[RESOLU] impossible d'activer le reseau sans fil
Bonjour,
D'un coup d'un seul, mon réseau sans fil s'est désactivé, comme si le commutateur matériel ne marchait pas...C'est la deuxième fois que cela arrive.
Merci.

Re : [RESOLU] impossible d'activer le reseau sans fil
Bonjour weimann23,
Essaies ceci :
sudo rfkill unblock all
Puis essaies d'actionner l’interrupteur du wifi (ou par touche) puis reboot

Re : [RESOLU] impossible d'activer le reseau sans fil
Tout simplement...Ca marche....
Merci.
P.S: j'avais deja fait cette manip il y a un mois. Comment s'explique le fait que le wireless se "block" de temps en temps ?
