Re : [Résolu] Wifi bas débit RTL8723BE

Bonjour, j'ai finalement installer ubuntu UNITY 18.04 sur le site http://ubuntu-fr.org, mais le même problème apparais. Les commande précédaient indiquer: 
sudo modprobe -r rtl8723be
sudo modprobe rtl8723be ant_sel=2
N'ont plus aucun effet. Cependant cette commande:
iwlist scan | egrep -i 'ssid|quality'
me retourne:
enp0s20u3  Interface doesn't support scanning.

enp2s0    Interface doesn't support scanning.

lo        Interface doesn't support scanning.

Re : [Résolu] Wifi bas débit RTL8723BE

Bonjour,

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

Nota : un fichier wificheck.log est créé dans votre répertoire personnel, collez l'intégralité de son contenu dans votre discussion.

Re : [Résolu] Wifi bas débit RTL8723BE

Bonjour,

Quand tu as installé ta version 18.04, tu as désactivé le secure-boot ?

Donne le retour de :

sudo modprobe rtl8723be
