Bonjour,
Je viens d'installer UBUNTU 18.04.3 sur un PC neuf ASUS TUF Gaming 505DT-AL298 livré sans OS. Tout fonctionne sauf qu'il n'y a pas de WI-FI. Dans les paramètres est affiché "Aucun adaptateur Wi-Fi trouvé".
J'ai beau tenter des commandes que je trouve sur les forums, pas de changement.
Quelqu'un peut-il m'aider SVP ?
Merci d'avance
Philippe
