Can you connect the two machines back to back with a crossover cable.
Does the speed improve?
Check both nics to ensure that they are negotiating the fastest
possible connection between the two boxes, full duplex.
Do you have any hubs or switches in your network?
Your router - it CAN support 1Gb connections can't it and both your
laptop and desktop also have 1Gb NICS in them? The network will fall
back to the slowest device in the chain, so finding out what speeds
are supported by each of the pieces of hardware in the chain will give
you an indication of what you can expect from the network performance.

people suffer from a delusion it is called religion.
