Problem With Internet Under Easy Peasy

Question

I have an Eee PC 904D that i use for development, because it's tiny and little, but i have a PC too. But in my Eee PC that i have Ubuntu Intrepid Ibex with the Netbook Remix(Easy Peasy), when i want to use the ethernet cable for the internet i connect it and tryes to connect, but in aproximatly 10 secs trying to connect it fails and change the icon like i don't put any cable, but the cable is connected and other computers when i try to use this cable connect normally, if is needed here is the content of /etc/dhcp3/dhclient.conf file:

# Configuration file for /sbin/dhclient, which is included in Debian's
#   dhcp3-client package.
#
# This is a sample configuration file for dhclient. See dhclient.conf's
#   man page for more information about the syntax of this file
#   and a more comprehensive list of the parameters understood by
#   dhclient.
#
# Normally, if the DHCP server provides reasonable information and does
#   not leave anything out (like the domain name, for example), then
#   few changes must be made to this file, if any.
#

send host-name "<hostname>";
#send dhcp-client-identifier 1:0:a0:24:ab:fb:9c;
#send dhcp-lease-time 3600;
#supersede domain-name "fugue.com home.vix.com";
#prepend domain-name-servers 127.0.0.1;
request subnet-mask, broadcast-address, time-offset, routers,
    domain-name, domain-name-servers, domain-search, host-name,
    netbios-name-servers, netbios-scope, interface-mtu;
#require subnet-mask, domain-name-servers;

#reject 192.33.137.209;

#alias {
#  interface "eth0";
#  fixed-address 192.5.5.213;
#  option subnet-mask 255.255.255.255;
#}

#lease {
#  interface "eth0";
#  fixed-address 192.33.137.200;

#  rebind 2 2000/1/12 00:00:01;
#  expire 2 2000/1/12 00:00:01;
#}

Here is the ifconfig log:

Answer 1

Have you tried network-manager? Network manager doesn't use dhclient.conf. You can find its configuration under /etc/NetworkManager but it's best done using the configuration dialogs.

Answer 2

Does it get an IP address? type "ifconfig" in a console and look for an address for eth0. If it gets an IP address, try to ping another machine by its IP.
