ralentissement (saturation ?) du Wifi avec le temps

Bonjour,

Depuis quelques temps j'ai un problème qui devient vraiment pénible. Quand j'allume l'ordi tout fonctionne nickel, mais au bout d'un moment internet devient très lent (uniquement sur mon ordi Ubuntu) et je suis obligé de redémarrer l'ordinateur pour que cela revienne à la normale. Comme si le Wifi saturait à l'utilisation. J'utilise Firefox, Chrome et Edge et c'est pareil sur les trois (chaque membre de la famille a son propre navigateur tongue)
J'ai essayé en désactivant et réactivant le wifi ça ne règle pas le problème.

Je suis sous 20.04
et voici mon lspci si ça peut aider

Re : ralentissement (saturation ?) du Wifi avec le temps

Bonjour,

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

Étape 2 : Il ne reste plus qu'à copier le contenu du fichier wificheck.log (et non le fichier wificheck qui est le programme qui a généré le fichier wificheck.log) situé dans le dossier personnel et le copier sur le forum.


Important : Pensez à passer vos sujets en [Résolu] lorsque ceux-ci le sont, au début du titre en cliquant sur Modifier sous le premier message, et un bref récapitulatif de la solution à la fin de celui-ci. Merci.

Re : ralentissement (saturation ?) du Wifi avec le temps

Bonjour,

Vu :

 Invalid misc:197

Il faudrait résoudre les problèmes d'interférences

Re : ralentissement (saturation ?) du Wifi avec le temps

Bonjour,
Je pense qu'il pourrait être utile de vérifier l'encombrement des bandes du réseau wifi afin de sélectionner le canal le moins occupé. Normalement il devrait y avoir dans l'utilitaire de gestion de la box une petite application pour voir ça.
Ensuite, toujours à partir des applis de la box, changer le canal utilisé pour le moins occupé.

NB : ça pourrait du même coup limiterdéplacer les problèmes d'interférence

Re : ralentissement (saturation ?) du Wifi avec le temps

en fait le problème ne vient que de mon pc ubuntu, mes deux autres pc portables windows ont un wifi qui fonctionne bien en permanence (environ 3 à 5Mo/s en DL) et mon macbook télécharge entre 15 à  20Mo/s alors que mon ubuntu ralenti. Je ne dis pas non plus que ça ralenti quand je télécharge comme un malade, la plupart du temps seul mon poste ubuntu tourne, les autres c'est occasionnel. Et comme  j'ai dis, je résous ce problème de ralentissement par un redémarrage du poste, donc si ce n'était qu'un problème d'engorgement je ne vois pas pourquoi un reboot corrigerait le problème.

edit : je viens de vérifier l'encombrement, je suis sur le canal 1 qui est assez libre, visiblement tous les autres wifi autour sont sur le 6

Si c'est un problème de wifi cela ne va pas aider,
En revanche j'utilise cette méthode pour accéder à mes Gdrive, et cela fonctionne bien !

Le problème de cette solution c'est qu'il n'y a pas de synchro avec le pc, donc pas d'accès hors connexion. Bon, dans l'absolu je n'ai pas vraiment besoin de les avoir hors connexion, mais je préfère l'avoir pour le "au cas où".

Bonjour,

21 paquets peuvent être mis à jour

Lance :

sudo apt full-upgrade

Pour purger les résidus de configuration, comme expliqué à la machine à café :

sudo apt purge ~c
