Offensichtlich kommt die WPA2 Verbindung nicht hoch. Einige Logmeldungen deuten auf Probleme hin "Association request to the driver failed". Aber was fange ich damit nun an und wie löse ich das Problem? Vielleicht mache ich auch ganz andere Fehler. Bin leider noch relativ unerfahren unter Linux... Vielen Dank für Eure Hilfe! Besten Gruß, Marc
