Hi Lucas Fraser!

First things first, do you have the green lights?  Usually when you
plug the ethernet cable into the computer or modem a little light or
two will change usually to green to show you that the physical
connection is working.

Next we move on to the ethernet controller, does the internal PCI bus see it.
# you may need to do /sbin/lspci - Fedora often does not include /sbin in $PATH
--------------------------------------
tod tod-desktop:~$ lspci | grep -i eth
0000:00:0b.0 Ethernet controller: 3Com Corporation 3c905 100BaseTX [Boomerang]
tod tod-desktop:~$
----------------------------------------
If you drop "|grep -i eth" you can see all on the bus.  if you add a
"-vv" to "lspci" you can see the very verbose output.  Anyway you can
see that the command found my Ethernet controller.

The problem of seeing if the appropriate driver is installed I have
not yet resolved.

You say you have no IP.  I would guess that you are useing?
---------------------------------------
tod tod-desktop:~$ ifconfig

tod tod-desktop:~$
------------------------------------------
Ifconfig shows my ethernet up, with IP and pretty ready to go.  Next,
do we have a route?
-----------------------------------------
tod tod-desktop:~$ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 eth0
default         192.168.0.1     0.0.0.0         UG    0      0        0 eth0
tod tod-desktop:~$
-----------------------------------------
The first line shows the route to the 192.168.0.0 network (where I am
192.168.0.18 as shown in ifconfig).  The second shows a default
gateway which will be (is) where packets addressed to somewhere else
(www.linux.org) will go.  You are not quite yet to the point where you
are troubleshooting Internet connectivity but there be a preview.

Good Hunting!
