Problemlösung
Keine Ahnung... 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
