RESOLU perte du wifi après mise en veille ubuntu 16.04

Bonjour. La connexion WIFI ne se rétablit pas après une mise en veille alors que "activer le réseau" et "activer le réseau wifi" sont visibles sur l'icône en haut de l'écran. Solution : reboot.
Quelqu'un a-t-il une idée de solution ?

Re : RESOLU perte du wifi après mise en veille ubuntu 16.04

Bonjour,

Dans la documentation : wifi_liste_carte

Atheros AR9285     Reconnue par défaut.  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

Re : RESOLU perte du wifi après mise en veille ubuntu 16.04

Bonjour
Le canal de ma wifi est le 9
Après une veille, l'impossibilité de retrouver la connexion wifi est aléatoire. Ca allait bien toute la journée et ce soir j'ai dû re-démarrer l'ordinateur après avoir tapé la commande echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.conf qui a affiché à l'écran "options ath9k nohwcrypt=1" mais n'a pas rétabli la connexion
Cordialement

Re : RESOLU perte du wifi après mise en veille ubuntu 16.04

Bonjour,

Avais tu passé la deuxième commande ?

Re : RESOLU perte du wifi après mise en veille ubuntu 16.04

Bonjour
Je ne l'avais pas passée. C'est maintenant fait.
Voici l'affichage du résultat de la commande :

sudo echo ath9k » /etc/modules
[sudo] Mot de passe de gilles : 
ath9k » /etc/modules

Réponse bizarre non ? En espérant que ça corrige.

Re : RESOLU perte du wifi après mise en veille ubuntu 16.04

Réponse normale.
Redémarre.

Re : RESOLU perte du wifi après mise en veille ubuntu 16.04

Bonjour,

Pour information :

Correction de la commande, suite à un signalement de moko138 , dans une autre discussion : Voir deuxième correction :

sudo echo ath9k >> /etc/modules

au lieu de cette commande erronée :

sudo echo ath9k » /etc/modules

_ _ _

Même après correction de la faute de frappe, la commande
sudo echo ath9k >> /etc/modules   sera refusée par le système.

Par contre,

echo ath9k | sudo tee -a /etc/modules

sera acceptée.
