So, I just terminated my first rj45 cable and it all seemed to go well until I tested it. I use the following tester AUCAS Network Cable Tester rj45 RJ11 Network LAN Ethernet RJ45 Cable Tester tool-in Networking Tools from Computer & Office on Aliexpress.com | Alibaba Group The cable I'm using is Siemon Cat6a F/UTP and the connectors are: - Siemon Z-Max Keystone Benefits of Z-MAX Category 6A Cabling Systems: UTP and Shielded - Aucus Aucas CAT7 RJ45 plug shield FTP 8P8C Network Crimp Connector-in Computer Cables & Connectors from Computer & Office on Aliexpress.com | Alibaba Group As I was using a keystone on one end I had to use another cable between it and the tester. Its a cat6E cable (yes E). Now, the test results. It blinked 2,3,4,5,6,7,8,G and missed 1 So, I re terminated the rj45 end and got the same result. Then I re terminated the keystone end the result.... 1,2,3,4,5,6,7,8,G Later I decided to show the wife my good work and I got 2,3,4,5,6,7,8,G again So, I turned the cable around and 1,2,3,4,5,6,7,8,G.....hmmm Tried another cable, a cat5E that came with the my powerline adapters and I got 1,2,3,4,5,6,7,8,G no matter which way he cable was plugged in. More testing, different cables, some the 1 light flashed, some it didn't........ Also, it seems to make a difference if the slave or master is plugged into the keystone. Anyone know whats going on here? Do I need a better tester? As always any help is greatly appreciated.
