I occasionally have to obtain access to the internet and a company network via its WLAN server.
Today I encountered an apparently insoluble problem when logging in from my Laptop to the WLAN server. My password set by the server administrator was consistently rejected.
(WiFi login from my Android smart phone to the same account on the server with the above password worked without a hitch).
On my laptop, I am running OpenSuse Leap 42.2 (64-bit) / Gnome 3.20.2.
I would normally conclude that the authentication settings on the laptop are wrong, but nothing worked. Admin confirmed that all settings are correct.
The server-side error message was:
"“Ursachen code: 22
Der Client konnte nicht authentifiziert werden, da der angegeben EAP (Extensible Authentication Protokoll)-Typ vom Server nicht verarbeitet werden kann.”
My translation: “Root cause, error: 22
The client could not be authenticated, as the given EAP Type cannot be processed.”
The error describes your problem exactly…
When 802.1x is configured (typically corporate WiFi networks), there are a number of encryption types possible, eg MS-CHAP, CHAP, EAP TLS, PEAP, EAPol and possibly many more. You have to configure the client to use exactly the same encryption type as the server.
Then, beyond that will depend on the specific implementation of 802.1x, a client certificate is required.
Sometimes that certificate is distributed and needs to be installed manually and sometimes that certificate is dynamically distributed.
Since it sounds like you didn’t have to work hard to configure your Android, I’m guessing that certificates are dynamically distributed in your network.
The configured values, confirmed by the SysAdmin, are MS-CHAP and no certificate is required. Unfortunately, that produces the error described in my post.
For whatever 802.1x client you’re using,
Locate the local certificate store and manually purge anything it,
Then try again.
Also,
What 802.1x client are you using…
Something, maybe vendor specific or are you using Network Manager?
If another 802.1x client app is available, maybe try that?
No,
I was asking about the wireless access point server,
By identifying the specific access point you’re connecting to, it may be possible to better understand what is required for the Internet connection, perhaps some kind of fine print, even possibly types of clients supported.
