I also have to enter a password to connect. Not the root password, but a password I created for the DSL connection when installing Ubuntu.
So I would like to get rid of the password and connect automatically at startup.
I suggest you use
Press Ctrl+Alt+T or go to Applications -> Accessories -> Terminal. Run:
Set the username and password.
Now to connect, run this
We really want it to connect automatically though, so edit
That opens the file in a text editor. Before the line that says
Save file and quit the text editor.
Now, reboot the system.
If you want to use Network Manager, see this articlepost:
If you have it set up with a default account that bypasses the login screen then this is an issue with the keyring. You need to go to
System > Preferences > Passwords and Encryption Keys
You need to delete the Default Keyring and set the Login Keyring as default. I think it might require a restart for it to show up.
