Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Bonjour à tous,

Après avoir essayer de dépatouiller mon problème de WiFi, je me remets à vous pour me donner de bon conseils.
Il s'agit d'une installation fraîche de Kubuntu 20.04.1 LTS sur un Dell Precision M4700 (même phénomène et symptôme avec une installation de Neon 5.20 sur le même ordinateur).
Avant, cet ordinateur avait Ubuntu-mate 16.04.x LTS sans aucun problème de WiFi.

Le WiFi est instable et semble passer en mode inactif, pour le rendre actif, j'ouvre l'indicateur réseau et survol le nom de mon WiFi ou le laisse l'indicateur épinglé avec la visualisation du débit.
J'ai essayé avec les drivers propriétaire du module WiFi BCM4313 (que j'utilisais avec cet ordinateur sous Ubuntu-mate 16.04 LTS et qui fonctionnait parfaitement) :

sudo apt-get install bcmwl-kernel-source

Mais c'est pire plus de connexion automatique et débit inexistant après connexion, j'ai repurgé le driver avec :

sudo apt-get remove --purge bcmwl-kernel-source

Il semblerait que ma sœur subisse le même problème de WiFi sur un Dell Latitude E5430 depuis qu'elle a fait la mise à jour de Ubuntu-mate 18.04 LTS vers Ubuntu-mate 20.04 LTS (mais son ordinateur est principalement connecté via LAN).

Merci pour votre support,
Seb

Re : Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Bonjour,

Vu :

 BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] 

Pour le chipset 14e4:4727

Essaye :

sudo -i
echo "blacklist b43" >>  /etc/modprobe.d/blacklist.conf

Re : Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Salut,

Merci pour la réponse rapide, mais cela n'a pas résolu le problème.
Voilà, ce que je constate, si je n'ai pas d'activité réseau (internet, courriel, synchro avec mon NAS Synology) pendant  plus de 30 s (variable), c'est comme si le WiFi passait en mode veille et y reste (quelque fois le démon Synology poste un message cloud-drive-ui en veille), impossible d'établir une connexion réseau mais l'indicateur WiFi dans la zone de modification indique que je suis bien connecté à mon WiFi et l'icône indique une réception forte du signal (essayé à 2 m du routeur et à 6 m).
Lorsque, c'est comme cela, je clique sur l'icône WiFi pour ouvrir le panneau réseau de la zone de notification, je constate que je suis bien connecté à mon WiFi mais les indicateurs Up et Down sont à 0 o/s (pas d'activité réseau), puis, je suis à nouveau connecté et je vois les débits up et down s'affoler.

Lorsque, je réveille le PC après une mise en veille, même phénomène, l'indicateur WiFi dit connecté mais pas d'activité réseau...

Par contre, si j'épingle le panneau réseau de la zone de notification, pas de problème d'activité réseau (même en sortant l'ordinateur de veille).

Chose que je viens de remarquer l'indicateur WiFi physique du PC n'est pas allumé alors que le bouton physique est bien en position ON (d'ailleurs en passant de ON à OFF puis à ON, la connexion redevient opérationnelle).

Voilà, le petit résumé des essais et cas de tests que je viens de faire pendant 2 heures.

Re : Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Salut,

Juste pour éviter les quiproquo, je suis au Québec et il y a 6 h de décalage avec la France.

Dans blacklist.conf, j'ai bien à la fin ceci :
blacklist amd76x_edac
blacklist b43
blacklist ssb

Entre deux réunions de travail (merci le télétravail), j'ai continué à investiguer...
1) j'ai désactivé les modules BT, WLAN et WWAN dans le BIOS, redémarrage puis apt-get update, upgrade autoclean et autoremove, redémarrage réactivation du module WLAN
==> j'ai récupéré l'indicateur LED de WiFi en haut du clavier dans tous les cas de fonctionnement.
==> premier démarrage temps qu'il n'y a pas de veille la connexion reste active mais la force du signal et la vitesse de connexion font le yoyo
==> après une sortie de veille, aléatoirement je pers l'activité WiFi comme décris dans les messages précédents

2) réinstallation du paquet "bcmwl-kernel-source"
==> plus de connexion automatique à l'ouverture de session, ni après la veille
==> connexion manuel, mais plus de perte de connexion et la force du signal et la vitesse de connexion reste stable, et cela est comparable au valeur de mon DELL Latitude E6400 sous NEON 5.19 qui a aussi ce driver proprio.

3) suppresison du paquet "bcmwl-kernel-source"
==> premier démarrage temps qu'il n'y a pas de veille la connexion reste active mais la force du signal et la vitesse de connexion font le yoyo
==> après une sortie de veille, aléatoirement je pers l'activité WiFi comme décris dans les messages précédents

Re : Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Salut,

Donc, je viens de faire plusieurs essais et je vais revenir sur ce que j'ai dit hier car le PC est sur batterie alors qu'hier il était sur secteur:
Cas 1) SANS le paquet "bcmwl-kernel-source" et à 6 m du router WiFi sur batterie
- Débit catastrophique de l'ordre de 2 Mbps en Down et 1.5 Mbps en Up
- La force du signal et la vitesse de connexion font le yoyo entre 1 Mbit/s et 74 Mbit/s plusieurs fois par seconde
- L'indicateur physique du WiFi (LED) reste éteint (même après commutation On, Off puis On du bouton physique du WiFi)
- Ce qui est positif, se reconnecte toujours au WiFi au démarrage, à la sortie de veille et à la commutation du bouton physique du WiFi

