Connexion wi-fi anormalement faible et instable

Bonjour à tous, ma connexion wi-fi a toujorus été plus ou moins instable mais depuis certain temps ce n'est plus acceptable. Je suis en dual boot Windows 10/ Ubuntu 20.04.5 LTS. La wi-fi fonctionne sans problème sur windows. J'ai désactivé le secure boot. J'ai également modifié le wifi.power-save à 2.
Voici les logs demandé :

As-tu essayé avec les canaux conseillés (au lieu du canal 3) ?

Le 07/03/2018, un expert du wifi sur Ubuntu, chili555 a écrit :

Please check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Veuillez vérifier les paramètres dans le routeur. WPA2-AES est préférable ; pas de mode mixte WPA et WPA2 et certainement pas de TKIP. Deuxièmement, si votre routeur est capable du mode N, vous pouvez avoir une meilleure connectivité avec une largeur de canal de 20 MHz dans la bande 2,4 GHz au lieu de 20/40 MHz automatique, bien que cela puisse affecter  mode N. J'ai aussi plus de chance avec un canal fixe, 1, 6 ou 11, plutôt que la sélection automatique des canaux. Assurez-vous également que le routeur n'est pas configuré pour utiliser uniquement du mode N; Auto B, G et N sont préférés. Après avoir apporté ces modifications, redémarrez le routeur.

Ta Box peut-elle aussi utiliser les fréquences 5 GHz, pour essayer un canal 36 ?

Re : Connexion wi-fi anormalement faible et instable

Je viens de passer au canal 11 et il me semble que c'est mieux mais je me demande si ce sera toujours le cas dans 5 minutes ou 1 heure. C'est un autre problème, ma box a en effet la fréquence 5 ghz mais le réseau wifi n'est pas détecté... Je suis connecté sur Clembox24 qui est en 2.4 ghz et le réseau Clembox5 qui est détectable sur windows et mes autres appareils n'apparait pas.

Pas de notice ou de site d'assistance pour ta Box ?

Re : Connexion wi-fi anormalement faible et instable

Comment le problème pourrait-il venir de la box ? Tous mes autres appareils trouvent le wifi 5ghz. Voilà ça ne marche déjà plus.. De nouveau le même problème, je suis à moins de 0.5 mo/s.

Salut.

Pour info, bien qu'ily ait officiellement 11 canaux Wi-Fi en 2,4 Ghz, seuls les 1, 6 et 11 sont utilisables. En effet, à cause de la "largeur de bande" le 1 déborde jusqu'au 3, donc il le parasite.

langfr-700px-2.4_GHz_Wi-Fi_channels_%28802.11b%2Cg_WLAN%29.svg.png

Autour de cette fréquence centrale le signal est modulé sur une plage de fréquence de 20 MHz à 22 MHz. Chaque canal occupe donc une plage de fréquence de +/-11 MHz autour de sa fréquence centrale
