Estou executando o Ubuntu 16.04 no Lenovo E530. Meu gerenciador de rede desconecta a conexão com fio após alguns segundos. Wifi funciona bem. Como isso pode ser corrigido?

Minhas placas de rede: 

03:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)
0c:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 07)

Atualização # 1

Depois de configurar o endereço IP estático, conecte o cabo e execute o comando 

sudo ethtool enp12s0

O resultado é:

Instale outro driver pelo fornecedor. Executar 

sudo apt install r8168-dkms

e reinicie.
