okay, i dont know where else to post this, so here is my problem.
i am making a computer send out a rednet signal to another computer that is looping and when it gets the signal, it runs a program on a monitor, i cant get the code i have written cause it is on a server but basicly, i have a login system and after any user logs in it opens the doors, turns on the lights and sends a signal to run the monitor, everything works except the rednet signal gets lost, the two computers are less then 10 blocks away, and i cant figure out the problem
