Plus de connexion à cause de Freewifi ? [résolu]

Bonjour à tous,
Après une nuit en hibernation, mon portable se réveille ce matin incapable d'établir une connexion qui a toujours bien fonctionné. Un redémarrage complet n'y fait rien, me voilà bien démuni...
Ci-dessous les informations de circonstance, merci de votre aide !

Re : Plus de connexion à cause de Freewifi ? [résolu]

Un petit complément : un live-CD de la 8.10 établit sans pbm une connexion, ce n'est donc pas un problème matériel... Mais de là à tout réinstaller pour ce seul hic...
Merci de vos lumières !

Re : Plus de connexion à cause de Freewifi ? [résolu]

J'avance un peu tout seul... Mon diagnostic à l'heure qu'il est : une borne Freewifi sans protection, que je vois pour la première fois dans le quartier, m'enquiquine... Ce qui me semble étrange est surtout le iwconfig qui indique ESSID="FreeWifi" alors que j'ai une livebox. Comment faire en sorte que celle-ci soit pris en compte ?...
Merci !

Re : Plus de connexion à cause de Freewifi ? [résolu]

Problème résolu en ayant changé le canal de la Livebox, le 1 étant manifestement encombré par le nouveau venu FreeWifi...
