[RESOLU] Perte de connexion et impossible de retrouver le réseau
Bonjour à tous,
Je viens d'acheter un adaptateur wifi pour ma bécane, un TRENDnet TEW-648ubm.
Au démarrage, pas de problème, la clé est reconnue en direct et j'arrive à me connecter à ma box (Thomson TG784n d'OVH) sans problème. Sauf qu'au bout d'un temps variable, je perds la connexion et impossible de la retrouver sans redémarrer ou enlever puis remettre la clé.
Voici les infos sur la bête:

Merci d'avance si quelqu'un peut m'éclairer sur ce mystère ou me donner une commande permettant de récupérer le signal (comme j'ai besoin rapidement d'un moyen de connexion wifi, je pense échanger la clé contre une Hercules HWGUm-54 si le problème persiste).
Cordialement,
K

Re : [RESOLU] Perte de connexion et impossible de retrouver le réseau
Bonjour
en regardant sur leur site
OS Compatibility List = linux : pas supporté....
par contre tu peux essayer avec le driver realtek

Re : [RESOLU] Perte de connexion et impossible de retrouver le réseau
Merci agil!
J'ai suivi ton conseil, et récupéré le driver, puis suivi la procédure expliquée dans ce fil: http://forum.ubuntu-fr.org/viewtopic.php?id=1170821
Depuis (mais j'ai peu de recul) j'ai l'impression que ça roule (encore aucune déconnexion même avec des transferts importants).
On croise les doigts!
A bientôt,

Re : [RESOLU] Perte de connexion et impossible de retrouver le réseau
Bonjour,
J'attendais effectivement d'être certaine que le problème soit résolu. Manifestement on est passé de quelque chose d'instable à une connexion fiable (sur une journée de test ça semble OK :-) ) donc je passe en résolu.
Cordialement,
K.
