Wifi não funciona no Ubuntu 16.04 ACER Aspire E14

Question

Eu tenho tido problemas com wifi desde 14.04 ... Eu atualizei para 16.04 e tentei sudo apt-get update && upgrade mas ele não funcionou ... Eu sou muito novo no Linux, então eu não sou capaz de descobrir o problema. Aqui estão algumas informações do sistema que talvez sejam úteis.

Parece que você precisa de firmware! Por favor, tente, com uma conexão de internet ativa:

sudo apt-get update
sudo apt-get install linux-firmware

Reinicie. Está funcionando? Se não, por favor verifique:

sudo dpkg -s linux-firmware

Esperamos ver que a versão instalada é 1.157.13. Se não, tente:

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.13_all.deb
sudo dpkg -i linux-firmware*.deb

Reinicie. Está funcionando?

EDIT: Eu suspeito que o download foi de alguma forma corrompido. Vamos tentar de novo:

cd /tmp
rm -rf linux-firmware*
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157.13_all.deb
ls -al

Esperamos que o tamanho seja 44364698. Se sim, vamos instalá-lo:

sudo dpkg -i linux-firmware_1.157.13_all.deb

Se o tamanho do pacote baixado for diferente, pare e poste o tamanho.

Por favor, poste quaisquer erros ou avisos.
