[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 ?

Franchement je ne saurai pas te dire pourquoi.

En tout cas, je suis content pour toi que cela ait fonctionné weimann23, bonne continuation sur Gnu/Linux
