Ubuntu 16.04 wifi Intel 7265 lent / déconnexion
Hé, j’ai un nouvel Asus Zenbook avec une carte wifi Intel 7265 et, en quelques minutes, la connexion Internet devient très lente/ne fonctionne pas du tout. J'ai le dernier pilote du site Intel lwifi. Est-ce que quelqu'un sait ce qui ne va pas? Voici le message de dmesg:

Je possède et utilise avec succès deux périphériques sans fil Intel. J'ai perfectionné quelques techniques depuis plusieurs années et des milliers de messages sur le forum.
Tout d’abord, vérifiez les paramètres du routeur. WPA2-AES est préféré; pas tous WPA et WPA2 mode mixte et certainement pas TKIP. Deuxièmement, si votre routeur est capable de N vitesses, vous pouvez bénéficier d’une meilleure connectivité avec une largeur de canal de 20 MHz dans la bande des 2,4 GHz au lieu de la fréquence automatique 20/40 MHz, bien que cela puisse affecter les vitesses de N. J'ai aussi plus de chance avec un canal fixe, que ce soit 1, 6 ou 11, plutôt que la sélection automatique du canal. Assurez-vous également que le routeur n'est pas configuré pour utiliser uniquement N vitesses; Auto B, G et N est préféré. Après avoir apporté ces modifications, redémarrez le routeur.
Ensuite, je recommande que votre domaine de réglementation soit défini explicitement. Vérifiez le vôtre:
Sudo iw reg get
Si vous obtenez 00, il s'agit d'un paramètre unique. Trouvez le vôtre ici: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Réglez-le ensuite temporairement:
Sudo iw reg set IS
Bien sûr, remplacez votre code de pays si ce n'est l'Islande. Définissez-le en permanence:
gksudo gedit /etc/default/crda
Utilisez nano ou kate ou leafpad si vous n'avez pas l'éditeur de texte gedit.
Changer la dernière ligne pour lire:
REGDOMAIN=IS
Relisez attentivement, enregistrez et fermez l'éditeur de texte.
Ensuite, je définirais IPv6 sur Ignore dans Network Manager: http://docs.fedoraproject.org/en-US/...pv6-ignore.png Cet exemple concerne Ethernet, mais vous veux sans fil.
Enfin, je vous suggère de mettre à jour le firmware.
cd /lib/firmware
Sudo wget https://github.com/OpenELEC/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265D-21.ucode
Redémarrez et dites-nous comment ça marche.
