Bonjour, je viens d'installer Ubuntu 18.04.1 sur un Asus Vivobook S410UA-EB724T sans problème particulier si ce n'est que le wifi est lent. C'est d'autant plus impactant qu'il n'y a pas de port Ethernet et qu'il faudrait que je me procure un adaptateur ethernet-USB.
La carte est une Qualcomm Atheros QCA9377 802.11ac.
Je pense que c'est un problème de Bitrate bloqué à 1 comme décrit
ici. Néanmoins je n'arrive pas à corriger le bitrate avec les commandes préconisées: avec la commande ifdown mon interface n'est pas reconnue
~$ sudo ifdown wlp2s0
Unknown interface wlp2s0
et le fichier /etc/rc.local est vide... Comment puis-je augmenter le bitrate?
Merci d'avance.
Voici le résultat des commandes requises (testé en point d'accès wifi sur smartphone - en 4G+, mais je ne pense pas que ça change quelque chose)
