no problem Old, love that movie,saw it when it came out back in the day..everyone made a fortune off it..Stacy Keach my favorite..anyway,I just did a wireless ethernet link,works real good about a 250ft poke great speed and bandwidth..off Amazon.
Look into fiber transciever hubs as well,-they have Cat5 RJ45 input, fiber cable out..fiber in on other end converts back to RJ45 Cat5. The hubs are $65/ea and the fiber cable is cheap at about $150 for 400ft or so,ready made up ends already on it..cant go more than 300ft with Cat5 but you can go miles with fiber.FWIW