Cas 2) AVEC le paquet "bcmwl-kernel-source" et à 6 m du router WiFi sur batterie
- Débit similaire à mon DELL Latitude E6400 sous NEON 5.19
- La force du signal et la vitesse de connexion très stable et similaire à mon DELL Latitude E6400 sous NEON 5.19
- L'indicateur physique du WiFi (LED) fonctionne correctement (même après commutation On, Off puis On du bouton physique du WiFi)
- Ce qui est négatif, ne se reconnecte pas automatique au WiFi au démarrage, à la sortie de veille et à la commutation du bouton physique du WiFi malgré que tous les résequx WiFi soient découvert et que sur celui où il doit se connecter soit en première position et bien détecté avec la force du signal qui varie lorsque je me déplace.
J'ai essayé à ce moment là :

sudo service network-manager restart

Je vois bien le gestionnaire réseau se recharger, redécouvrir les WiFi mais toujours pas de reconnexion automatique à mon WiFi.
Dans la boîte de dialogue des paramètres de ce réseau WiFi "Se connecter automatiquement avec priorité" est bien coché avec une priorité à 1

==> Ce que j'en conclus à ce stade:
- Cas 1) je pense qu'il y a quelque chose qui est en relation avec un mode de conservation d'énergie qui suspendrait la carte WiFi ou la ferait passer en mode Low-Power d'où le yoyo signal/vitesse et perte d'activité réseau (de façon très flagrante lorsque le PC est sur batterie).
- Cas 2) le blacklistage B43 et SSB a suprimé l'instabilité de ce cas de figure mais toujours pas de connexion automatique...

==> Donc quel serait pour toi le meilleur angle de résolution :
- Cas 1) SANS le paquet "bcmwl-kernel-source" et régler l'instabilité réseau ?
- Cas 2) AVEC le paquet "bcmwl-kernel-source" et régler la reconnexion automatique ?
Personnellement, mais mes connaissances sont limités sur ce sujet, je préfère creuser le cas 2) car cet ordinateur à toujours bien fonctionné avec le paquet "bcmwl-kernel-source" sous Ubuntu-mate 16.04 LTS.

Ce que j'ai effectué depuis le cas 2)

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-dkms

Redémarrage
Donne un retour au cas 1)

Installation du paquet "broadcom-sta-dkms"

sudo apt-get install broadcom-sta-dkms

Redémarrage
Donne le cas 3) similaire au cas 2) mais avec la vitesse de connexion un peu plus faible:
- Débit légèrement plus faible à mon DELL Latitude E6400 sous NEON 5.19
- La force du signal plus forte et la vitesse de connexion plus faible que le cas 2)
- L'indicateur physique du WiFi (LED) fonctionne correctement (même après commutation On, Off puis On du bouton physique du WiFi)
- Ce qui est négatif, ne se reconnecte pas automatique au WiFi au démarrage, à la sortie de veille et à la commutation du bouton physique du WiFi malgré que tous les réseaux WiFi soient découvert et que sur celui où il doit se connecter soit en première position et bien détecté avec la force du signal qui varie lorsque je me déplace (similaire au cas 2).
- Redémarrage du "Network-manager" lorsque non reconnecté automatiquement donne le même résultat que le cas 2)

Re : Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Pas de problème, je vais creuser encore.

Pour résumer : je me suis remis dans le cas 2), soit : blacklistage de B43 et SSM plus utilisation du paquet "bcmwl-kernel-source" ce qui donne une utilisation du WiFi correct et stable mais reste à résoudre la reconnexion automatique.
Dès que, j'ai du nouveau je compléterai le fil de discussion.

Merci xubu pour ton aide !

Salut xubu,
J'ai été bien occupé ces dernières semaines, je n'ai pas eu le temps de creuser plus que ça.
Aujourd'hui, j'ai pris le temps de regarder les logs dans la configuration du cas 2)
==> Blacklistage de B43 et SSM plus utilisation du paquet "bcmwl-kernel-source" ce qui donne une utilisation du WiFi correct et stable mais sans la reconnexion automatique

qui correspondent au moment où il devrait y avoir la reconnexion automatique, est-ce une piste ?

J'ai aussi remarqué ce message qui est posté toutes les 2-3 secondes dès qu'une connexion WiFi est établi

13/12/2020 13:47	systemd-resolved	Server returned error NXDOMAIN, mitigating potential DNS violation DVE-2018-0001, retrying transaction with reduced feature level UDP.

Merci, pour toute suggestion afin de régler la reconnexion automatique,

Re : Résolu - WiFi instable/inutilisable Kubuntu 20.04.1 LTS

Résolu, j'ai changé la carte WiFi et plus de problème, quand même très bizarre que les problèmes sont intervenus après le passage à Kubuntu 20.04 LTS.
Donc la Broadcom BCM94313HMG2L a été remplacé par une Intel 7260 HMW.

Bonus, j'ai le Bluetooth intégré de la carte Intel qui marche nativement, j'ai retiré la carte Bluetooth Dell...
