No connection to a WPA3-SAE / WPA2-PSK WiFi network

Does nog connect tot a Odido Zyxel T56 modem.

Do you really need WPA3 ? - If not just reconfigure the AP to use WPA2-PSK only. The limitation seems to be within aarch64 and not necessarily an issue with rAudio.

Unfortunately I can only choose between WPA3-SAE / WPA2-PSK and WPA3.

I found a forum article here https://bbs.archlinux.org/viewtopic.php?id=292059 which may give you a way forward. I haven't confimed it myself as I haven't enabled WPA3 on my setup. Good Luck.

Thx. Mark.
I found:
Mixed WPA2-PSK/WPA3-SAE access points will require an alternative setting for key_mgmt as shown below:

ssid="network SSID"
key_mgmt=WPA-PSK-SHA256
psk=xxx
ieee80211w=2

But i have to little knowledge to go on.

You need to modify /usr/lib/netctl/wpa - look for the section that looks like this:

      wpa)
        echo "key_mgmt=WPA-PSK SAE"
        echo "ieee80211w=1"
        if [[ "${#Key}" -eq 64 && $Key == +([[:xdigit:]]) ]]; then
            echo "psk=$Key"
        else
            echo "psk=$(wpa_quote "$Key")"
        fi
  

(was around line 230 onwards in mine) and edit the two echo lines to match your requirements - e.g.

      wpa)
        echo "key_mgmt=WPA-PSK-SHA256 SAE"
        echo "ieee80211w=2"
        if [[ "${#Key}" -eq 64 && $Key == +([[:xdigit:]]) ]]; then
            echo "psk=$Key"
        else
            echo "psk=$(wpa_quote "$Key")"
        fi
  

The ssid and psk values come from your netctl profile (which you should already have set up from previously) but you can check by using:

netctl list
to give you a list of profiles stored on the system, and then:

netctl edit <profile>
if you need to modify it.

As I have already mentioned, I haven't done this on any of my systems as I am happy to use WPA2 for the time being. Backup as you go and you should be able to recover if it all turns out messy.

Good luck!
