Bonsoir à tous,

Je suis sous Debian GNU/Linux 9 (stretch) 64 bits avec Gnome version 3.22.2, et j’utilise Network Manager pour me connecter à Internet.

Depuis quelques semaines, je ne parviens plus à me connecter au WIFI, quel que soit le réseau. J’ai essayé de réinstaller le driver de la carte réseau, de changer de logiciel, de réseau… Je n’ai pas pu résoudre le problème. Je précise que je parviens à me connecter à internet en USB avec mon portable.

Voici quelques détails :

**`lspci -nnd ::0280`**

salut  
ondirait

- soit un pb de mot de passe
- soit une incompatibilité de norme wifi

à ta place j’essaierais une clé wifi usb ; non utilisation de networkmanager mais /etc/network/interfaces ; changement de norme sur ta freebox

et un dmesg |tail -n 30

- quand tu mets en route ton wifi avec networkmanager ( clic droit )
- quant tu fais un service networkmanager restart .
