O Google é meu amigo. Agradecemos a fóruns do Ubuntu e ao maravilhoso ArchWiki :
Users with Realtek 8168 8169 8101 8111(C) based NICs (cards / and on-board) may notice an issue where the NIC seems to be disabled on boot and has no Link light. This can usually be found on a dual boot system where Windows is also installed. It seems that using the offical Realtek drivers (dated anything after May 2007) under Windows is the cause. These newer drivers disable the Wake-On-LAN feature by disabling the NIC at Windows shutdown time, where it will remain disabled until the next time Windows boots. You will be able to notice if this issue is affecting you if the Link light remains off until Windows boots up; during Windows shutdown the Link light will switch off. Normal operation should be that the link light is always on as long as the system is on, even during POST. This issue will also affect other operative systems without newer drivers (eg. Live CDs).
Soluções possíveis:
- Reverter / alterar o driver do Windows
- Ativar WOL no driver do Windows
- Driver mais recente do Realtek Linux
- Ativar ROM de inicialização da LAN no BIOS / CMOS
Eu tentei o segundo que funciona. 4º não (MB é um antigo EPoX).
Para ativar WOL WIN + R - > devmgmt.msc
- > clique duas vezes na sua NIC - > Na guia Avançado, defina Ativar / desativar o desligamento como Enabled
. REINICIE!
