Ubuntu WiFi est extrêmement lent et se déconnecte toutes les quelques minutes
J'ai consulté différents messages pour comprendre pourquoi le Wifi est si lent, mais en vain.
J'ai installé Ubuntu 16.04 juste avant-hier et j'effectue un double démarrage avec Windows 10. Windows 10 me donne une vitesse normale, mais lorsque j'essaie de me connecter via Ubuntu, je ne peux pas obtenir une vitesse supérieure à 40/50 Ko. Je joins les scripts Wireless-info en sortie ci-dessous, et serais heureux de fournir toute autre information nécessaire. Merci.

Vous avez deux pilotes éventuellement en conflit chargés. Faisons une liste noire et voir si cela aide. Depuis le terminal:
Sudo -i
echo "blacklist rtl8192cu" >> /etc/modprobe.d/blacklist.conf
modprobe -r rtl8192cu
exit
Toute amélioration? Cela pourrait prendre un redémarrage.
Maintenant, 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.
