Eu tenho um adaptador de rede sem fio Qualcomm Atheros QCA6174 802.11ac que funciona bem depois de reinicializar o computador, mas se eu desabilitar e reativar o wi-fi através do controle GUI no canto superior direito da tela, ele nunca voltará e devo reiniciar. Eu tenho razões para acreditar que isso é um problema de firmware. Alguma coisa parece errada no seguinte:

Obviamente, há um problema aqui.
O que tentei:
Eu segui as instruções em um post semelhante e re-baixei o firmware ath10k_pci, e fiz toda a coisa "renomear para firmware-5.bin e firmware-4.bin". Isso não funcionou e tenho certeza que fiz corretamente. Fora isso, não sei o que fazer.
EDIT: Acho que uma parte muito importante disso é que o meu Wi-Fi FUNCIONA, somente quando eu faço uma nova inicialização. Assim que desativo meu Wi-Fi através do ícone da GUI na bandeja do sistema, o driver trava e eu preciso reiniciar.
