[Résolu] problème wifi suite déménagement

Bonjour,
J'ai parcouru le forum pour essayer de résoudre mon problème de wifi mais rien n'y fait.
J'ai conservé ma box donc le nom et le mot de passe restent inchangés. J'arrive à me connecter via mon smartphone...
Voici les infos en vous remerciant d'avance si vous avez un peu d'attention à m'accorder : (pour info la commande nm-tool ne fonctionne pas...)

-------
Résumé de la  solution :
1 (mise à jour)

sudo apt update
sudo apt full-upgrade

+ redémarrage

2 (procédure pour la carte Atheros AR9285 => wifi_liste_carte#atheros)
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.
+

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

+ redémarrage

Bonus sur le message #8 :
Si lenteur, vérifier les problèmes d'interférence

Re : [Résolu] problème wifi suite déménagement

Bonjour,

Vu :

4.15.0-54-generic x86_64

Fais les mises à jour :

sudo apt update
sudo apt full-upgrade

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

Re : [Résolu] problème wifi suite déménagement

Merci pour ton aide xubu1957
Malheureusement, les commandes n'ont pas résolu mon problème de connexion wifi. J'ai redémarré l'ordi pour info.
J'ai vérifié une deuxième fois par acquis de conscience, mais ma freebox est bien sur le mode : WPA2 PSK/AES.

Re : [Résolu] problème wifi suite déménagement

Bonjour,

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

Re : [Résolu] problème wifi suite déménagement

Bonne nouvelle :
J'ai changé le canal et copié/collé les 2 commandes.
Après redémarrage, j'ai réussi à me connecter au wifi de la box.

Cependant la connexion est très très lente...
Ça va passer ou il reste une commande à faire pour améliorer le débit ?

Je passe le sujet en [résolu] si tu estimes qu'il n'y a rien à faire de plus.
Encore merci

Re : [Résolu] problème wifi suite déménagement

Bonjour,

 Tx excessive retries:139  Invalid misc:3093

Pour des problèmes d'interférences :

Dans >  wifi-too-much-invalid-misc-how-to-fix-it

Wifi  "Invalid misc", comment le réparer?
Voici quelques résultats:

root@debian:/home/love# iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:"SITI_Broadband-06E6-G"  
      ...
          Tx excessive retries:0  Invalid misc:202   Missed beacon:0

J'ai remarqué que la valeur augmente avec le temps et que mon wifi reste connecté, mais Internet arrête de fonctionner.
     
Cela ressemble à un problème typique d'interférence wifi. Essayez de localiser l'appareil causant le problème et, lorsque vous le faites, supprimez cette question car elle serait hors sujet. Il suffit simplement de désactiver la plupart des équipements électroniques et de faire attention à ce qui change lorsque les problèmes commencent, peut généralement résoudre 90% de ceux-ci.

Dans > linux.die.net/man/8/iwconfig

Tx excessive retries
Number of packets that the hardware failed to deliver. Most MAC protocols will retry the packet a number of times before giving up.
Nombre de paquets que le matériel n' a pas pu livrer. La plupart des protocoles MAC vont réessayer le paquet plusieurs fois avant d'abandonner.

Invalid misc
Other packets lost in relation with specific wireless operations.
Autres paquets perdus en relation avec des opérations sans fil spécifiques.
