Estou executando o Ubuntu 16.04 em um Lenovo IdeaPad Yoga 13, e o computador não consegue se conectar ao Wi-Fi. Nenhuma rede sem fio aparece no menu de conexões. Eu tentei instalar Este driver baseado em Esta resposta , mas não mudou nada. Eu coloquei na blacklist o módulo r8723au de /etc/modprobe.d/blacklist.conf
para desativar o driver instalado anteriormente, mas o wireless ainda não funciona.
EDITAR:
lspci | grep Wireless
e lspci -nnk | grep 0280 -A2
não têm saída, mas a saída de lsusb
contém a placa sem fio:
Bus 001 Device 005: ID 0bda:1724 Realtek Semiconductor Corp. RTL8723AU 802.11n WLAN Adapter
