Wifi is very reliable if signal strength is sufficient. Use a couple of 
directional antennas... they can be purchased with a lot of gain. Copper 
to the shack would be hazardous (I have quite a bit of negative 
experience with long serial cables for Unix networks) and fiber, though 
ideal, would be pricey and would need to be run in a pipe.
