lubuntu14.04安装后无法连接网络,如图！

[风吹我已散]

怎么办？

把下面指令 複製 貼進終端機 執行
1. sudo lshw -numeric -class network
2. sudo ifconfig -a
3. sudo route -nv
4. sudo dhclient -v
把結果直接複製 貼上來

product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10EC:8168]
configuration: ... driver=r8169 ...

1. 目前作用中 驅動 r8169

2. r8169 不是 稱職的驅動 for RTL8111/8168/8411

3. 到這裡 下載合適的驅動

4. 安裝好以後 再執行剛剛那幾個指令 看看結果有何改變
