Re: [Question #77152]: need help : ifdown interface eth0 not configured

 

Question #77152 on network-manager in ubuntu changed:
https://answers.launchpad.net/ubuntu/+source/network-manager/+question/77152

    Status: Open => Answered

Jeruvy proposed the following answer:
Try to bring eth0 up:

$ sudo ifup eth0

If this fails go ahead and edit the interfaces file to see if it needs
to be configured.

$ gksudo gedit /etc/network/interfaces

It should have the following, feel free to add if its missing:

auto eth0
iface eth0 inet dhcp

If you made any changes to this file, save it and quit, then restart the
network

$ sudo /etc/init.d/networking restart

Good luck,
