De repente, nenhum serviço de WIFI e de rede está inativo

1

Eu instalei o Centos 7 64bit no meu laptop Lenovo e o KDE por um tempo, tudo foi ótimo! Ontem à noite eu estava tentando fazer Dolphin mostrar miniaturas de vídeo e toke algum tempo, mas eu consegui fazê-lo, infelizmente, quando eu reiniciei o laptop não havia wi-fi! Eu atualizei o sistema (sudo yum update) e instalei alguns pacotes para o ffmpeg mas nada mais e agora (rede) o serviço está inoperante e não pode ser iniciado Além disso, quando eu tentei "nmtui" não havia conexão wi-fi!

Aqui estão alguns resultados dos comandos que achei que podem ajudar a entender

# lspci -nnk | grep -i net -A2
