Réseau wi-fi invisible et connexion manuelle impossible
Bonjour,
Je me connectais habituellement sans problème au réseau Wi-Fi de mon lieu de travail (DYNAMO) depuis mon netbook ASUS sous LUBUNTU.
Je viens d'acquérir un DELL XPS 13 et depuis, impossible de trouver ce réseau Wi-Fi et de m'y connecter, même si j'utilise l'option "créer un réseau Wi-Fi" et que j'entre les bons identifiants.
Du coup, je suis obligé de passer par mon téléphone sous Android en partage de connexion (le HIGHWAY 4G retourné en iwconfig), qui lui trouve le réseau sans problème, ainsi que tous mes collègues...
Si vous avez une idée, je suis preneur !
Merci d'avance,
Sébastien

Re : Réseau wi-fi invisible et connexion manuelle impossible
Bonjour
J'ai un problème similaire avec mon dell xps 2015.
Pas de wifi du tout, et pas non plus de sortie casque (je ne sais pas si il y a un lien)
Quand j'essaye d'installer certains programmes qui aideraient, comme alsamixer, voici ma réponse:
"Des erreurs ont été rencontrées pendant l'exécution : oem-audio-hda-daily-lts-quantal-dkms"
aidez moi svp
