For the record, you don't need the MAC address to set a static IP unless your router is set to only accept connections from specific MAC addresses, and generally you can get the MAC address from your Router, the DHCP configuration side should show which MAC addresses are given IP addresses.
Just set your static IP to 192.168.0.99, something outside of the DHCP range, and you should be okay.
I know with Genesis on my A4000D with the Ethernet through the Mediator, I had to set my IP to static. Couldn't ever get DHCP to work correctly for some reason.
Worked perfectly after that.
