I use Ubuntu 18.04 LTS and I'm having the problem that the classical network manager has as maximum security authentication WPA & WPA2 Personal.

The problem is that I want to have access to networks with WPA3-Personal authentication and I'm not able to connect to them in this moment.

Can someone to explain me how to fix this problem? Maybe the installation of a packet, library or even reinstalling Ubuntu 18.04 LTS will fix the problem? I don't know.

    Please see: ubuntufree.com/… What is the version of NM that you have installed? sudo dpkg -s network-manager | grep Version Welcome to Ask Ubuntu.

  • Hi!, this was the output of the command: Version: 1.10.6-2ubuntu1.4 Apr 2, 2020 at 2:46

Please see these bug reports: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1844422 and also: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1848339 WPA3-SAE capability is included in Network Manager version 1.20-2 and associated packages.

I know of no way, however, to reliably install the later versions of Network Manager, wpa-supplicant, et al on to Ubuntu 18.04 LTS.

I recommend that you install a fully updated version (Ubuntu, lubuntu, kubuntu, etc.) of 19.10. I suspect that WPA3-SAE will then work properly.

  • Thanks for the response but it seems this does not solve the problem at a 100%. I was wondering if you could tell me the commands and the steps I should use on the terminal to install what the bug reports suggest?. I will try them out and tell you the output. Apr 2, 2020 at 14:59
  • I haven't any idea. The commits in the bug reports are to change the source code for Network Manager; thereafter, it is recompiled and a later version number added, for example. network-manager-1.20.4-2ubuntu2.1 becomes 2.2 or some such. This is the packaged in a deb package that, depending on your kernel version and gcc version, installs on your system. The commits are not, as far as I can tell, intended nor usable in NM 1.10-xx. All of this is very far beyond the scope of this answer. Did you try the live session of Ubuntu 19.10 daily build to see if it works?

  • I understand; the thing is 18.04 is a long term supported and 19.10 it not so it may come with bugs that will be fix only until the LTS version. I haven't tried the live version of 19.10. I will try it out and comment the outcome. Apr 2, 2020 at 16:50
  • Well it didn't go well. I booted 19.10 and has the same authentication (Wi-Fi Security) methods as 18.04 LTS. Does anyone know how to fix this?. Apr 2, 2020 at 18:08
  • One of the bug reports suggests that it is working using nmtui. Please try.
