Situation réelle de la question

J'obtiens l'erreur suivante dans le cadre de ce problème aquí mais comme ce problème est totalement différent, je pense qu'il est préférable de le considérer séparément. Mon wlan0 est en panne. Lorsque j'essaie de l'allumer avec

$  sudo ifconfig wlan0 up

SIOCSIFFLAGS: Operation not possible due to RF-kill

et ensuite

$ sudo rfkill list all

0: phy0: Wireless LAN 

     Soft blocked: yes

     Hard blocked: no

1: tpacpi_bluetooth_sw: Bluetooth

     Soft blocked: yes

     Hard blocked: yes

Que signifie le message d'erreur ? Qu'est-ce que le RF-kill ?

Quand j'applique la suggestion de Fossfreedom, j'obtiens "SIOCSIFFLAGS: No such device" . Le noyau, pour une raison quelconque, rejette la carte, comme l'a souligné FF.

Cela peut vous aider ou non mais j'utilise un ordinateur HP et il disait la même chose, alors ce que j'ai fait c'est que mon clavier a un bouton WiFi dessus et je l'ai maintenu enfoncé pendant une seconde et l'icône en haut a disparu et j'ai tapé dans ifconfig wlan0 up Et ça a marché

Désactivez votre connexion filaire et appuyez sur la touche du clavier qui active votre appareil sans fil. C'est ce qui a résolu la même erreur pour moi.

Pour mon ASUS R704V fonctionnant sous Ubuntu 13.10, aucune des propositions ci-dessus n'a fonctionné. Apparemment, les pilotes du noyau et le matériel ne sont pas d'accord sur la signification des niveaux logiques "0" et "1" comme "bloqué" et "non bloqué". niveaux logiques "0" et "1" comme "bloqué" et "non bloqué".

Mais j'ai trouvé un étrange solution qui fonctionne pourtant de manière fiable :

  • suspendre le système en RAM (en appuyant sur la touche SUSPEND ou en utilisant l'entrée Suspend dans le menu Logout à droite du panneau supérieur)
  • attendre quelques secondes
  • appuyez sur le bouton d'alimentation pour redémarrer le système

L'ensemble du processus prendra moins de 5 secondes.

La sortie de 'rfkill list all' montre enfin

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no

Le NetworkManager activera le WIFI et devrait proposer des points d'accès auxquels se connecter.

La solution était aussi simple que d'appuyer sur Fn + F2 pour activer la carte sans fil de mon ordinateur portable Dell.
