Hi,

Any help?

There is no IPv4 address in there. I would have expected the second line to look something like...

Code: Select all

          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
...with the 'inet6 addr' line following it.

What does `nm-tool` say? Also, are we talking about MATE, Cinnamon, or something else?

Under...

Control Center > Network Connections

...on the "Wired" tab, select "Wired connection 1" and then click the "Edit..." button. On the "IPv4" tab, ensure that "Method:" is set to "Automatic (DHCP)".

(I see results similar to yours if I set the method to "Disabled".)

It was set already and enabling the "Require IPv4 addressing for this connection to complete" doesn't change anything. ipconfig -a still does not show an ipv4 line on eth0.
I have to use 802.1x Security for the connection but on Mint 13 I just got to the 802.1x Security Tab in the network Edit window and set it up properly and then it worked..

Also what is this "lo" interface?

I see. That's something I've never had to set up before. I hope somebody else can help you.
