Sounds like you need to study some basic info on networking and IP
addresses.

Are you using DHCP from the router to provide IP addresses to your
computers? Or are you trying to configure static IPs?

Here is a simple example. Let's say your router assigns itself a private
IP of 192.168.1.1 for your internal network. This would also be your
gateway address. (Most of the home-use DSL/Cable routers have an internal
gateway IP of 192.168.0.1, or 192.168.1.1 or 192.168.2.1, though there can
be others.)

That means your computers behind the router will need IP addresses of
192.168.1.X (to use the example, and where X is a unique number other than
1.) They will have a subnet mask of 255.255.255.0. If you are using the
router's DHCP server, the router should assign these numbers
automatically.

Your gateway IP on each machine should be the IP address of your router,
or 192.168.1.1 in this example.

Most home routers also provide a DNS service, so you should be able to
show the DNS as 192.168.1.1 also. However, you can add in the IP addresses
of any other known DNS servers. Once again, using DHCP on your
computer should pick up the correct DNS address from the router.

Also, in your network settings (you can access the GUI interface as
discussed earlier), make sure your settings are "Active". If you can't
activate your network card, this probably means some underlying setting is
misconfigured or has another problem. As noted, I've made a lot of
assumptions given the paucity of info available. One of those
assumptions is that when you installed FC3 that it correctly detected and
configured your network card. At the command prompt, try typing:
  /sbin/ifconfig
and see if you have an eth0 network device configured. Here is my output:
 eth0 Link encap:Ethernet HWaddr 00:D0:2E:32:54:44
        inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0
        UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX
        packets:2745736 errors:0 dropped:0 overruns:0 frame:0 TX
        packets:6321589 errors:0 dropped:0 overruns:0 carrier:0
        collisions:0 txqueuelen:1000
        RX bytes:1907643864 (1819.2 Mb) TX bytes:2764552303 (2636.4Mb)
        Interrupt:11 Base address:0xdc00
You should get a similar output.
