IIRC, this is a common problem when multiple NICs are in place. IIRC,
one way is to include params in /etc/modules.conf (used to be - now
modprob.conf?). But an easier way, I think is to modify

replacing the hexidecimal numbers with the MAC address of your card.

I think this new-fangled GUI stuff has a way to do it with a panel.
