[Résolu] Trop de déconnexions wifi depuis installation Ubuntu 12.04
Bonjour
Lorsque je me trouve dans la pièce où se trouve la boite freebox, wifi fonctionne (affichage plein sur le signal).
Mais, si je m'éloigne, j'ai des déconnexions intempestives avec wifi après installation ubuntu 12.04 lts sur mon packard bell easynote mfg (via freebox).
Auparavant, wifi marchait même avec éloignement, avec la version ubuntu 10.04 lts.
Mes connaissances sont basiques. Si quelqu'un peu m'aider à résoudre ce problème wifi, ce serait sympa.

Ok, voici l'ensemble des codes sous balises bleues ci-dessus..
Donc voilà le problème : je dois me placer à côté de la freebox pour avoir un signal wifi sinon si je m'éloigne, j'ai des déconnexions intempestives avec wifi après installation ubuntu 12.04 lts sur mon packard bell easynote mfg (via freebox). Auparavant, wifi marchait même avec éloignement, avec la version ubuntu 10.04 lts. L'autre portable Mac n'a aucun problème de connexion (signal Airport 100%, et navigation web rapide). Donc, c'est bien un problème de configuration ubuntu 12.04
Mes connaissances sont basiques. Si quelqu'un peu m'aider à résoudre ce problème wifi, ce serait sympa...
Merci par avance 
Cordialement

Re : [Résolu] Trop de déconnexions wifi depuis installation Ubuntu 12.04
Bon...J'ai un grand moment de solitude....Personne pour m'aider ?
En attendant, j'ai cherché sur internet...la carte wifi serait-elle désactivée ?
car je constate sur la ligne rfkill list :
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Ai-je raison ?
comment changer la première ligne (mettre 1: devant au lieu de 0:), c'est peut-être la solution...?
Si quelqu'un pouvait m'aider?
Merci

Re : [Résolu] Trop de déconnexions wifi depuis installation Ubuntu 12.04
Bonjour
je ne vais pas être d'une grande utilité mais sur le PC la touche Wifi = FN + X (suivant pc) est activée ?
sinon j'ai vu cette commande (pour activé le wifi))
sudo rfkill unblock all POUR METTRE LES RETOURS DU "TERMINAL" voir les explications sur ce post

Re : [Résolu] Trop de déconnexions wifi depuis installation Ubuntu 12.04
Merci alca94, sur mon pc, à côté du bouton allume, il y a un bouton qui ressemble à un radar (qui est allumé), lorsqu'il est éteint le signal wifi est à zéro.
ensuite, j'ai effectué
sudo rfkill unblock allet rien ne change, même si j'ai rebooté
Même problème : déconnexions intempestives, je dois me rapprocher de la freebox pour obtenir un signal à 100%, ça ne m'arrange pas.
Qui a une solution ?

Re : [Résolu] Trop de déconnexions wifi depuis installation Ubuntu 12.04
Bonjour,
Je ne pense pas que la piste de rfkill était bonne : ce qui compte c'est qu'il n'y ait pas de bloquage logiciel ou software.
Il y a énormément d'antennes à vue dans votre configuration. Aucune d'entre elles n'utilisent le canal 1. Modifier la configuration de votre box pour utiliser le canal 1, et refaites le test : cela devrait permettre d'améliorer la portée. (La bande de fréquence du canal 1 est indépendante des canaux 6 et 13 qui sont massivement utilisés autour de vous). Pour ce faire, il faut vous connecter sur l'interface d'administration de votre box.

Re : [Résolu] Trop de déconnexions wifi depuis installation Ubuntu 12.04
Bonjour,
Merci NicoZic56 car j'ai effectivement changé le canal, je suis sur le 1 et depuis cela fonctionne impeccable !
