Is it possible to use WPA3 with netplan?

I'm using Ubuntu 20.04.3 LTS and can't connect the wifi using WPA3; I've tried this in /etc/netplan/01-network.yaml:

network:
  version: 2
  renderer: networkd
  wifis:
    wlan0:
      dhcp4: true
      access-points:
        "MYSID":
          password: "mypassword123"

It works ok if I setup the router to use WPA2 authentication, but if I set it to WPA3 it fails. What should I do in order to make this work with WPA3?

Please notice that my question is specifically about using WPA3 with netplan using networkd as a renderer (solutions using NetworkManager is not what I'm looking for)

@ArturMeinild the link you suggested does not answer my question ... I'd like to fix this using netplan, no NetworkManager, thanks anyway

netplan and NetworkManager does not exclude each other - but maybe you mean using netplan with Systemd-networkd as a renderer (which is the other option apart from NetworkManager)?

As long as `wpa_supplicant` is installed, and your router/AP is set to support WPA3, it should all work.

@heynnema, wpa_supplicant is installed but it doesn't connect when the router is set to use WPA3

Yes. I think that if you set the router to WPA2, it'll connect at WPA3 if it can.

With the networkd backend, netplan dispatches wifi security directly to wpa_supplicant because networkd does not have direct support for this. Any WPA3 features that are enabled by default in wpa_supplicant are available. However, if you need to configure WPA3-specific options, such as SAE key management, netplan does not currently support this. You can file a feature request at https://bugs.launchpad.net/netplan.

Probably the issue is the key management, thank you for the information!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
