Bonjour.
J'ai un problème similaire - voire identique - donc je me permets d'intervenir sur ce fil. J'ai la même carte wifi sur un portable MSI. J'ai cru comprendre à la lecture de ce forum que mon problème de wifi instable venait du driver de la carte que j'ai donc tenté d'upgrader avec cette même procédure :
sudo apt-get install -y git build-essential
sudo git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new/
make
sudo make install
sudo rmmod rtl8723ae
sudo echo "options rtl8723ae msi=1" > /etc/modprobe.d/rtl8723ae.conf
Après redémarrage, le wifi fait planter l'ordi - méchamment.
J'ai appliqué la solution de paul_39th_2k8 en désactivant dans le bios la fonction intel speedstep mais au lieu d'un plantage immédiat, la connexion wifi semble effectuée sur network-manager alors que le navigateur n'accède à aucune page. Et après, ça plante encore, je ne peux plus éteindre la machine sans passer par un redémarrage clavier.
Par ailleurs, c'est peut-être anodin, mais j'ai l'ensemble des messages de démarrage qui s'affichent en mode console entre le Grub et le lancement du GUI, alors qu'il n'y avait quasiment rien avant.
J'ajoute les résultats de diagnostic au cas où. Merci d'avance.
