So early in the morning I might give wrong answers but...

The default gateway in this case shouldn't be the PC. There's a IP-address given for gateways actually not exists in the network.
I would suggest you use 192.168.1.254 as the default gateway (for PC and Empeg as well).

Something else:
What does the System Configuration (via control panel) says about the status of your ethernet card? Is it OK or does it have a questionmark or exclamation?

Good luck,

Eize
