[Résolu] wifi instable

Bonjour à tous,

J'utilise KUbuntu 14.04 (KDE5 est plus une blague qu'un OS) sur un MacBookPro 11,3. Mon wifi est terriblement instable: j'arrive à me connecter, mais la connexion est  très saccadée, parfois ça fonce puis tout à coup ça s'arrête, plus rien ne se passe pendant un temps, puis ça recommence. Souvent je suis déconnecté. C'est très aléatoire. De mon téléphone (Android) ainsi que d'un autre MacBookPro sous MacOS, aucun problème. J'ai mis ici le résultat de `wireless-info`. Quelqu'un peut-il m'aider avec ça? Merci infiniment!

Martin

Modifier, le chiffrement de la Box , comme le conseille toutafai dans de nombreuses discussions :

Ta box utilise un double chiffrement (à la fois du wpa1 et du wpa2), c'est certainement la source de ton problème.
Connecte toi sur l'interface d'administration de ta box et change moi cela pour
  soit que du wpa1 TKIP,
  soit que du wpa2 AES
(ne pas oublier d'enregistrer les changements sur ta box),
Une fois que ce sera fait, tu ne devrais plus avoir de déconnexions

Ton noyau :

est celui de la version 15.04, il faudrait passer sur une version 14.04.5 LTS !
Rajout - avec les noyaux 4.4 de la version 16.04 Xenial voir la Doc : passer_a_la_derniere_etape_de_version_lts

Bonjour,

Tu es sur le canal 2 :

Re : [Résolu] wifi instable

Bonjour,

Merci encore pour l'aide. Malheureusement il semble que les problèmes de connexion persistent, malgré le fait que je sois en WPA2 uniquement, et sur le canal 11. Et comme toujours ça fonctionne parfaitement depuis Android, MacOS. Voici le wireless-info. Une idée? Merci encore.

Martin

Re : [Résolu] wifi instable

Bonjour,

Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

Est il possible de désactiver le secure-boot  ?

Voir le § 2  [Tuto] Pas de Wi-fi ? Eléments importants à vérifier et documentation à la suite.

Merci à moko138 pour avoir rapatrié les données et pour info : c'est le script du forum anglophone :

Bonjour,

Copie ces 3 lignes (qui ne font qu'une commande) :

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

Ouvre un terminal (avec ctrl-alt-t) et colle la commande, appuis sur Entrée et tape ton mot de passe.

Quand c'est fini, donne le contenu du fichier dont le chemin t'est donné par une ligne comme :

Re : [Résolu] wifi instable

Bonjour,
Et merci encore pour l'aide. Malheureusement les problèmes de connexion persistent. Une chose que je ne comprends pas: si c'est un problème d'interférence entre les channels, pourquoi est-ce que cela pose problème uniquement sur mon macbook ubuntu? Mon téléphone android, mon autre macbook sous macos, etc, tous fonctionnent sans problème. Merci pour les éclaircissements!
Martin

Bonjour,

Il faut régler les canaux en 2.4 et 5 Ghz.

Incroyable! J'ai activé le réseau 5GHz, je me connecte dessus et ça a l'air de fonctionner à merveille! Ça n'explique toujours pas pourquoi j'ai des problèmes d'interférences uniquement avec mon macbook pro ubuntu, mais en tout cas ça marche! Merci puissance infinie! : ) Martin
