[Résolu] Réseau WIFI disparu du jour au lendemain

Salut à tous,

Je poste ce message car je n'arrive pas à résoudre un problème qui dure depuis deux semaines chez moi.
Je suis parti un week end, et en revenant ma copine m'a dit qu'elle n'arrivait plus à se connecter à notre wifi perso depuis mon ordinateur (on a une BBox), alors qu'elle me dit n'avoir touché à rien (vu qu'elle connait encore moins Ubuntu que moi, je la crois).

En gros, depuis cette date je vois tous les wifis des alentours (y compris provenant d'autres BBox) mais plus le mien (Nommé Bbox - AB5029) ce qui est assez rageant. En démarrant mon ordinateur sous Windows je n'ai pas de soucis pour me connecter, mais sous Ubuntu, il est aux abonnés absents.

Voilà la liste des tests demandés avant de poster, j'ai remarqué une chose étonnante quand je fais sudo iwlist scan (désolé, il y a beaucoup de WIFI...): regardez le contenu de "Cell 15":  ESSID:"". Je n'y connais rien, mais vu que c'était le seul à ne pas porter ce qui semble être un nom, ça m'intrigue...

L'un d'entre vous aurait-il une piste à explorer svp ?
Merci d'avance
