Connexion wi-fi instable

Teamblast

Haaaaa mince mince mince j'suis bête! C'est que quand je veux relancer la connexion je désactive le wi-fi et je le réactive. Et lorsque J'ai écrit ce que tu m'as proposé je n'avais pas fait attention, et le wi-fi était désactivé... Du coup j'ai refait la manip' mais rien a changé. J'avoue avoir vaguement l'impression que les connexions durent plus longtemps mais je suis toujours obligée de me reconnecter à un moment.

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 :

Tu es sur un canal 11.

Essaies aussi de changer de canal vers un 1 ou un 6 .

et ayant cette remarque à l'esprit :

Le 26/11/2015, inbox a écritIl y a aussi les composants wifi un peu anciens qui ne supporte que les 4/5 premiers canaux. Pour d'autres, ce sont les 10 premiers.

(edit) sinon essayer le PPA comme dans [Résolu] Wifi instable RTL8821ae (perte rapide de connection)

Je me suis mise sur le canal 1, et j'ai installé sans problèmes le driver. Mais l'instabilité perdure :/

Bonjour,

La Doc freeboxv6_boosterwifi indique :

Si vous avez choisi un channel de 1 à 7 : ne pas choisir 40Mhz inférieure.

C'est toujours instable ?

Teamblast

Oui... :/ Un bon indicateur que j'ai est le site d'échecs en ligne lichess.org où je ne peux pas faire une partie entière sans être déconnectée. Étrangement sur Youtube par exemple ça ne se ressent pas, je peux regarder beaucoup de vidéos à la suite sans problèmes. Mais tout ça c'est avec ma box, et là où je travaille, ma connexion wi-fi est là très instable.

Teamblast a écrit...et là où je travaille, ma connexion wi-fi est là très instable.

Si tu peux, tu vérifieras, sur ton lieu de travail.

nmcli dev wifi

Au boulot, si la Box ou le routeur n'est pas en WPA2 , ce sera difficile.
