Moin moin, ich habe auf einem neuen Rechner frisch Ubuntu 18.04 LTS installiert (mit Kabelnetzwerkverbindung und Installation von Treibern auch aus dritten Quellen on the Fly). Leider wird der WLAN-Chip (scheinbar?) nicht erkannt, jedenfalls habe ich bisher keine Möglichkeit gefunden, das WLAN zum Laufen zu bringen. Ich würde mich sehr freuen, falls ihr mir weiterhelfen könnt.
Vielen Dank und viele Grüße aus dem Norden! Francesco
