求大神帮忙，我的ubuntu14.04无法连接有线网络，可以上无线。

之前装过12.04版的，可以上网。可是换成4.04就上不了有线了。刚刚还按照http://forum.ubuntu.org.cn/viewtopic.php?f=116&t=463646这个帖子，9楼的方法，装了驱动，却显示第一张图的情况，之后连有线网络wired connection 1都不显示了在右上角的图标里。下面贴上各种代码的结果。
uname -a
lspci
sudo lshw -C network
ifconfig
ping 192.168.1.1 -c 4
tail /var/log/syslog -n 20
1. sudo ls -al /etc/resolv.conf
2. sudo cat /etc/resolv.conf

1. 把 無線網卡 關閉
或 從右上方 連線圖示 把 無線連線設定 自動連線 打勾取消
2. 重開機
3. 把下面指令 複製 貼進終端機 執行
3-1. sudo lshw -numeric -class network
3-2. sudo ifconfig -a
3-3. sudo route -nv
3-4. sudo rfkill list all
3-5. sudo dhclient -v
把結果直接複製 貼上來 (不必擷圖)
