Bonjour,

Vu la carte wifi et son pilote :

etwork controller [0280]: Qualcomm Atheros AR93xx Wireless Network Adapter [168c:0030] (rev 01)
        Subsystem: Qualcomm Atheros AR93xx Wireless Network Adapter [168c:3112]
        Kernel driver in use: ath9k

Essaies la procédure donnée pour la carte Atheros AR9485 dans la Doc [doc]wifi_liste_carte[/doc]

§ 3.1 Atheros a écrit Les cartes WIFI Atheros fonctionnent plus ou moins facilement sous GNU/Linux Ubuntu au gré des versions. Un pilote unique est utilisé pour tous les modèles, le module ath5k ou ath9k. Parfois, ce pilote ne fonctionne que partiellement et des réglages/optimisations sont nécessaires selon les modèles de cartes.

En cas de lenteur, dans l'interface de configuration de votre routeur, vérifiez le canal utilisé : s'il est en mode "automatique", tentez d'attribuer un canal manuel inférieur à 10. ou essayez la commande :
echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.conf
En cas de difficultés persistantes on peut essayer de faire charger le pilote au démarrage avec la commande :
sudo echo ath9k >> /etc/modules

Merci pour la réponse, mais déjà fait tout ça :/

xubu1957

Tu avais vu : 17-04-wi-fi-not-working-mac-address-keeps-changing ?

nop mais j'ai pas l'impression que ce soit lié, et je n'utilise pas network manager, je suis en ubuntu server

xubu1957

uname -r -m

C'était un noyau à problèmes > Le noyau 4.4.0-67 semble bogué : perte de réseau

ark42

ah oui bien vu, je vais tenter une maj, même si je crains que j'avais déjà le problème avec des noyaux précédents.

ark42

bon.. pas mieux ^^

Je n'ai plus d'idées. 🙁

Pour un petit nettoyage :

moko138 a écritPour supprimer tous ces fichiers de configuration devenus sans objets et marqués "rc", et uniquement ces fichiers,
exécute :

dpkg -l | grep ^rc | cut -d' ' -f3 | xargs sudo dpkg --purge

et après :

dpkg -l | grep -Ei "linux-(g|h|i|lo|si|t)"

Sur un serveur, je ne sais pas quoi conseiller pour une gestion des noyaux.

Bonjour,

Tu es bien sous xenial (16.04) alors je vois mal pourquoi il y a encore linux-generic-lts-vivid, il faudrait le supprimer :

sudo apt purge linux-generic-lts-vivid

Et tu dis être passé à un noyau 4.10 : comment as-tu fait ? Installé manuellement ?

ark42

xubu1957: nettoyage fait! merci.

Le noyau 4.10 je l'ai installé depuis les dépots.

linux-image-4.10.0-27-generic:
  Installed: (none)
  Candidate: 4.10.0-27.30~16.04.2
  Version table:
     4.10.0-27.30~16.04.2 500
        500 http://fr.archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu xenial-security/main amd64 Packages
        100 /var/lib/dpkg/status

J'ai rollbacké depuis :x je teste un dongle usb wifi en parallèle et j'avais besoin de repasser en 4.4 pour compiler le driver.
Et ma connexion est + stable avec cette clé d'ailleurs, juste le débit qui est lent maintenant...

Sinon tu as raison pour vivid, elle est toujours là d'avant, le release-upgrade d'ubuntu ne doit pas nettoyer les vieux noyaux, je le purge.

Merci
