Make sure you are using CAT5 cables.
If you are putting ferrite chokes, make sure they are at both ends of the cables. 
Check the router and its power cord that they do not radiate and form the ground loops between them and rest of the computers.
You could shield the CAT cables by using some braid and grounding it at one end.
