Perte de ma connexion wifi

Bonjour,

Depuis quelques jours je perds ma connexion wifi sans savoir pourquoi.
Le seul moyen que j'ai trouvé pour la récupérer est de redémarrer mon système.
Est-ce que quelqu'un aurait la commande pour redémarrer le service qui va bien ?!

Sinon en regardant dans les logs kernel, j'ai ceci qui apparait à chaque fois, et qui se répète à l'infiini.

Je pense que cela est du à une mise à jour que j'ai fait, mais je ne sais pas laquelle...
Peut-être sur le kernel ?! Ma version est la suivante: 3.0.0-13-generic

D'avance Merci pour votre aide

Re : Perte de ma connexion wifi

Houllà, j'en suis à la 2.6.32
Que te donne les logs

tail -f /var/log/syslog

  après avoir désactivé le wifi 

ifconfig wlan0 down

et reactivé

 ifconfig wlan0 up

?

Re : Perte de ma connexion wifi

Merci de ton aide.

Bon pour l'instant ça va mieux et je ne sais pas trop pourquoi.
Si jamais le problème revient j'essayerai tes commandes.

Merci

Re : Perte de ma connexion wifi

si ton wifi est configuré dans /etc/network/interfaces tu peut tenter un :

sudo /etc/init.d/networking restart

à savoir le fichier /etc/network/interfaces est expliqué ici
