ubuntu15.10有线网络无法连接

[白鬼_2015]

[

如图，升级前是15.04的系统。
刚装好时间有线能用，然后时而能用时而无法连接。（没做任何改动）
现在已经完全连不上了
困惑以久，求各位大神明示。

系统: win8.1+ubuntu14.10
product: Ethernet Connection I217-LM
driver=e1000e

刚刚突然又能用了，简直不可思议

你是双系统？
若是双系统，猜测你也是下面的情况

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。

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。

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

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

是否为双系统？若不是双系统，可能有另外的原因。
看你没提到网络唤醒。若为双系统，最关键一点关闭网络唤醒(Wake on LAN)。

若还有问题，重新执行一遍二楼的指令，把结果发上来。

大神明鉴，系统是win10+U 15.04
以前win8.1+U时没有这个问题。
BIOS里面的选项我已经关闭了。
我正在找win10的WOL这个选项在哪里。。。。
谢谢大神的指教。
