Ubuntu 14.10 Déconnnections wifi

Bonjour,

Alors voila, de temps en temps ma wifi se déconnecte toutes seul du modéme auquel elle est reliée, ce n'est pas régulier, je rester connecter 2h  avant que sa ne coupe où 10min, ... Lors de la déconnexion, le routeur n'est plus visible dans la liste des réseaux wifi (pourtant toujours accessibles par d'autres équipements), pour le récupérer je désactive le réseau puis je le réactive et la il réapparaît dans la liste.

Re : Ubuntu 14.10 Déconnnections wifi

Bonjour,

changer ton chiffrement/cryptage pour soit que du WPA1 TKIP, soit que du WPA2 AES (ne pas oublier d'enregistrer les changments

puis tester si c'est mieux

Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).
