No, I'm not using DHCP, and the cables are fine.  I have a theory about
what it might be, though.  Is "system-config-network" related to
networkmanager, or is it something else?

I have disabled it and hopefully switched sucessfully.  I didn't have a
choice because even with /etc/resolv.conf set to read-only, it was still
being overwritten.
