Do you allow the installer to continue anyway?  I had to, and then
finish setting up networking after the reboot.

What does ifconfig show?

Also (and I know this may sound silly) check to make sure that the
network cable is plugged into the right NIC.  If you have three NICs
then they may not be getting assigned the way you think.  Mine swapped
over after installing X/KDE for some reason.
