uncooperative, and unresponsive sometimes. – cmo May 6 '14 at 15:55

    Saved my day when I lost my Unity dash and taskbar, and the Network Settings dialog kept on crashing upon any kind of network connection establishment. – Janaka Bandara Nov 27 '14 at 1:21

    @kirill_igum , sorry to be late quiet busy, You may use cron for scheduling wifi scan using iwlist wlan0 scanning or nmcli d wifi list then nmcli to connect to the corresponding wifi network depending on your needs. – user.dz Jan 11 '16 at 21:59

    The command that I was issuing was giving an error. I was issuing this command: nmcli c up id "Apollo III Connect" It gave an error. When I leave out the word id and typed this it connects without error: nmcli c "Apollo III Connect". I understand how to connect it now. You're saying id as the parameter and saying replace the word id with the name of the connection, which you are naming <WiFiConn>. Thanks! – L. D. James Jun 15 '16 at 22:48

    To save a connection setup: sudo nmcli dev wifi con "SSID_NAME" password PASSWORD "CONFIG_NAME" To find auto your saved connection setups: nmcli c – Cirelli94 Apr 13 '17 at 13:05


Great interactive ncurses network manager option. Comes in the same package as nm-applet (the default top bar icon thing) and nm-cli, and is therefore widely available. Screenshot:

Tested in Ubuntu 17.10.

  • Thanks! For some reason, my Ubuntu refused to connect to Wifi, so I plugged in the Ethernet cable and clicked Activate on Wired Connection and BAM! – asgs Nov 2 '17 at 15:12

    works on Ubuntu 16.01 as well, cool solution! – Jan Sila Dec 1 '17 at 8:57

    This is a much more intuitive solution than what is above IMO. Unless you're trying to learn how Linux/Unix connects to WiFi, this seems like the ideal select and press enter solution. Works well on Ubuntu 18 – jamzsabb Jun 18 '18 at 18:56

If your wi-fi access point is saved, it will auto-connect. Turn wireless on or off with a simpler command:

nmcli nm wifi on
nmcli nm wifi off

on newer version:

nmcli radio wifi on
nmcli radio wifi off

For reference, see man nmcli.

  • Yep, this the best (simpler then mine :) ) when working with single WiFi network. – user.dz Apr 13 '15 at 8:27

    How do you make NM enable wifi automatically during boot? Every time I reboot, Network Manager starts with wifi disabled. – Cerin Jul 25 '15 at 21:46
  • @Cerin, you may try adding this command to startup applications, see askubuntu.com/questions/243139/… – user.dz Jan 11 '16 at 21:47

    Note the nm option has been removed or replaced (?) in newer versions of nmcli – dgorissen Mar 18 '16 at 14:30

    @dgorissen, yes it seems changed on newer version, replace nm with radio. I've updated this answer. – user.dz Apr 1 '16 at 18:31
