Carte realtek RTL8111G problèmes wifi avec ubuntu 16.04

yoann54

Bonjour à tous,

Je rencontre un problème un peu étrange sur mon ordinateur (gigabyte GB-BXi5-4570R) avec ma connexion wifi, elle fonctionne un certain moment puis s'arrête, parfois je fais un network-manager restart et ça repart mais parfois même pas. Quelqu'un a t'il ce problème avec la carte realtek 8111G ?

Voici le résultat de la commande mentionné en tête du forum :

Bonjour,

La carte wifi:

RTL8821AE 802.11ac PCIe Wireless Network Adapter

Tu peux essayer cette commande:

echo "options rtl8821ae fwlps=0" | sudo tee /etc/modprobe.d/rtl8821ae.conf

d'après le post # 5 de ce fil : forum.ubuntu-fr.org/viewtopic.php?id=1970541

yoann54

Merci xubu pour ta réponse qui fonctionne bien, ce code évite que la carte se mette en veille mais je me demande pourquoi le driver générique ne le fait pas...je vois sur le site de realtek qu'il n'y a pas de driver pour le kernel 4 le problème est peut être là. Merci en tout cas pour l'aide apporté !

xubu1957

Bonjour,

Plusieurs membres du forum, en version 16.04, ont amélioré le wifi en désactivant le secure boot.

Documentation : [doc]desactiver_secure_boot[/doc]

La version est en phase de maturité, on verra fin juillet, lors de la sortie de la 16.04.1, si les améliorations ressortent !

yoann54

J'ai fait cela aussi mais cela n'a rien changer dans mon cas, je ne sais pas si je dois mettre le sujet en résolu car parfois j'ai encore de drôles de ralentissements même si le wifi ne se déconnecte plus. Néanmoins je suis conscient que la 16.04 est en pleine phase de maturation donc je vais être patient et je reviendrais apporter mon expérience à ce fil dans les prochaines semaines... Merci Xubu !!!!

Bonjour,

Tu n'as pas essayé de changer de canal Wifi ?

La documentation : [doc]wifi_optimisation[/doc]

yoann54

Bonjour,

Au final j'ai de nouveaux les coupures assez fréquentes d'internet, et ce n'est pas un problème de canal wifi apparemment, j'ai supprimé le fichier que j'avais crée à la lecture du post #2. Il m'avait pourtant semblé que ça avait amélioré les choses. Quelqu'un a t'il une mauvaise expérience de ce type avec la carte RTL8821AE 802.11ac PCIe Wireless Network Adapter ?
