WLan unter Linux mit gleichzeitiger WEP/WPA verschluesselung

KervyN · Nov 24, 2008

Hi Guys.
Ich hoffe ich finde hier einen findigen der vielleicht ne Antwort auf eins meiner Probleme hat.

Also folgendes. Ich hab hier einen Router der Firma SMC stehen, und der hat WEP und WPA gleichzeitig aktiv.
Unter Windows hab ich keine Probleme zu connecten. Aber unter Linux bekomm ich einfach keine Connection. Ich kann aber ohne Probleme auf meiner Arbeit ins WLan. Dort haben wir eine WPA Verschluesselung. Und ich kann auch ohne Probleme auf eine WEP Verschluesselung zugreifen.
Vielleicht hat ja einer von euch eine gute Idee. Ich hab hier mal meine Arbeitsschritte reingestellt.

Als Hardware nutze ich ein Acernotebook welches wirklich komplett unter Linux eingerichtet ist.Zur auswahl hab ich ein Kubuntu 8.10 und eine openSuSE 11.

Die, meiner Meinung nach, interessanten Zeilen sind:
20; 44-47; 105-110

Edit:
Argh Dummheit von mir. Hab das WLan Forum einen weiter unten nicht gesehn. Sorry -_-
Wer lesen kann ich klar im Vorteil. Bitte verschieben

Meiner Meinung nach ist es sogar eher ein Linuxproblem, da es unter Win ja bei dir läuft, daher hab ich es mal nicht nach Wlan verschoben sondern nach Linux

bitmuncher · Nov 25, 2008

@lightsaver: Ich denke auch, dass es hierher gehört.

Du hast den falschen Group-Cipher-Wert in der wpa_supplicant.conf. Dein iwlist-Scan zeigt eindeutig "Group Cipher : WEP-104", du verwendest aber "group=TKIP" in deiner Konfiguration. Die Angabe bei "Group Cipher" muss mit der Option "group=" in der wpa_supplicant.conf übereinstimmen. Ausserdem solltest du bekanntgeben, dass ein Pre-Shared-Key verwendet wird: "key_mgmt=WPA-PSK".
