Réseau détecté mais impossible de se connecter

liviusbarbatus

J'ai le même problème que VML. Le wifi est actif, les réseaux sont détectés, quand je me connecte à mon réseau perso, ma clé m'est demandé. Mais la connexion ne se fait pas.

[edit modo : conversation scindée de ce topic, pour avoir une conversation propre portant sur un seul problème d’une seule personne. 🙂]

Bonjour,

@liviusbarbatus

Tu as cette solution, proposée par ylag > [RESOLU] Connexion Internet via Ethernet et WIFI Impossible MAJ 18.04

liviusbarbatus

Je viens de passer en 18.04 (lubuntu) mais le problème apparaissait déjà avant cette mise à jour. La solution de ylag ne fonctionne pas pour moi, car j'ai le même NetworkManager.conf que lui.
La commande dsmeg | tail -50 se termine par

wlan0: deauthenticated from ... (Reason: 15=4WAY_HANDSHAKE_TIMEOUT)

J'ai aussi essayé une connexion à FreeWifi, avec le même résultat.

wlan0: deauthenticating from ...(Reason: 3=DEAUTH_LEAVING)

Tu devrais créer une nouvelle discussion pour ton problème, en suivant les indications de Initier une nouvelle discussion

_ _ _

Il faudra fournir, en te servant du Retour utilisable de commande, un [doc]wificheck[/doc] rassemblant les informations > Configuration wifi.

Nota : un fichier wificheck.log est créé dans votre répertoire personnel, collez l'intégralité de son contenu dans votre discussion.

Pour ta carte wifi :

 Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express)

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

§ 2.2 Atheros a écrit 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

Tente la solution proposée par toutafai :

Le 21/01/2014, toutafai a écritA tous ceux qui sont avec de l'ASUS :

Essayer cette modification, facilement "réversible" :
sudo nano /etc/modprobe.d/blacklist.conf
A la fin du fichier, rajouter la ligne suivante :
blacklist asus_nb_wmi
Enregistrer la modification, rebooter et tester si le wifi est ok

PS : Pour annuler la modification, il suffit simplement de supprimer la ligne ajoutée, enregistrer et rebooter

_ _ _

S'assurer d'un chiffrement en WPA2 seul, comme indiqué au § 1 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier.

liviusbarbatus

Je suis désespéré. Aucune des solutions proposées ne fonctionnent. rfkill n'indique aucun blocage.

xubu1957

Tu as deux modules WLAN, la solution de toutafai correspondait à la désactivation d'un module ( § 6-A [Tuto] Pas de Wi-fi ? Eléments importants à vérifier).

_ _ _

Quel est le canal Wifi utilisé ?

liviusbarbatus

Peux-tu m'indiquer quels sont les deux modules dont tu parles ?
J'ai remis en place la solution toutafai, qui ne fonctionne pas.
Je rappelle la fin de dsmeg

Bit Rate=1 Mb/s

La procédure de la Doc > wifi#connexion_lente :

§ 6.5 a écritSi vous voyez Bit Rate=1Mb/s alors tapez :

sudo ifdown wlan0
sudo iwconfig wlan0 rate 54M
sudo ifup wlan0

Enfin, faites "iwconfig" pour vérifier qu'il vous met bien Bit Rate=54Mb/s . Voilà qui devrait aller mieux !

pour que ça reste permanent : Ajoutez dans /etc/rc.local (avant la ligne exit 0)

/etc/rc.local

 ifconfig wlan0 up
 iwconfig wlan0 rate 54M

liviusbarbatus

Je tape

sudo ifdown wlan0

et j'obtiens

Unknown interface wlan0

xubu1957

Fais voir :

ip -c a

_ _ _

Essaye :

sudo service network-manager restart

quand au redémarage, il s'effectue et je l"avais déjà essayé. Mais toujours pas de connexion wifi.

Je ne trouve pas les commandes adaptées pour la version 18.04.

Tu as un retour avec :

sudo iwconfig wlan0 power off

liviusbarbatus

michel@michel-silvia:/etc$ sudo iwconfig wlan0 power off
[sudo] Mot de passe de michel : 
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Operation not supported.

Ce soir, je vais me reposer. Je cale sur ce problème de Wifi. Je voulais amener mon petit portable ASUS PC1025CE en voyage. En absence de wifi, il devient hélas tout à fait inutile pour cet usage.
Ce qui est le plus irritant, c'est de voir que le wifi détecte les réseaux, donc fonctionne partiellement.
