Il apparatt que le module chargé par le kernel 5.0.0.21 est différent de celui du kernel 5.0.0.20
J'ai essayé de faire sudo rmmod rtwpci mais je n'arrive a recuperer la connexion.
Merci pour ces commandes qui m'ont permis d'identifier l'origine du problème.
Si vous connaissez le moyen de changer de module en repassant sur r8822be
je suis preneur,
Bien cordialement,
