Deconnexions wifi intempestives
Lorsque je me connecte au réseau wifi, la connection ne dure que quelques secondes puis le réseau disparait des réseaux disponibles et tous les ordinateurs connectés en wifi sont déconnectés du réseau.
J'ai une freebox v6.

Re : Deconnexions wifi intempestives
Bonjour !
Je pense qu'il faut modifier la configuration wifi de ta box.
Je pense qu'elle apparaît dans le scan en premier, et que tu ne diffuses pas le SSID (c'est pour cela qu'elle n'apparaît pas ESSID:"<hidden>")
Il faudrait te connecter sur l'interface d'administration de ta box.
Change le numéro de canal.
Tous les points d'accès a proximité émettent sur le canal 11.
Change donc le canal pour 1, cela devrait beaucoup mieux marcher.
Tu peux aussi cocher diffuser le SSID (ou nom de réseau) cela pourrait simplifier le diagnostic ultérieur.

Re : Deconnexions wifi intempestives
C'est assez compatible avec le problème de canal réseau que je t'ai soumis. Certaines box ont un choix de canal automatique, mais selon mon expérience, cela ne marche pas toujours très bien. Il a suffit que l'une d'entre elle reboote pour que le problème disparaissent.
Si tu relances une commande sudo iwlist wlan0 scanning tu devrais voir les autres canaux. Si le problème se reproduit, la recommandation de changer le numéro de canal reste valide.
