tangning89

bonjour
je commence avec mon pc environ 2009 sous Ubuntu 9.10 ,et maintenant j'ai utilisé toujours Ubuntu LTS .Mais, depuis quand je suis sous Ubuntu 12.04 ou 14.04 mon vitesse de wi-fi, est plus en plus mal ,il commence à diminuer et de temps en temps , il est hors ligne ou déconnecter tout seul!
maintenant je suis sous Ubuntu 16.04, presque comme tout le monde qui ont les problèmes sur wi-fi ,après que j'ai supprimé :le "ath10k"

sudo rm -r /lib/firmware/ath10k

le wifi fonctionne normalement

quelqu'un peut m'aider

Pour ta carte wifi:

une discussion récente : https://forum.ubuntu-fr.org/viewtopic.php?id=1994059 qui n'apporte pas une réponse claire !

As tu la possibilité de désactiver le secure boot ?
Méthode conseillée en version 16.04 pour l'activation du wifi.

Mercie à votre réponse. J'ai monté moi même le PC. Est-ce que ce secure boot existe aussi dans mon PC?

Salut,

Regarde ça : http://images.frandroid.com/wp-content/uploads/2014/09/wi-fi-e1410530330209-1000x710.jpg

La wifi, c'est la connexion entre l'ordinateur et le routeur (généralement une box plutôt qu'un routeur indépendant). Mais si tu vas sur le net, il y a aussi la connexion entre le routeur et le réseau internet (qui va du routeur au site sur lequel tu veux te connecter). Le débit global est évidemment celui de la partie la plus lente, et c'est rarement la ligne wifi...
