Wifi qui se déconnecte sous Ubuntu 16.04
Bonjour à tous,
Je suis un utilisateur d'Ubuntu depuis presque 10 ans et j'ai un petit soucis de wifi que je n'arrive pas à régler. Je précise que j'utilise le même ordinateur portable depuis mes début sous Ubuntu 8.04 et que ce problème m'arrive depuis que j'ai fait la mise à niveau depuis Ubuntu 14.04 vers la version 16.04.
Voici mon problème. J'utilise le wifi. De temps en temps, lorsque je ne navigue, Firefox n'arrive plus à charger les pages (une page avec un message d'erreur s'affiche). Le wifi fonctionne, mon smartphone y es connecté et je peux accéder à internet. Puis l'icône wifi dans la barre de menu m'indique "connexion désactivée". En cliquant sur l'icône je vois le nom de mon réseau. Et lorsque j'essaye de m'y connecter en cliquant dessus tout les noms des réseaux disponibles disparaissent et l'un de ce trois message d'erreur apparaît (ils sont tous apparus plusieurs fois):
En cherchant un peu sur internet j'ai trouvé la commande sudo service network-manager restart. Mais cela ne fonctionne pas. Le seul moyen de retrouver une connexion fonctionnelle est de redémarrer l'ordinateur.
Voici le contenu du fichier wificheck.log:

Re : Wifi qui se déconnecte sous Ubuntu 16.04
Bonsoir,
Merci pour cette réponse bien plus rapide que la mienne. Ca fait plaisir de voir une communauté autant réactive, c'est vraiment génial!
J'ai changé le canal sur mon routeur. Le 1 et le 6 ont déjà connu une déconnexion. Je suis en train de tester avec le 11. Je testerais le blocage du module ultérieurement.
Si je répond déjà c'est que la deuxième solution m'interpelle. Qu'est-ce qui dans la sortie
sudo rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: acer-wireless: Wireless LAN
Soft blocked: no
Hard blocked: noamène à penser que le module acer_wmi est responsable du problème? En lisant la documentation sur ce module, je ne comprend pas comment en arriver à cette déduction.

Bonsoir,
Ce sont des conflits de modules, regarde au § 6 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

Re : Wifi qui se déconnecte sous Ubuntu 16.04
Merci pour ces clarifications.
Je vais continuer de tester le canal 11 et si mon wifi se déconnecte encore j'essaierais de blacklister le module acer_wmi.
Si une de ces deux solution reste stable au moins un soirée, je rajouterais un petit "Résolu" au titre de mon post.
