Wireless continue de se déconnecter toutes les 5 minutes
J'ai un nouveau Dell XPS 15 sous Ubuntu 17.10. Mon réseau sans fil continue de se déconnecter toutes les cinq minutes. Je dois donc le déconnecter et le reconnecter manuellement.
C'est la sortie de lspci -knn | grep Net -A3.

S'il vous plaît aidez-moi avec cette question ennuyeuse.
Comme je ne peux pas commenter, j'écris une réponse.
Je suis à peu près sûr qu'il s'agit d'un doublon de WiFi instable après la mise à jour de 17.1 .
La solution consiste à mettre à niveau le microprogramme à partir du référentiel géré par Qualcomm à l’adresse https://github.com/kvalo/ath10k-firmware .
Je voudrais désactiver la gestion de l'alimentation wifi et voir comment cela fonctionne
Sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
systemctl restart network-manager.service
