Bonjour,
je viens d'acheter un dongle wifi TP-Link TL-WN821N (V5) pour mon Ubuntu 16.04 LTS. J'ai téléchargé sur le site de TP-Link le pilote recommandé pour cette clé mais je ne suis pas certain que cela convienne puisque mon noyau est d'une version supérieure à celui assuré par TP-Link (
http://www.tp-link.fr/download/TL-WN821N_V5.html#Driver).
Avant de me lancer dans une installation fastidieuse, j'ai besoin d'être rassuré ou aiguillé vers une autre solution. Voici les retours des "commandes WiFi", réalisées avec le dongle branché (même si j'ai l'impression qu'il n'est pas détecté alors qu'il fonctionne très bien sur XP installé en dualboot) :
