the lights at the back of the craddle are on but not blinking.

Are both lights on, solid and steady?

If so, no IP address setting is going to help you, that's a frozen ethernet port. It's died during the initial handshaking negotiation where it's attempting to set 10/100 and Half/Full duplex.

I get this problem on the Linksys switch I have at home.

You can *try* forcing your ethernet card to 10 full duplex or 100 half duplex and see if that fixes it.

A working ethernet port will have only one light on steady, and the other light will be off most of the time except it will blink when data is being transferred on the network.

- the manual says to pick an IP address for the computer in the range of 192.168.0.x What address should be put in the Karma manually?

Assuming you can get the ethernet port working at all, you should set:

PC:
IP address: 192.168.0.x
Subnet Mask: 255.255.255.0
Gateway (Leave Blank or all zeroes or whatever it takes to count that field as disabled)

Karma:
IP address: 192.168.0.y
Subnet Mask: 255.255.255.0
Gateway (Leave Blank or all zeroes or whatever it takes to count that field as disabled)

Note that "x" and "y" in the above two descriptions must be different. For instance, the PC could be 1 and the Karma could be 2, but they can't both be 1.
