Fala, galera. Há dias eu tenho fritado a cabeça tentando resolver este problemão: meu notebook ASUS X451CA vem com a placa interna Qualcomm Atheros AR9485, que simplesmente não é identificada pelo sistema. Na verdade, às vezes reinicio a máquina e o Ubuntu ESPONTANEAMENTE reconhece a placa. Depois, o problema torna a aparecer. Procurei em mil fóruns, escrevi intermináveis linhas de código no terminal, e NADA resolve. Seria problema no hardware? Peço socorro à comunidade. Obrigado.

Seguem as saídas de alguns comandos úteis:

iwconfig



lo        no wireless extensions.



enp3s0f2  no wireless extensions.
