Seeking more knowledge here of authentication and encryption. Currently remotely diagnosing a training room with six identical (cloned) mini-PCs connected currently to an hAP ax lite LTE6. Three of them have connected using WPA2-PSK and three using WPA3-PSK.
What situation leads to them negotiating different authentication types? They’ve all got very similar signal strengths.
Since the OS Controls the used authentication type which OS are the PCs running?
Windows?
Other thing to check (assuming they are indeed identical):
if those wpa2 devices were previously connected via wpa2 on that SSID, they will "remember" it and reuse that encryption method.
Unset wifi network, connect again and normally they should choose wpa3 then.
What if you use an SSID with only wpa3 ? Will they all 6 connect to it ?
Windows 11 Pro
They really are built identically. They only went in a few months ago as part of the replacement of Windows 10. I had 30 of them to deploy so used sysprep and Macrium Reflect to clone them.
Good idea about trying just WPA3-PSK… am doing remotely so thank goodness for safe mode!
Later yes, they can all work on just WPA3-PSK so the question is still why did some of them negotiate WPA2-PSK when WPA3-PSK was available.
Ahh an example where safe mode only sort of helped. Changing authentication caused the Wi-Fi connection to drop and re-connect which meant WinBox lost connection so it restored the original configuration.
Well, then it wasn't just "remotely", it was "remotely and wirelessly"...
There is also something like "Don't cut the branch you're sitting on"
Not end of world as there is somebody on the site at the moment 
Am now wired…
Being wired is weird nowadays
