When, and where, *exactly* do you get this message?

I doubt that the install, even from an 'all-on-one' distro, sets up 
EVERYTHING. That's what we are trying to discover: what is missing or wrong.

This works at the computer level: your computer sets the address.
To set a static address, on your computer (and this assumes a fedora 
install) use system-config-network or go in through System Settings -> 
Network Settings. The button you want to set is marked 'Statically set 
IP addresses (or Manual IP Address Settings). Enter an address in the 
same range group as your router (something like 192.168.1.200 for you 
box), subnet mask is 255.255.255.0 and the gateway address is the IP of 
your router, generally 192.168.1.1 or 192.168.0.1 depending on the 
manufacturer.
Then reboot.

There is a completely different and equal method if you are using a 
router. This makes the router give out the address you want it to give. 
Using this with all of your boxes, playstations, iphones, tablets etc. 
means that everything will always be in the same place.

Using a browser, enter http:/192.168.1.1 (or ...0.1) and you should see 
the default admin page for your router. On that you can select and set 
'Static DHCP' or something like that. Enter the MAC address of the 
computer (found with 'ifconfig') and then the IP address you want. Save 
and exit.
