you must left out some driver1394(firewire) connection is not for lan.
you need sth like "local area connection".
try with "device manager", check whether there is any network adapter on your computer or there is any device on your computer not installed properly (means need driver).
Are you sure you have an onboard lan adapter or only a 1394 adapter?
from user guide: on-board lan--build in Kinnereth-
chipset
check with device manager already and can find network adapter with a driver properly installed.
