I had an issue with wireless redstone, i think it has something to do with Redpower (because it is in beta atm), but this being said i honestly don't know how to fix it. My issue was that certain frequency wouldn't work, as were the ones that are under 100 or so did. none the less this mod can very taxing on a server (anything that does wireless/teleportation of items). The only real good use for wireless redstone was for frame engines but you are only adding maybe a block or two more for the wires really
