I reset ADSL modem router but still have the same problem.

I can detect Ethernet for once and every think was OK, but when I restart still have the same problem. Should be a command to fix this issue :(

Hi it looks to me that your eth0 does not get an IP address. Are you sure that a DHCP server is running on that cable? The second OS is it connected to the same networkcable or does it use wifi?

@Stefan I have a simple network, just is a ADSL modem. Yeah, I'm sure.

First thing to notice is that you don't have a physical link (ethtool's output). There's no point diagnosing anything above this layer before this works. Have you tried connecting this port to another machine's Ethernet port and seeing if you get a link?

My laptop have problem so I connect laptop to pc (rather than laptop to ADSL modem) for now every thing is OK. But how can I connect laptop to ADSL modem?
This problem related to Ubuntu because I check several time on Windows 8 and have no problem.
I reset ADSL modem router but still have the same problem.
UPDATE3
I can detect Ethernet for once and every think was OK, but when I restart still have the same problem. Should be a command to fix this issue :(

Hi it looks to me that your eth0 does not get an IP address. Are you sure that a DHCP server is running on that cable? The second OS is it connected to the same networkcable or does it use wifi?

Hi it looks to me that your eth0 does not get an IP address. Are you sure that a DHCP server is running on that cable? The second OS is it connected to the same networkcable or does it use wifi?

@Stefan I have a simple network, just is a ADSL modem. Yeah, I'm sure.

And the other question: "The second OS is it connected to the same network cable or does it use wifi?" ?

First thing to notice is that you don't have a physical link (ethtool's output). There's no point diagnosing anything above this layer before this works. Have you tried connecting this port to another machine's Ethernet port and seeing if you get a link?

Try doing the next steps and change BaseT by 10 100 or 1000 according to your network card:
Ldentify physical eth0 port: ethtool --identify eth0
Look config eth0: ethtool eth0
Force Ethernet to full duplex 100Tx: ethtool -s eth0 speed 100 duplex full autoneg off
ifdown eth0 && ifup eth0
service network restart
