WLAN mit Notebook und Squeeze

[adibaba]

Hallo,

heute habe ich mir Squeeze installiert. Leider bekomme ich keine WLAN-Verbindung. Bin jetzt schon stundenlang am Suchen, vielleicht könnt ihr mir helfen. Ich möchte meine Netzwerk-Verbindungen über den network-manager verwalten lassen.

Hier ein paar Daten:

Wahrscheinlich muss ich firmware/treiber/kernel module installieren, da ich bisher keine treiber hinzugefügt habe. Allerdings habe ich wenig Erfahrung mit Hardware-Sachen. Dell bietet auch ein eigenes Repository an, ich würde das allerdings gerne ohne Fremdquellen erledigen, wenn so keine Vorteile verloren gehen.

Ach so,

die kabelgebundene Netzwerkverbindung funktioniert.

Hey habakug,

das war es. Ich hatte schon per aptitude search firmware gesucht, hatte die non-free quellen aber noch nicht drin.

Danke dir vielmals!
