tests avec une carte RTL8723BE

Nuliel · Le 24/08/2020, à 13:12

Bonjour,
Ce fil a pour but de faire des tests sur un pc avec une carte rtl7823be. Ce pc fonctionne sur xubuntu 18.04.1. Je n'ai pour l'instant jamais démonté ce pc, je ne sais donc pas si les deux antennes sont branchées.
Voici quelques retours utiles:

Le pc est à plus de 5m de la box, avec le pilote de Larry Finger, ça fonctionne impec.

Maintenant, on installe le HWE et on voit ce que ça donne (j'ai une clé wifi si besoin)

Bref, ça a l'air de fonctionner. Je ne sais pas ce qui peut faire que ça fonctionne sur ce pc et pas sur un autre.
A noter que le bluetooth a les mêmes problèmes que le wifi.

Bonjour,

Pourquoi un chiffrement WPA1 WPA2 ?

Le chiffrement mixte est à éviter, dixit les experts :

Le 18/11/2012, toutafai a écrit :

Bonsoir,
Les connexions par câble sont généralement reconnu et fonctionnelle de suite à 100%...pour le wifi comme certaines autres box font, il faut vérifier que le cryptage/chiffrement qu'elle fait soit standard. Un truc louche que font beaucoup de box par défaut c'est à la fois du WPA1 et à la fois du WP2, ce qui peut être la cause de problème, donc a configurer soit en WPA1 TKIP, soit (et mieux) en WPA2 AES (enregistrer les changements et rebooter la box).

_ _ _

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.

C'est vrai, je n'y ai pas pensé (comme ça a toujours fonctionné avec cette box j'ai jamais pensé à changer ça)

Nuliel · Le 24/08/2020, à 13:45

En voulant résoudre le problème de touchpad, j'ai cassé le HWE, donc je l'ai supprimé et je suis revenu à l'état initial

Nuliel · Le 25/08/2020, à 10:37

Je me demande si le problème rencontré par d'autres personnes sur ce forum avec cette carte ne serait pas dû à l'absence d'une antenne
Qu'en pensez vous?

Bonjour,

En ayant aussi désactivé le secure-boot !

Nuliel · Le 25/08/2020, à 11:03

Hum, faudrait vérifier mais je pense que le pilote du noyau est signé, donc c'est pas impossible qu'on puisse garder le secure boot activé

Tu avais vu cette réponse de Pilot6 ? > askubuntu.com/questions/1254210/realtek-rtl8723be-wireless-card-does-not-work-in-ubuntu18-04

Nuliel · Le 25/08/2020, à 14:21

Non, je ne l'avais pas vu. En gros il conseille de retirer toute installation faite sur des noyaux précédents pour pouvoir utiliser le pilote inclus dans le noyau.
Sur un noyau 5.4, le pilote de Larry Finger n'avait pas compilé, donc il n'a pas non plus été installé

> Wifi non disponible

Pour un noyau 4.15 en version 16.04, il faut proposer quel pilote ?

Nuliel · Le 25/08/2020, à 14:35

Celui de larry finger fonctionne (je peux le fournir), je n'ai pas testé le pilote du noyau avec la branche 4.15 mais il est possible qu'il fonctionne

Bonjour à Tous,

Actuellement je suis sur une 18.04.1 avec ce module WiFi et le pilote de L. Finger. Ca fonctionne, néanmoins les performances RF restent limitées (ça se traduit par une portée limitée).

Sur une 16.04, ça fonctionnait correctement avec le pilote du noyau jusqu'à ce qu'arrive le noyau 4.15 (donc avec les noyaux 4.4, 4.10 et 4.13 en ce qui me concerne).

Je n'ai pas de configuration spécifique pour le pilote (pas de fichier /etc/modprobe.d/rtl8723be.conf). Par défaut, c'est l'antenne 1 qui est utilisée. Quand je passe sur l'antenne 2, je passe d'un signal de -24 dBm à -78 dBm (donné avec la commande iwconfig), la box étant à proximité immédiate du PC. Une perte de 53 dB, c'est une puissance de signal divisée par 200 000, autrement dit je ne reçois plus rien...

Nuliel · Le 26/08/2020, à 10:43

Oui, il y a toujours une antenne qui déconne avec cette carte, et ça peut devenir problématique lorsqu'une seule a été installé
Je pense qu'il est important d'utiliser un fichier /etc/modprobe.d/rtl8723be.conf pour stocker le choix d'une antenne.
Par défaut, je pense que l'antenne peut changer à l'utilisation.

Bonjour,

Pour info, un fil récent > Realtek RTL8723BE Wireless card Does not work in Ubuntu18.04, dans les intervenants chili555 et jeremy31

Je colle les retours du #13 :
Here are the results of Wifi and Mobile tethering
