I recently installed Fedora Core 4 on an old computer I had laying around. The reason for Fedora Core 4 is that's what I had laying around. Everything installed and I set the system up the way I want it run. It was working properly. I was using kernel 2.6.11.something. I upgraded to the latest kernel version 2.6.17.something. After rebooting my computer, my internet connection, samba and everything network related is lost. What happened? I check the network card in the back of the computer first to see if the light is green which it is. I check my network card drivers and it appeared to be working properly. Where should I go from here? Any help would be greatly appreciated and thanks in advance.
