Instale o adaptador de rede sem fio no Centos 7

1

Eu tenho um laptop Acer Aspire e5-575g-53vg com o Centos 7 e um kernel atualizado 4.7.3-1.el7.elrepo.x86_64. A Acer diz que meu adaptador sem fio é um Intel Wireless-AC 7265 (qualquer forma de verificar isso sem ter que desmontar o laptop?), Mas o lspci não está mostrando este dispositivo. Eu fiz o download dos drivers do Linux e colocá-los em / lib / firmware como diz no site, mas não sei o que fazer a seguir.

Eu também tentei seguir estas instruções , mas

nmcli con

retorna

que mostra o dispositivo ausente da nova conexão wlp2s0.

Abaixo está a saída para lspci -v :

Serge me acompanhou e resolveu esse problema.

Primeiro, meu adaptador sem fio é o Qualcomm Atheros Device 0042 (rev 31). Tomando três linhas de este guia ,

git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
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

seguido de uma reinicialização resolveu o problema.

Deve-se observar que, seguindo as etapas acima, o kernel 3.10 pré-empacotado não funciona. Eu tive que atualizar para 4.7 para que funcionasse.
