To get ethernet working... connect to the empeg with emplode via your serial cable. the under the File menu, select Configure Player. Select the networking tab. If you just have a hub and an internal network behind your cable modem, you'll probably want to click Manual Configuration, and assign a non publicly addressed IP... something like 192.168.1.* (* being any number below 254 i believe?). netmask could be 255.255.255.0, and the default gateway would be your modem ip address. Then sync, and see if you can connect with ethernet then. =]
