Obrigado.
Tem como você conseguir um adaptador WiFi USB emprestado, e ver se funciona em sua máquina? Isso abriria algumas possibilidades pra gente.
Continuo intrigado com o comportamento da sua máquina. Ela consegue pegar IP no DHCP, mas não consegue trafegar...
Não deveria haver dificuldade de conexão com esse adaptador RTL8111/8168/8411. Ele é conhecido, estável, eficiente. Se eu estivesse aí, localmente, faria alguns testes mais profundos, tipo, verificar se há tráfego na camada 2, se o protocolo ARP está funcionando, se a máquina consegue trafegar em IPv6, se há algum firewall ativo...
Aliás... um teste me veio à cabeça: podemos ver se há registro de tráfego na máquina. Execute o comando "ifconfig enp5s0" duas vezes, com intervalo de 1 minuto, e observe se há mudança nos contadores ("pacotes RX:xxxx erros:xxxx descartados:xxxx excesso:xxxx quadro:xxxx / Pacotes TX:xxxx erros:xxxx descartados:xxxx excesso:xxxx portadora:xxxx").
Me dê também a saída dos comandos abaixo.
grep enp5s0 /var/log/syslog | tail -50
dmesg | egrep -i "enp5s0|eth0|r8169"
Vou ver se consigo um adaptador WiFi.
Enquanto isso posto os resultados:
