Hallo,
auch ich bin neu hier und ein konkretes Problem hat mich hergeführt. Denn plötzlich ist die Verbindung zum bisher genutzten WLAN-Netzwerk mit meinem Laptop (Lenovo IdeaPad N581 mit Xubuntu 14.04) nicht mehr möglich. Mittlerweile taucht es auch nicht mehr in der Liste möglicher Netzwerke auf (während andere direkt daneben liegende Geräte problemlos mit dem WLAN verbunden werden können). Jedoch taucht dementsprechend auch das WLAN nicht in den Cells nach dem Befehl "sudo iwlist scan" auf. Genutzt wird eine o2 Homebox 6441 (Seriel Nr. D602200553, Mac Adresse: D463FE11E082, AsJoria Network). Leider konnte ich noch keine passenden Lösungen hierzu im Forum finden, ich hoffe, ihr könnt mir weiterhelfen und habe hoffentlich alle nötigen Informationen zusammentragen können...
