RTL8188CE se déconnecte et ne se reconnecte pas sur Lenovo E520
J'ai installé le pilote RTL8188CE sur le site Web de realtek. Il se connectera après un nouveau démarrage et fonctionnera bien. Mais à un moment donné, il se déconnecte (généralement dans les 15 minutes) et ne se reconnecte plus. Il reste bloqué sur "Obtention de l'adresse IP ..." jusqu'à ce qu'il ne parvienne pas à se connecter entièrement et ne se connecte pas sans redémarrage.
sortie dmesg de la déconnexion manuelle et de la tentative de reconnexion:

La façon de corriger cela est de recompiler le noyau en raison de la mise à jour/mise à niveau, il n'a pas été récupéré.
