Eu passei por inúmeros tutoriais e perguntas semelhantes na tentativa de resolver esse problema, mas ainda não consigo fazer o Wi-Fi funcionar, então decidi postar uma nova pergunta.

Eu iniciei meu computador Windows com o Ubuntu 14.04 porque meu professor precisava que eu fosse compatível com o laboratório. Na minha partição do windows, o wifi funciona. No Linux, não funciona de todo. Eu tentei sudo-apt obter instalar muitos backports, e nenhum deles funcionou. Houve uma resposta aqui que quase resolvi meu problema, mas tentei fazer o comando sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin e ele não conseguiu encontrar os arquivos depois de fazer todos os outros passos.

Este post foi muito útil, mas não resolveu meus problemas quando passei pelas etapas.

Aqui está minha saída de um monte de consultas de linha de comando. Eu sou um novo usuário Linux e estou tão perdido. Qualquer ajuda seria muito apreciada!

Você precisa instalar linux-firmware de xenial . Tem esse firmware.

Executar 

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.12_all.deb
sudo dpkg -i linux-firmware*
