• What to do about cabling long distances and signal strength fading?

    I made a connection using Cat 6 SYSTIMAX cable from the server switch to the next repeater, which is 85 meters - and then to the next point it is 50 meters and then 50, then 50. The problem is the signal strength is not that strong and its on and off. What do you advise me to do? Thank you.
