I just installed Linux Mint 18 with Cinnamon DE. I'm really happy with it, but I have a problem and I cannot solve it.

I'm not able to edit the Wi-Fi parameters after adding them and discover that something has to be changed.

In other words, I cannot find an Edit button in the Network Manager interface.

In the following picture, I have to change some parameter of the second Wi-Fi. But it continues to trying to connect with wrong parameters..

  • Not really a duplicate. I'm not trying to edit A hotspot connection while I'm trying to edit the Wi-Fi connections parameters. E.g. if I set a wrong password I cannot undo this and set another one – matteo Nov 21 '16 at 15:17

Click Known Networks and activate the misbehaving connection. Click Forget Network at the bottom left. Reconnect using the proper settings.

  • Thanks! It works for some networks.. But I have one connection (eduroam) that, when I click to connect it it does not ask me any setting anymore – matteo Nov 22 '16 at 7:56

You can use nmtui to edit your network from the terminal, Open the terminal then run nmtui:

  • Thanks for the answer.. I think the problem is different, e.g. with eduroam I cannot set the initial parameters (user, password, etc) so it try to connect without them and it fails. – matteo Nov 22 '16 at 11:00

If your problem is that you can't change the wifi password maybe you encounter the same problem as me.

I don't know why but if I choose to store the password only for me, the password won't change. The solution for me is to ask Linux Mint to store the password for all users.
