I have gone through other questions on connecting to a Wi-Fi network from a terminal. nmcli works from the command line if the password provided is correct. If the password is wrong:

  1. The network manager opens a dialog box asking for the right password
  2. The command doesn't exit till I click on "Cancel" (returns 4 on cancel)

Is there a way to try to connect to a network without having this dialog box pop up if there is an error?

I need this to connect to a Wi-Fi network from a ctrl + alt + F<num> terminal. Here it just keeps waiting and the prompt doesn't return.

  • sounds like a bug, I suggest you file a bug report. You have several alternates, all outlined here - https://help.ubuntu.com/community/NetworkConfigurationCommandLine/Automatic – Panther Feb 24 '16 at 19:56
  • Network manager in full tty environment does print an error on console. You seem to have been trying this only in GUI with terminal emulator. Open tty2 with ctrl+alt+f2 , and try there – Sergiy Kolodyazhnyy Feb 24 '16 at 21:55
  • @Serg - I tried it in tty2; it's the same result. I am not getting the prompt back and when I shift to unity (ctrl + alt + f7) the network manager's dialog box is open. – rohithpr Feb 25 '16 at 03:45
  • I am using timeout to exit. It still opens a dialog box but my program gets to know that something is wrong. Syntax `timeout 30 nmcli ...`. 30 indicates that the command will return after 30 seconds in case of an error. – rohithpr Mar 02 '16 at 15:53

I do not see your Ubuntu release ID and I do not know why you want to avoid the NetworkManager GUI but here is an alternative to using NetworkManager:

  1. Put the connection name and attributes in /etc/network/interfaces. This will cause NetworkManager to ignore this interface as "unmanaged".
  2. See the Answer in ubuntu 14.04 connect to a wifi network using command line
