Hallo,
Ich bin Kaddem85, ein Franzose, der in Deutschland lebt. Deshalb mache ich einige Fehler auf Deutsch. Entschuldigung im Voraus… Ich benutze Ubuntu seit 2010 und es gefällt mir sehr. Zur Zeit benutze ich Ubuntu 13.10. Aber seit einer Woche habe ich ein Problem mit W-lan. Ich erkläre die Situation : In meiner Wohnung, die ich miete, habe ich nur W-lan und keine Drahtverbindung. Kein Problem mit meinem netbook aber ich habe auch einen Personalcomputer, den ich benutzen möchte. Deshalb habe ich ein USB « Wireless Adapter » gekauft. Es handelt sich um den Realtek 8192cu. Leider gibt es ein Problemchen : es funktioniert gar nicht. Hat jemand eine Idee des Problems ? Ich gebe euch die technischen Kennzeichen meines Computers.
