Le WiFi (r8712u) ne fonctionne qu'après avoir utilisé rmmod & modprobe
Ma connexion Wi-Fi ne fonctionne pas après la connexion. Je n'ai aucune idée de la raison pour laquelle elle commence à fonctionner après avoir effectué manuellement une analyse rmmod && modprobe. Je suppose qu'il y a quelque chose qui ne va pas dans la commande lors du démarrage.
Ci-dessous deux extraits de mon dmesg. Le premier est au démarrage normal. Le second appartient à mon étape manuelle rmmod/modprobe.
Avez-vous une idée de ce que je peux faire pour résoudre ce problème?

Vous exécutez Ubuntu 16.04 qui n’a pas encore été complètement testé et débogué et n’est donc pas prêt pour la publication. Je crois que la version proposée de Network Manager contient un bogue. Je ne sais pas s'il existe un moyen d'installer une version antérieure de NM dans 16.04. https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1489154
En attendant, je vous suggère de faire:
gksudo gedit /etc/rc.local
Utilisez nano ou kate ou leafpad si vous n’avez pas l’éditeur de texte gedit. Changez le fichier pour lire:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sleep 3
service network-manager restart
exit 0
Relisez attentivement, enregistrez et fermez l'éditeur de texte.
Redémarrer. Des améliorations?
