Hi,
My laptop is able to connect to wifi easily but is not working for wired connection.
this is what I get when I try ifconfig:

surbhi@surbhi-Precision-M2800 ~ $ ifconfig

My personal thought is that my eth0 does not have an IP address setup. But I thought that it would happen automatically.

Any help would be appreciated! Thanks

type in terminal,

I have tried doing it, it did not work . Still I don't get internet access but it shows that the wired network is connected.

is that not stating that his eth0 is up and running already?
then, if yes, would not taking down his wifi so that the unit would then be "forced" to use the eth0 to get out would then take place?

because his wifi maybe taking precedence over his eth0

mod:

i know on Network mamager it had a selection for
right clicking on applet, un-select enable wifi, enable network is still in effect.

it is a simple try if you are running an applet such as that.
or
comman line commandO on it even.
