With the Linksys device being plastic, I dont know how effective
shielded cables would be. Not to mention they are usually more
expensive than the non-shielded ones. Have you tried putting toroids on
the network cables ? That might knock down the birdies a little bit.
Might not be a bad idea to put a toroids on the power cable to the
Linksys as well. Shouldnt need to but I am looking at possibilities.
