Bonjour à tous,
J'ai épluché et re-épluché les forums et les sites comme j'ai l'habitude de faire, mais cette fois je fais appel à vous directement car je suis perdu!
J'ai un vieil ordi Optiplex 760 et souhaite une connexion sans fil. J'ai donc acheté une clef wi-fi "TP-Link TL-WN823N", qui est compatible Linux.
Le problème est que mon ordi ne détecte rien, ni la clef, ni le wi-fi. Uniquement la connexion filaire grâce à laquelle je vous écris.
Voici le résultat des commandes :

Voilà! Désolé pour le pavé mais j'ai lu que c'était la marche à suivre pour des problèmes de wi-fi.
Toute aide est la bienvenue! Je vous en remercie par avance
Modération : merci à l'avenir d'utiliser les balises code (explications ici).
