Também estou tendo problemas com o controlador Ethernet RTL8111. Não está funcionando no Ubuntu x64.
Este é o meu cartão:

05:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 06)
Subsystem: Gigabyte Technology Co., Ltd Motherboard [1458:e000]
Kernel driver in use: r8168
Eu testei com as seguintes versões do amd64:
Mint 16 | Kernel 3.11 | r8169 & r8168 not working
Debian 7.2 | Kernel 3.2 | r8169 & r8168 not working
Ubuntu 13.10 | Kernel 3.11 | r8169 & r8168 not working
Ubuntu 12.04.3 | Kernel 3.8 | r8169 & r8168 not working
Ubuntu 12.04.2 | Kernel 3.5 | r8169 & r8168 not working
Ubuntu 12.04.0 | Kernel 3.2 | r8169 & r8168 not working
Ubuntu 11.10 | Kernel 3.0 | r8169 & r8168 not working
Debian 6.0.7 | Kernel 2.6 | r8169 working fine, r8168 working fine
Ubuntu 10.04.4 | Kernel 2.6 | r8169 working with known problems, r8168 working fine
Smos1.2 (Debian) | Kernel 2.6 | r8169 working with known problems, r8168 working fine
Conclusão: A rev 06 do RTL8111 / 8168 não está funcionando acima do AMD64 Kernel 2.6
Regressão:
Eu gostaria de oferecer uma pequena doação de BTC como 0,03 BTC para uma solução de trabalho porque eu preciso dessa correção o mais cedo possível.
Veja uma lista de infos e registros:

Eu tive o mesmo problema por anos agora e com todas as atualizações que envolvem um kernel, ele irá reiniciar com a rede desconectada, eu tenho isso abaixo. Desligue a máquina, puxe o plugue, segure o botão de energia por um segundo ou dois e tente novamente. Se isso falhar, exclua /etc/udev/rules.d/70-persistent-net.rules e reinicie normalmente.
O Windows estava muito bem em se conectar à minha ethernet e adquirir o endereço IP e o acesso à Internet. O Ubuntu também estava se conectando bem no começo. Depois de um tempo, quando eu estava inicializando no Ubuntu eu não tinha nenhuma rede, mesmo que eu ainda tivesse no Windows.
Eu decidi ver o que acontece com os leds piscando na porta lan, porque quando eu estava perguntando ifconfig eth0 não tinha IP e nenhuma atividade de pacote.
A solução para o problema (que ocorreu estranhamente apenas no Ubuntu) foi mexer o cabo um pouco e forçá-lo um pouco para trás.
