Hi Skinleech,
With gigabit, the quality and the length of the cables become critical factors.
If you are using cat5 instead of cat6, they must be of best quality.
The best way to troubleshoot, but a bit messy for you, is to put the pc's close together in one room, and use short, new and high quality cables.
100mbit uses only four wires of the eight.
Gigabit uses all eight, thus making crosstalk more likely.
That's why you should use cat6 cables.
