我打ifconfig -a
出現的訊息

我是選擇這個安裝的

安裝且與其他作業系統並存
(Install alongside other operating systems)


與W7作業系統共存

你的 eth0 的 140.124.32.116 網址
這是 台北科技大學/機械系 區網 IPv4
所以你的 網卡應該沒問題

我剛有改IP位址 address gateway netmask 但是還是不能上網耶

請你提供兩個檔案 幫你看看
sudo gedit /etc/network/interfaces
sudo gedit /etc/NetworkManager/nm-system-settings.conf

另外 你要上網際網路 需要帳號與密碼嗎？
（不必列出來 你只要說 Yes or No)

NO
是區域網路的
他會給固定IP

方便把這個貼上來嗎？
sudo gedit /etc/network/interfaces
sudo gedit /etc/NetworkManager/nm-system-settings.conf
另外
再增加一個
route -n

你這兩個檔案的內容完全不對
（可能你用 wubi 安裝 wubi 是把全部 ubuntu 壓縮在 windows 的檔案中 但是 這個檔案 壞掉了！）
把它檔案內容全部刪除
把我下面列的 copy 然後貼上去

sudo gedit /etc/network/interfaces
auto lo
iface lo inet loopback
<save>

sudo gedit /etc/NetworkManager/nm-system-settings.conf
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
<save>

重開機
看看 桌面右上方 有沒有出現一個 NetworkManager 面板程式 (nm-applet)

可以變成一個檔案我直接覆蓋他嗎?

還有可以留下加我的MSN:jim1988611@hotmail.com
這樣比較好跟你聊
謝謝

如果你有不方便公開的資料
可以 e-mail 給我 poloshiao@hotmail.com
但是 要填個連結 以免我對不起來
