[RÉSOLU]lenteur de connexion internet (ethernet & wifi) sur Asus X550C

tsoham

Bonsoir,
J'utilise un portable Asus depuis 2013, d'abord vendu sous Windows, je l'ai passé sous Ubuntu.
L'internet est lent, je m'en suis particulièrement rendu compte par conférence vidéo : sur mon portable Asus, connexion instable y compris en liaison éthernet, images saccadées arrivant à nos interlocuteurs. En utilisant le nouveau portable Asus de mon épouse, sous Windows, lenteur également, y compris en éthernet. En utilisant l'Ipad de ma fille, en wifi, aucun problème, connexion rapide !
J'en arrive à envisager de passer à un Imac, si vous savez m'orienter pour améliorer peut-être la prise en charge de ma carte wifi, vous sauverez mon vieux portable...
Merci par avance.

Bonjour,

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

Bonjour,

Pour ta carte wifi :

Qualcomm Atheros AR9485 Wireless Network Adapter [168c:0032] (rev 01)

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

tsoham

Merci beaucoup pour cette piste ! Je tenterai le réglage sur canal <10 ce soir et vous tiendrai au courant !

tsoham

Bonsoir,
Je suis passé en canal 9, pas de changement sensible, peut-être est-ce visible dans le wificheck que je viens de faire, je le colle ici.
Merci pour les pistes données.

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

tsoham

j'ai voulu tenter la solution de toutafal ; la ligne blacklist asus_nb_wmi était déjà inscrite en fin de fichier blacklist.conf.

Comment savoir si les modifications apportées sont efficaces ? je vois l'indication de 195 Mbit/s, est-ce un niveau très bas ? quel indicateur permettra de savoir que la connexion est améliorée ?

dans mon usage habituel, et depuis un changement de box (Freebox Révolution) et paramétrage par un technicien en ligne, mon internet sur mon PC portable est stable est suffisamment rapide. J'ai vu pourtant une énorme différence en téléconférence, entre mon PC et l'Ipad de ma fille. J'ai demain une téléconférence pour un entretien professionnel, je prévois d'utiliser plutôt l'Ipad de ma fille que mon PC... :-(

J'avais piqué une commande donnée par toutafai dans > [Résolu]Carte Wi-Fi ignorée - AR9485 - Packard Bell LV44HC, mais je ne sais pas que faire des retours.

tsoham

je viens de faire des essais sur speedtest.net : rien de choquant entre mon PC sous Ubuntu et la tablette Ipad de ma fille.

PC/ubuntu = 6,85 en download, 0,81 en upload (carte wifi 2.4G)
Ipad = 9,37 et 0,85 (carte 2.4G)
Ipad = 10,52 et 0,89 (carte 5G)

Les écarts ne me semblent pas si énormes pour expliquer qu'une conférence téléphonique soit hâchée, pleine de coupure sur mon PC, et fluide sur l'Ipad.

Pour les nettoyages :

Le 20/02/2017, moko138 a écritPour supprimer tous ces fichiers de configuration devenus sans objets et marqués "rc", et uniquement ces fichiers, exécute :

dpkg -l | awk '/^rc/{print $2}' | xargs -r sudo dpkg -P

sudo apt clean && snap list --all | awk 'BEGIN {print "#! /bin/sh\n"} ; /désactivé|disabled/ {print "snap remove "$1" --revision "$3"\n"} ; END {print "exit 0"}' > script && chmod +x script && ./script && rm script && echo && snap list --all && echo && df -Th | grep -Ev "tmpfs|squashfs"

Pour VLC :

Le 13/12/2018, cqfd93 a écritBingo !

Je te suggère de supprimer ce snap, de faire les mises à jour et d'installer à la place la version des dépôts (donne les 4 retours) :

sudo snap remove vlc
sudo apt update
sudo apt full-upgrade
sudo apt install vlc
