Pode ser DNS.

Dá um ping assim:

ping -c4 8.8.8.8

Você instalou o firmware-nonfree?

Já que aparentemente tudo está OK em termos de configuração, talvez seja problema de driver.

Instale o firmware-nonfree:

apt install firmware-nonfree

Se não encontrar o pacote, deve ser pq vc não habilitou o repositório nonfree no Debian.

Sabe como habilitar?

Talvez tenha digitado errado?

Veja, o pacote existe:

https://packages.debian.org/stretch/all/firmware-linux-nonfree/download

Talvez eu tenha colocado o nome errado. Confira aí.

O "sources" está com "nonfree". OK.

Então nesse link que eu passei, entre e baixe o pacote ".deb".

Instale com:

dpkg -i [nome do pacote]
