The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

[<address@concealed>]

Hi Wenche

 

Thanks for your repsonse and you are right concerning WPA3, but based on a lot of recent tests on my side with Wi-Fi 6E and different OS’, Windows does handle this setting as follows:

 

Set to WPA2-Enterprise: at least WPA2-Enterprise is required on the SSID, but Windows will «upshift» to WPA3-Enterprise, if available on the SSID (important: the CAT eduroam installer puts «WPA2-Enterprise» as the default value when executed as well and it works on Wi-Fi 6E)

 

Set to WPA3-Enterprise: WPA3-Enterprise is required, Windows does not «downshift» to WPA2-Enteprise, if the SSID only propagates WPA2 à SSID association fails in this case

 

Hope to help someone with this hint.

 

Best regards

Dominic

Hi,

 

IIRC, Wi-Fi 6E requires WPA3, in the screenshot you seem to have WPA2. 

 

Regards,

Subject: [[cat-users]] Question / SSID eduroam w/ and w/o CAT eduroam installer on Windows 11

 

Dear cat users mailing list

 

I am in the middle of troubleshooting an eduroam problem on Windows 11. I myself are experienced on the networking side, but only have limited knowledge of Windows (11). Because I simply cannot find the root cause or a solution to the problem, I am taking the liberty of contacting this mailing list...

 

In short, the problem only occurs in combination with Wi-Fi 6E (6 GHz):

 

1. if I let the WLAN profile for eduroam be configured by the CAT eduroam installer, everything works perfectly and the client can authenticate against the SSID immediately

 

2. if I manually configure the WLAN profile for eduroam with EXACTLY the same settings as with the CAT eduroam installer (1), the client fails to authenticate against the SSID or «runs» into a Dot1X authentication timeout (does not send any credentials) respectively. Those are the settings implemented by the CAT eduroam installer for our eduroam profile and also configured manually (sorry, is in German only):

 

 

 

 

 

 

 

My question would be: am I missing an important configuration in Windows 11 OR what else does the CAT eduroam installer configure in Windows 11, so it works with our eduroam SSID on Wi-Fi 6E as well? Any idea or recommendation would be appreciated.

 

Thanks a lot in advance and best regards

Dominic
