[résolu] Probleme de connexion Wifi
Newbie du forum et d'Ubuntu,
De retour chez mes parents pour les vacances, je n'arrive pas a me connecter au wifi (freebox) de la maison... (alors que chez moi, j'y arrive tres bien)
le reseau est détecté mais la connexion ne se fait pas...
peut etre que j'ai touché sans faire exprès à quelque chose...

Re : [résolu] Probleme de connexion Wifi
Bonsoir,
Es-tu connecté en filaire quand tu essaies de te connecter en Wi-Fi ?

Pour éviter de perdre vos données, utilisez des formats ouverts (cf. www.formats-ouverts.org).
Regardez l'utilisation moyenne de votre processeur et pensez à BOINC.

Re : [résolu] Probleme de connexion Wifi
euh en général non, le filaire n'est pas tres pratique ^^'
edit : probleme réglé, prise d'une inspiration pas très intelligente,
j'ai simplement mis le reseau en mode visible > connection directement OK (trouvez l'erreur)
pis je l'ai remis en mode invisible et l'a détecté <3
pas tres logique, mais bon, probleme résolu en tout cas
