L'activation de la connexion a échoué
Bonjour,
j'ai quelques soucis avec ma carte réseau depuis 2 jours. Celle-ci se déconnecte parfois du réseau, la wifi saute. Et là je ne peux plus du tout me connecter. J'ai le même problème sous windows 10 (je suis sur Ubuntu 18.04).
Je vous joins le wificheck :

Fais tes mises à jour :
sudo apt updatesudo apt full-upgradeet redémarre l'ordi.

Re : L'activation de la connexion a échoué
Merci pour ta réponse !
Malheureusement cela ne résout pas le problème : la connexion reste très aléatoire que ce soit sur Windows ou Ubuntu. La plupart du temps j'ai un message d'erreur l'activation de la connexion réseau a échoué et équivalent si Windows. Et ça peut importe le WiFi...

Re : L'activation de la connexion a échoué
Bonjour,
Sur Windows, tu as essayé de mettre à jour le pilote Wi-Fi ?

Re : L'activation de la connexion a échoué
Oui ma carte réseau est à jour sur Windows. Ce que je ne comprends pas tellement c'est le côté aléatoire. En redémarrant simplement l'ordinateur cela résout parfois ce problème..

Re : L'activation de la connexion a échoué
Pensez-vous qu'il soit possible étant donné que j'ai le problème sur les deux os que ce soit le module WiFi qui rentre en conflit ? J'ai l'impression que lorsque je change d'os, si je désactive le WiFi avant, celui ci sera fonctionnel sur le nouvel os

Re : L'activation de la connexion a échoué
J'avais conservé cette réponse :
Le 10/01/2017, Bougron a écrit :
Bonjour.
(...)
- Désactiver le démarrage rapide de windows. Sous windows
powercfg /hibernate off
- Ne jamais stopper windows avec la fonctionnalité ARRETER mais toujours avec la fonctionnalité REDEMARRER lorsqu'on est susceptible de lancer ubuntu et d'utiliser des périphériques utilisés par windows : Les partitions NTFS, le WIFI et probablement le bluetooth.
Ce fonctionnement est lié au démarrage rapide de windows qui verrouille (via le bios) les périphériques afin d'être sur de les retrouver à l'identique lors de son démarrage qui ne refait pas les séquences d'initialisation.
- De stopper windows avec ARRETER que lorsqu'on est absolument sur que le prochain démarrage qu'on choisira de faire sera windows.(...)
