Problema de rede no Linux Mint 19.1 Cinnamon (Conexão com fio)

Estou com um problema que percebi quando precisei usar internet via cabo, percebi que mesmo estando com o cabo conectado e funcionando, o sistema não reconhece.

Nas opções de rede não exibe a opção “Com fio”.
Já testei no Windows e está funcionando normal, a dificuldade é só no Linux Mint.

Tente desconectar do wifi e conectar via cabo. Se conseguir rode ip r && ifconfig -a
Se não conseguir rode ip r && dhclient -v enp7s0
Depois faça dmesg | grep enp7s0
Copie a saída dos comandos

O dhclient precisava de root p ser rodado , mas parece q nem conexao ao gateway vc tem. Tente levantar a interface
sudo ifconfig -v enp7s0 up
se der certo rode
ip r && sudo dhclient -v enp7s0
Se tiver ethtool rode ethtool enp7s0 (não lembro se precisa de root)
