Mon Asus Zenbook UX304UA semble avoir des problèmes de connexion aux nouvelles normes wifi. Ce problème est apparu pour la première fois lorsque j'utilisais temporairement le wifi de mon voisin et il est à nouveau constamment instable lorsque je suis connecté au wifi d'une entreprise semi-publique. Ce qui m'intrigue, c'est que mon téléphone n'a aucun problème. De plus, le problème s'aggrave lorsque la batterie tombe en dessous de 25%...
J'ai fait tourner ubuntu 20.04 et j'ai déjà mis à jour la dernière version du BIOS de l'ordinateur portable (UX305UA.302). La sortie de sudo lshw -C network est :
