problème de connection wifi sur un reseau en particulier.

bonjour tout le monde,

je suis actuelement en deplacement pour le boulot dans un airbnb où il y a une freebox à laquelle je n'ai pas accés.

je precise tout de suite que la clé de securité est la bonne car je peux me connecter à ce reseau avec mon téléphone android.
mais quand j'essaye avec mon laptop et son installation fraiche de lubuntu 18.10 (10 jours) il a l'air de se connecter puis de se deconnecter tout de suite.
une notification me dit [connexion perdue plus connecté a 802-11- wirless 'FREEBOX_STEPHANIE-36'.]
je me suis connecter jusqu'a lors sans problème à ma live box, la box de bouygue chez ma mère, une box d'un operateur suisse à genève ainsi que des reseaux ouverts de lieu publiques. j'écris ces lignes grace à la connexion de mon tel en point d'acces mobile.

j'ai du mal a comprendre la plus part de ce que j'ai pu lire dans mes recherche alors un petit eclaircissement ne ferait pas de mal.
et voilà le resultat des commandes :

Re : problème de connection wifi sur un reseau en particulier.

Bonjour,

Pour ta carte :

Network controller [0280]: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)

Essaye la procédure donnée pour la carte Atheros AR9285 dans la Doc wifi_liste_carte#atheros

Les cartes WIFI Atheros fonctionnent plus ou moins facilement sous GNU/Linux Ubuntu au gré des versions. Un pilote unique est utilisé pour tous les modèles, le module ath5k ou ath9k. Parfois, ce pilote ne fonctionne que partiellement et des réglages/optimisations sont nécessaires selon les modèles de cartes.

En cas de lenteur, dans l'interface de configuration de votre routeur, vérifiez le canal utilisé : s'il est en mode "automatique", tentez d'attribuer un canal manuel inférieur à 10. ou essayez la commande :

echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.conf

En cas de difficultés persistantes on peut essayer de faire charger le pilote au démarrage avec la commande :

echo ath9k | sudo tee -a /etc/modules

Re : problème de connection wifi sur un reseau en particulier.

salut et merci xubu1957

j'ai realisé la première commande tenté de me connecter a la freebox puis réalisé la seconde ligne de commande et redemaré.
il n'ya pas de changement pour ce qui est de mon problème.

j'ai executé les lignes de commande mais ignore comment verifier si le canal utilisé est mode automatique.

Re : problème de connection wifi sur un reseau en particulier.

merci, donc ça dit ça pour moi :

~$ nmcli dev wifi
IN-USE  SSID                        MODE   CHAN  RATE      SIGNAL  BARS  SECURITY  
*       white block                 Infra  8     65 Mo/s   100     ▂▄▆█  WPA2      
        FREEBOX_STEPHANIE_36        Infra  12    270 Mo/s  72      ▂▄▆_  WPA1      

je ne sais pas si ça veut dire que c'est en automatique mais le cannal de la freebox est au dessus de 10.
quelqu'un serait comment lui attribuer un canal inferieur à dix comme préconniser plus haut.

Re : problème de connection wifi sur un reseau en particulier.

Il faut choisir le canal (tester avec le 1 ou le 6), en accédant à la configuration de la Freebox comme dans cette image > freebox

> lafibre.info/wifi/quel-canal-wi-fi-choisir-pour-optimiser-son-debit

Il faut aussi mettre un seul chiffrement WPA2, comme indiqué au § 1 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

Re : problème de connection wifi sur un reseau en particulier.

bon bas comme je disait plus haut je n'ai pas aces à la box alors je vais pas pouvoir tester.
mais je change d'operateur pour free ce mois a mon domicile alors , si j'ai un probleme avec ma box je reviendrait ici  et je l'espere je marquerai ce poste comme résolu.

merci encore pour toute les explications.
