Problemas de conectividade Wi-Fi e Ethernet após a atualização para 12.04

Question

Eu atualizei recentemente para o Ubuntu 12.04 a partir de 11.10, e desde então eu não consegui me conectar à Internet, nem usando wifi, nem usando ethernet. Eu tenho lido muitos posts, mas não encontrando uma solução em nenhum. Meu laptop é um HP-G61 de 64 bits, meu cartão Wi-Fi Atheros AR9285 e minha placa ethernet Realtek RTL 8101E / RTL8102E. Antes de atualizar tudo funcionou bem. Eu tentei executar uma configuração de rede manual usando o terminal, mas não funcionou. Alguém tem uma idéia de como eu posso resolver o problema? É possível voltar para o antigo 11,10? Muito obrigado antecipadamente, anexo a saída de alguns comandos

Aqui está um tópico relevante com a solução nos fóruns do Ubuntu .

Em suma: lista negra do módulo incompatível editando

/etc/modprobe.d/blacklist-network

e adicionando a seguinte linha:

r8169.ko

Em seguida, encontre ou crie um driver / módulo r8101 válido, seja no site da Realtek ou daqui

Copie e instale o novo módulo para:

/lib/modules/3.2.0-23-generic-pae/kernel/drivers/net/ethernet/realtek/

Em seguida, digite:

sudo depmod -a
sudo modprobe r8101

Pode ser necessário corrigir o endereço MAC ausente e reiniciar o gerenciador de rede. Use um endereço MAC exclusivo (preferencialmente o original) em vez de < MYMAC > abaixo.

sudo service network-manager stop
sudo ifconfig eth0 down 
sudo ifconfig eth0 hw ether < MYMAC >
sudo ifconfig eth0 up
sudo service network-manager start
