wifi disparu suite mise à jour ubuntu 16.04 d'aujourd'hui

shadock13

bonjour,

suite à la mise à jour d'ubuntu 16.04 aujourd'hui, après redémarrage (comme demandé en fin de mise à jour), je n'ai plus de wifi (je n'ai même plus l'onglet wifi qui apparait dans le menu réseau c'est comme si le wifi n'existait plus du tout sur mon pc! la mise en veille à la fermeture de l'écran (portable lenovo thinkpad) bloque tout, je suis obligée de redémarrer au bouton, la présentation du bureau a légèrement changé (les couleurs).
j'ai fait cette mise à jour ce matin sur mon pc de bureau (tour dell vieux modèle) qui est configuré à peu près de la même manière et ça n'a posé aucun problème.
là, je me suis re-connectée en redémarrant et en choisissant un ancien kernel dans le menu otion avancée ubuntu. (d'ailleurs j'ai pris la version avec le numéro précédent, mais il y a aussi au le même numéro "upstart" et le même numéro "recovery mode", j'ai pris celui sans rien, mais je ne connais pas la différence, si vous pouvez m'éclairer là-dessus aussi).

merci de votre aide!

J'ai eu un problème similaire (plus wifi apres install du kernel 4.4.0-77), j'ai résolu en réinstallant le driver proprio.

shadock13

comme seebz, c'est le kernel 77 qui merde, j'ai pris le 75.
peux-tu me dire exactement ce que tu as ré-installé comme driver?

j'ai fait le wifichek :

Pour cette carte wifi :

Intel Dual Band Wireless-AC 3165 Plus Bluetooth [8086:3166] (rev 99)

voir : ubuntuforums.org/showthread.php?t=2336946

shadock13

il faut que je fasse toutes les commandes indiquées dans ce post?
est ce que je peux commencer par ré-installer mon driver, comme dit seebz? si oui, comment je dois procéder?

xubu1957

Regardes dans la Doc : [doc]gestionnaire_de_pilotes_proprietaires[/doc]

shadock13

j'ai regardé mai sje ne vois pas comment faire.
dans les pilotes additionnels, j'ai :

je ne vois pas comment on désinstalle pour ré-installer.

xubu1957

Il n'y a pas de pilote wifi propriétaire proposé.

Je crois que seebz a une carte wifi Broadcom BCM43142.

D'après cette discussion : Wifi intel nuc [RÉSOLU]

Il faut télécharger le pilote de la carte wifi Intel 3165 : drivers/iwlwifi#firmware

shadock13

je ne suis pas très à l'aise avec tout ça...

est ce que j'essaie d'abord ça (cf ton lien sur un post anglais) :


echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

et si oui, il faut que je copie/colle ligne à ligne?

ou est ce que j'exécute le driver une fois téléchargé? je double-clic sur le fichier téléchargé? comment ça va se passer avec le driver déjà installé? il y en a bien un? il faut le désinstaller dans le gestionnaire de paquets?
est ce qu'il n'est pas possible qu'il y ait une nouvelle mise à jour qui règle tout ça??? (l'espoir fait vivre 😉 et ce serait tellement plus simple pour moi 🙂)

merci et désolée pour toutes ces questions qui paraissent peut-être bêtes.

xubu1957

Bonjour,

Je ne me sers pas du wifi, et je ne connais pas la solution.

Il faut attendre l'aide d'autres membres du forum.

shadock13

bon, alors finalement, j'ai copié/collé les 3 lignes de codes du post précédent et ça semble avoir résolu le problème!
donc, xubu1957, pour qqun qui n'utilise pas le wifi, tu m'as bien aidée 😉 merci 🙂

xubu1957

Bonjour,

Dans ce long message : forum.ubuntu-fr.org/viewtopic.php?pid=17659711#p17659711

ytreza a écrit...
11n_disable=1 : Applicable au driver "iwlwifi"; Désactive la norme Wi-fi N, Ce qui signifie sacrifier de la rapidité en échange de stabilité en se limitant sois-même à la vitesse de la norme G (54 Mbps max.)
...

tu as une explication pour la première ligne des commandes.
