I have cat5e Ethernet cabling installed in my house by the builder. However, I cannot get any signal when I connect them to my router (no lights on the modem port or switch and router light red). I have connected the ends myself and tested them using a network tester. They all show that the ends are connected properly. The Ethernet cabling shares telephone also but I disconnected the phone wires and connected the 8 wires to the RJ45 jack (tried keystone patch but didn’t work either). I can’t get any signal via the cabling. I think I have tried everything except calling in a professional.
