Pas d’interface wlan0 après la désinstallation de Ubuntu 13.04

J'utilise Lenovo ThinkPad Edge 14 0578

Bien. J'ai commis une erreur très stupide telle que beaucoup de paquets importants sont supprimés (la cause ne peut pas se connecter au réseau, ni au câble météo ni au réseau sans fil). Par conséquent, je n'ai pas d'autre choix que de réinstaller avec le DVD.

Lors de la réinstallation, j'ai branché le câble LAN et il est indiqué qu'il peut accéder au réseau. Cependant, après la réinstallation, la connexion filaire est correcte mais pas sans fil.

Avec ifconfig wlan0 up

wlan0: ERROR while getting interface flags: No such device

Et iwconfig

eth0      no wireless extensions.

lo        no wireless extensions.

Mais en réalité, la puce existe.

En gros, cela ressemble à des problèmes de pilotes/modules. Vous pouvez utiliser les éléments suivants pour déterminer quel module est associé à votre composant sans fil:

lspci -vvnn

Charger ce module:

modprobe [module name]

Vous pouvez définir les modules chargés au démarrage dans /etc/modules. Ajoutez votre module sans fil à ce fichier et redémarrez.
