Edit2: o DHCP funciona agora, graças a este post: link
Eu ainda não tenho wlan / wireless.
Na verdade, tenho dois problemas, não tenho certeza se devo fazer dois posts.
Eu atualizei o Ubuntu de 16.04 a 17.04, após a reinicialização, não tive acesso à Internet.
ifconfig -a
mostra minha placa ethernet (nome alterado de eth0 para enp0s31f6), mas não meu wlan.
Quando eu executo sudo dhclient enp0s31f6
no console eu recebo um endereço IP e tenho internet.
Então, minhas perguntas:
1. Como posso fazer o sistema iniciar automaticamente o dhcp e obter um endereço IP?
- Por que minha wlan não aparece e como faço para que ela funcione novamente?
Editar:
ifconfig -a

Isso é depois que eu executei manualmente o sudo dhclient enp0s31f6
, antes que não haja um ip, você também pode ver que o wlan está faltando.

Edit2: Parece ser um problema com o firmware, mas isso realmente não me ajuda: (
