升級到 13.04 後，我無法進行有線連接（無線網路正常運作）。我檢查了連接設置，它應該會自動連接。
ifconfig 給出：

對我有用的唯一解決方案（我在與以前版本類似的問題中發現）是將以下幾行添加到 /etc/network/interfaces 中。
auto eth0
iface eth0 inet dhcp
但每當我在沒有有線連接的情況下啟動時，我都會遇到網路配置問題，並且必須等待很長時間才能啟動系統。
我知道問題出在我的 e1000e 驅動程式（正確嗎？），但我不太確定我能做些什麼。我很感激任何建議。
答案1
嘗試這個
echo on | sudo tee /sys/class/net/eth0/device/power/control
這絕對應該解決整個問題...完成後，退出 sudo 並拔出，然後再次插入以太網電纜
