Le pilote Intel Wireless 7260 se bloque, comment puis-je le contourner?
J'ai des problèmes avec le Wi-Fi sur mon Xubuntu 13.10 et mon nouvel ordinateur portable Lenovo X240. Parfois, le conducteur se bloque.

J'utilise le dernier noyau Xubuntu

Merci de votre aide.
Il existe un fichier de microprogramme plus récent censé remédier à certaines instabilités. Veuillez ouvrir un terminal et sauvegarder votre firmware actuel:
cd /lib/firmware
Sudo mv iwlwifi-7260-7.ucode iwlwifi-7260-7.ucode.bak
Maintenant, téléchargez le nouveau firmware:
Sudo wget https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode
Maintenant, déchargez et rechargez le pilote pour voir le nouveau firmware:
(Notez que le module iwlwifi charge le module iwldvm ou iwlmvm en fonction du système. Vous devez donc supprimer le module correct avant de pouvoir supprimer iwlwifi. J'ai utilisé iwldvm, mais vous devez utiliser iwlmvm si vous n'obtenez aucun résultat avec la commande lsmod | grep iwldvm.)
Sudo modprobe -r iwldvm
Sudo modprobe -r iwlwifi
Sudo modprobe iwlwifi
Il n'est pas nécessaire d'exécuter Sudo modprobe iwl?vm car iwlwifi s'en chargera automatiquement.
