Ok, so I have read all of the topics on the Internet that say that you can't take cat5 longer than 100 meters. I know people that have, but they say that the speed just drops to about 10mb per second. I need to run the cat5 about 400 ft and then another 175 ft. I am going to put a router inbetween to kind of, rejuice, the signal. Questions. 1. anyone know for sure based off of experience what the actual limit on cat5 is? 2. I have my l-com tester. I currently have about 500ft capped on both ends and am testing it, yet don't really know what the readout means. Numbers "4&5" and "7&8" are flashing. Oh, btw, I have model dxb64a. Any help with this is much appreciated!
