Do they have a set range? I'm running a pretty extraordinarily long chain of about 1,700 blocks [Wireless is so power expensive ] I don't seem to be getting my items on the other side. I've gone through and checked a few times and I'm 100% sure that all the cables are connected. Again, do they have a set range? Or do they have to be chunk loaded? I really need help, all these cables were heck-a expensive!
