[Résolu] WiFi instable sous Ubuntu 13.04, carte Realtek RTL8188E
Bonjour,
Après avoir finalement réussi à installer Ubuntu 13.04 en dual boot avec Windows 8, c'est maintenant le WiFi qui fait des siennes...
Ma carte wi-fi est une Realtek Semiconductor Co., Ltd. Device 8179 (rev 01) (d'après Ubuntu), une Realtek RTL8188E Wireless LAN 802.11n PCI-E NIC (d'après W8)
Au départ ma carte n'était pas du tout reconnue, en cherchant un peu j'ai d'abord suivi les instructions de ce topic. Ma carte est à présent reconnue, Ubuntu détecte bien des réseaux wi-fi, mais la connexion est très instable : le signal oscille entre médiocre et excellent toutes les 10 secondes, si j'arrive à me connecter à un hotpsot et m'identifier, ça marche bien pendant quelques instants et après plus rien... Parfois je n'arrive même pas à me connecter à la page de login du hotspot...
Quelques recherches Google plus tard, j'ai vu que mettre à jour le kernel pouvait améliorer la prise en charge de la carte. Je suis passé du 3.8.0 au 3.11 (dernière version stable), ce qui n'a pas apporté d'amélioration significative.
J'ai ensuite essayé d'installer les drivers compat-wireless. J'ai essayé ceux du kernel 3.8.3, ce qui fait que ma carte n'est de nouveau plus reconnue sur le kernel 3.8.0. Aucun changement sur le 3.11.
Là je ne vois vraiment pas quoi faire d'autre, et par peur de faire une autre bourde je préfère demander de l'aide ici. Merci d'avance pour vos réponses.

Re : [Résolu] WiFi instable sous Ubuntu 13.04, carte Realtek RTL8188E
J'ai résolu le problème... Seul.
Je suis passé de la 13.04 vers la 13.10 (en repartant de zéro). Ma carte est reconnue et je n'ai pas eu de pilote supplémentaire à installer, le wi-fi est stable.

Re : [Résolu] WiFi instable sous Ubuntu 13.04, carte Realtek RTL8188E
J'ai la 12.04.3 LTS et pour moi le Wifi n'est toujours pas reconnu.
En revanche elle l'est avec la 14.04 Alpha 1.
J'ai bien trouvé une solution ici mais je ne l'ai pas encore testé.
[Edit] Je confirme que passer de la 12.04.3 LTS à la version 13.10, résoud le problème (voir ici).
