Bonjour,
 
Je me suis monté un pc qui me sert de seedbox sous XUbuntu 13.10, le problème c'est que ma clef wifi se met à bugger au bout d'un moment, le voyant de la clef s'éteint, et la connexion est perdue.
 
En fouillant dans les logs j'ai trouvé ca :
 
/var/log/syslog :

Je ne sais pas si ca viens de ma clef qui est défectueuse ou si le probleme est logiciel...  
Est-ce que quelqu'un aurais une idée svp ?
 
Merci d'avance
