把下面指令複製貼進終端機執行
0. uname -a
1. sudo lspci -knn
2. sudo lshw -numeric -class network
3. sudo ifconfig -a
4. sudo route -nv
5. sudo dhclient -v
6. sudo cat /etc/network/interfaces
7. sudo ls -al /etc/resolv.conf
8. sudo cat /run/resolvconf/resolv.conf

1. 有線網卡被關閉 ?

NetworkManager is not running.

2. NetworkManager 沒啟動 ?
2-1. sudo service network-manager restart

还是 @poloshiao 厉害，一眼就看出问题可能不在 mentohust 上
I217-LM，不会又是那个经典问题吧。如果是双系统，需要关闭网络唤醒 (WoL, Wake-on-LAN)

I217-LM + e1000e 这个组合在双系统下容易出现此类问题
前几天刚出现一例 viewtopic.php?f=116&t=473460
主板的某些功能会使网卡无法彻底断电，使得关机时设置无法重置，从而使Windows 驱动和 Linux 驱动的设置相互影响。

vickycq 写了：双系统网卡设置相互影响的问题，有用户报告关闭主板的网络唤醒功能 (WoL, Wake-on-LAN) 可缓解。

poloshiao 写了： 3. 雙系統或多重系統開機
最好把所有關機還耗用電源的設定全部排除
否則問題可能一大堆

LaoAnchor 写了：的确是双系统网卡设置相互影响的问题，在windows和主板上关闭网络唤醒功能后，回到UBUNTU有线联网功能就正常了。

需要在 BIOS 和 Windows 驱动中都设置关闭。包括网络唤醒、PCI-E唤醒和 PXE boot 等等等等

一开始是忘了开启网卡，现在开了以后，就是这样的了。还有你说的你的 DHCP Server IPv4 網址是多少，指的是什么？我的电脑是动态IP。不知道这个。。。在帮我看下吧。谢谢拉

poloshiao · #8

我的电脑是动态IP。

1. DHCP 就是动态 IP
DHCP Server IPv4 就是分配給你动态 IP 的那個伺服器 (通常是 router)

2. 如果不確定
sudo dhclient -v
把結果複製貼上來
如果正常一般會顯示出 DHCP Server IPv4

sudo service network-manager restart
stop: Unknown instance:

3. 顯示你的 network-manager 並沒有開機即自動啟動
3-1. ubuntu 預設由 network-manager 管理上網
一般預設應該是開機即自動啟動
意思是除非是你改變了預設否則開機不自動啟動不正常
sudo dpkg -l | grep network-manager
把結果直接複製貼上來

我的电脑从装了这个系统就没有用过，所以应该不是我改了预设，如果改了，那要怎么改回来呢？

1. 你還不確定 Dhcp Server (路由器) IPv4 網址嗎
1-1. 請提供路由器品牌及型號

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10 (xid=0xa18bd908)

2. 你發出的 dhcp 連線請求沒有獲得 Dhcp Server 的回應
2-1. 可能原因很多
要偵查出問題的來源需要耐心也需要運氣
可能是硬件原因也可能是軟件原因

3. 試試分段檢查
3-1. 先檢查你的本機 (localhost) 到 eth0 有線網卡是否可以溝通
/etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet DHCP

3-2. 暫時改為
/etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto eth0
# iface eth0 inet DHCP
iface eth0 inet static
address 192.168.0.11
netmask 255.255.255.255

3-2-1. 然後
sudo /etc/init.d/networking start
或
sudo /etc/init.d/networking restart
然後
sudo ping -c 3 192.168.0.11
把結果複製貼上來
3-2-2. 上面
sudo /etc/init.d/networking start
或
sudo /etc/init.d/networking restart
如果有錯誤訊息請複製貼上來

tangchuanjiang · #12

DHCP IPV4的地址是在Editing Eth0net connection1/IPV4 Setting/下面有个routes..里面查看吗？我进去，里面好像什么也没有。
还有3-2那个，暂时更改，我要输入什么指令，才能更改为你写的那个蓝色字体的样子？不是很会。。

poloshiao · #13

还有3-2那个，暂时更改，我要输入什么指令

如果你是使用 gedit
1. 第一次先安裝 gksu 套件 (來自 universe 套件庫)
2. 按下 alt + F2
輸入 gksudo gedit /etc/network/interfaces
修改後儲存

DHCP IPV4的地址是在Editing Eth0net connection1/IPV4 Setting/下面有个routes..里面查看吗？

3. 在 routes 設定的是 gateway 不一定是 DHCP IP 也可能就是 DHCP IP
3-1. 通常是 196.168.1.1 或 196.168.0.1 (但不是絕對)
查看你的路由器使用說明書看看有沒有
3-2. 如果你設定 iface eth0 inet dhcp
一般不需要指定 DHCP IPV4 的 IP
dhclient 相關指令會自動搜尋

iface eth0 inet DHCP

3-3. 應該是
iface eth0 inet dhcp
3-3-1. 注意在 Linux 大部分大小寫是不一樣的不要混洨了
3-3-2. 詳細參閱
http://unix.stackexchange.com/questions ... ces-syntax
Good detailed explanation of /etc/network/interfaces syntax?
使用 dhcp 搜尋

tangchuanjiang · #14

3-2-1. 然後
sudo /etc/init.d/networking start
或
sudo /etc/init.d/networking restart
然後
sudo ping -c 3 192.168.0.11
把結果複製貼上來

我的路由器是FAST FS24，看了别人说的，好像是192.168.1.1。
你让我输入的ping -c 3 192.168.0.11 后面两个1中间有空格吗？

1. 因為你使用 sudo 所以才出現許多錯誤訊息
1-1. 使用按下 ctrl + alt + F2
輸入 gksudo gedit /etc/network/interfaces
才不會出現錯誤訊息
1-2. 第一次使用 gksudo 需要先安裝 gksu 套件 (來自 universe 套件庫)

sudo /etc/init.d/networking start

1-3. 沒有出現任何文字回應 ?
不正常
1-4. 試試先 1-4-1 再 1-4-2
1-4-1. sudo service networking start
或
sudo service networking restart

你让我输入的ping -c 3 192.168.0.11 后面两个1中间有空格吗？

1-5. 不是两个1
是 10 11 12 的 11
1-5-1. 這個 192.168.0.11 單純是設定你的有線網卡 eth0 網址跟路由器無關

我的路由器是FAST FS24，看了别人说的，好像是192.168.1.1

2. gksudo gedit /etc/network/interfaces
改回
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.11
netmask 255.255.255.0
gateway 192.168.1.1
2-1. 然後
2-1-1. sudo service networking start
或
sudo service networking restart
2-1-2. sudo service network-manager start
或
sudo service network-manager restart
有任何文字回應複製貼上來
2-1-3. sudo ifconfig eth0
把結果複製貼上來
2-2. 如果以上都成功
2-2-1. ping -c 3 192.168.1.x # 其中的 x 以 2-1-3 顯示出來的 eth0 IP 取代正常的話是 11
2-2-1. ping -c 3 192.168.1.1
把結果複製貼上來
