Problème de WIFI sur fresh install 14.04 - Dell XPS L701X

Bonjour à tous.

J'ai installé Ubuntu sur plusieurs PC, tout s'est bien passé, sauf pour ce DELL XPS.

En ethernet pas de soucis, tout à donc été installé et mis à jour, mais en WIFI, rien. (même en débranchant le cable)

Voici les infos pour ce PC, merci d'avance pour les solutions que vous pourriez m'apporter.

Re : Problème de WIFI sur fresh install 14.04 - Dell XPS L701X

Merci pour la réponse. J'ai donc testé.

Au moment ou j'ai lancé le shutdown, des messages ont défilés sans arret. Au bout de 1 mn ou 2 j'ai éteind
Au redemarrage, system not found, plus d'ubuntu.

J'ai redemarré avec une live pour retomber sur ma session, plusieurs test de redemarrage, ok.

J'ai retenté, au shutdown, hop, rebelotte, les lignes qui défilent. J'ai désactivé le wifi via la touche de fonction, et hop, ca a arrété de défiler, et shutdown normal.

Toujours pas de WIFI
