Comprei o dongle USB ASUS AC51 para melhorar o alcance e a velocidade do WiFi do meu portátil (o wifi onboard tem um desempenho fraco). Tudo funciona no Win10, mas não consigo configurá-lo adequadamente no Ubuntu 16.10 com o kernel 4.8.0-26-generic .
Quando eu conecto meu dongle, recebo isso em dmesg :

Eu tenho o módulo do mediatek 7610 instalado:
$ lsmod | grep mt7610u_sta
mt7610u_sta 892928 0

iwconfig mostra-me a interface adicional ra0 , mas ifconfig não mostra.
Você tem alguma ideia de como corrigir isso?
