How did you connect the RJ-45 jacks to the wire. If you reversed or miss-pinned any of the wires it won't work.
wondering if someone could help with a problem.i ran some cat5e cable in my office from router up the wall through the attic then down to other computers i think my longest wire run is about 100 ft. and not a single one of the three wires works. it tells me that a network cable is unplugged. router is working ends are crimped on right. if you have any suggestions they would be greatly appreciated. thank you
