Here is the ifconfig result:


To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

NetworkManager setting is:


# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in
# the file:
#
# /etc/default/NetworkManager

I'm new for ubuntu and I'm not sure what I can do and what I have to do.
I need your magical simple step by step help if you will please. Thank you,

Is this a new install of Ubuntu, Did it ever work?

If this is a new install, did you check the md5sum of the iso before you installed?
