ich habe einen neuen PC (Debian/Testing) und möchte diesen via WLan und USB-WLan-Adapter Netgear MA111 mit dem Netzwerk und Internet verbinden. Vor einigen Tagen habe ich bereits das dazu erforderliche Kernel-Modul "prism2_usb" erfolgreich installieren können. Und jetzt scheitert leider die WLan-Einbindung (Mit dem Datenkabel also Lan funktioniert es hingegen top). Um die Einbindung zu erleichtern habe ich am Router sämltliche Einstellungen auf "open" und ohne Paßwörter gestellt. Eigentlich ist das WLan also offen wie ein Scheunentor und nichts dürfte einer Verbindung im Wege stehen ... . Aber es geht nicht ;-(
Hier jetzt ein paar der wichtigste(?) Einstellungen und Abfrage:
