Bonjour à tous!
Besoin d'une petite aide pour faire fonctionner la wifi 🙂
Voila ce qu'il se passe : ayant une carte RTL8822BE, j'ai installé le pilote rtlwifi-new pour qu'il compile avec mon noyau. Maintenant Ubuntu détecte bien ma carte et peut activer le wifi, il affiche les réseaux détectés, mais quand j'essaie de me connecter à l'un deux cela échoue et je perds tous les réseaux, même en réactivant la wifi. Je suis sur un Asus Vivobook S405UA-BV502T, le Secure Boot a été désactivé suivant les manipulations trouvées sur Internet.
Voici mon wificheck :

Aussi quelques détails peut-être utiles : voici le retour de la commande modprobe rtl8822be :
florian@chaillol:~$ sudo modprobe rtl8822be
modprobe: ERROR: could not insert 'rtl8822be': Exec format error
De plus certaines erreurs se présentent quand j'éteins l'ordinateur concernant le module r8822be.
Merci d'avance pour votre aide ! 😃
