Isso soa como um problema comum ao atualizar 11.04, mas estou tendo problemas para encontrar uma solução comum e que funcione para mim.
Acabei de aplicar atualizações por meio do gerenciador de atualização e agora minha conexão de rede com fio está inativa. Eu sei que as configurações de rede do Ubuntu é o problema, porque eu tenho um dual-boot com o Win 7 e minha rede / internet está bem no Win 7. Eu não sei muito sobre redes, então o que posso fazer para solucionar esse problema ?
Eu posso escolher uma versão antiga do grub, 2.6.38-8 ao invés de 2.6.38-11 e isso não resolve o problema.

Recentemente, tive um problema semelhante. Minha rede sem fio funcionaria, mas eu queria usar a rede com fio, mas não importava o quanto eu desligasse minha rede sem fio, ela não se conectaria por fio.
Então eu tentei sudo service network-manager stop seguido de sudo dhclient3 eth0 e eu consegui trabalhar.
Acho que o seu seria eth1 em vez de eth0 .
