Most ethernet connections in Hardy will "just work", however there may be some circumstances where extra configuration is needed. If you are having trouble connecting, first make sure that cables are connected properly,and that you have the right cable. Then check the network applet (icon in the upper gnome panel that looks like two monitors, one slightly in front of the other). If it has an orange spot, it is not connected (though this is not a reliable feature in dialup and wireless connections). If it says it is connected (no orange spot), check the ip address (right-click>Connection Information). If the IP address is zeroes or starts with 169, then it is not really connected.

Things to try.

Right-Click, Click to remove the check mark on "Enable Networking", then do it again to re-enable. This will cause the box to ask for a new address.
Go to System>Administration>Network
- Make sure that all interfaces are set to roaming mode
Cable and dsl modems often have to be rebooted before they will connect with a new computer. Try turning off the computer, modem and any intervening router or hub and then booting them in order, starting from the one nearest (cable distance) to the wall.

-Most Freekbox 3 machines are configured with ifplugd, which automatically brings the ethernet interfaces up and down.  They are set up by default to use DHCP and so will work without change with most DSL and cable connections or local networks with a router.  For static ip's read below.
-In a freekbox2 and some early freekbox3s, the ethernet interface is normally not configured. On those older boxes, therefore, some configuration must be done before the box can connect to either a network, or a dsl modem. Most networks require machines to be set up to use DHCP, which automatically assigns IP addresses and other related information, or in some cases one needs to set up a static IP.
-To set up the interface in Debian, use your favorite text editor (as root) to edit the file "/etc/network/interfaces", for example:
- nano /etc/network/interfaces
-==DHCP==
-Most network situations will use a dynamically configured ip address (DHCP).  The following lines are needed in /etc/network/interfaces.
- auto eth0
- iface eth0 inet dhcp
-On a freekbox, /etc/network/interfaces should contain the "auto eth0" line as a comment and the dhcp line is already uncommented. simply remove the "#" before auto eth0 and it should be set.
-==static==
-For static ip configuration, /etc/network/interfaces needs the following lines:
- auto eth0
- iface eth0 inet static
- address 192.168.0.20
- netmask 255.255.255.0 (substituting your own values)
- broadcast 255.255.255.255
- gateway 192.168.0.1
-== Static DNS ==
-DNS information is set in "/etc/resolv.conf".  An example of the file is below:
- search freegeek.org
- nameserver 198.107.0.14
- nameserver 206.26.36.34
-Most people using DHCP will not need to edit this file, though there are exceptions.
-==Bringing up the interface==
-THEN one needs to bring up (or take down and then bring up) the eth0 interface with the following commands issued as root
- ifdown eth0
- ifup eth0
-OR simply reboot the machine, which will accomplish the same thing, since the "auto eth0" line will cause the interface to be automatically configured at boot.
