New network cable run not getting a connection
A new cable run fails because it's not crimped correctly at the ends, it's plugged into the wrong port, or a switch port is switched off. First, make sure both ends are fully plugged in until they click. Then test the cable with a different working device.
Network cables are simple. If it works at all, the cable itself is fine. The problem is a loose connection, a crimped end, or a switched-off port. Fully plugging in both ends and testing with a device you know works tells you if it's the cable or something else. If a new cable never worked from day one, it was damaged when it was run through the walls.
- ✓Have access to the physical cable run and the switch or wall port it connects to
- ✓Keep a working ethernet cable nearby in case you need to test the port
- ✓Know which device or port you're troubleshooting so you can test it

Skip, I just want a technicianCommon mistakes to avoid
- Assuming the cable is bad without testing it with a device you know works
- Not checking that both ends are fully plugged in and clicked
- Trying to use a damaged cable instead of replacing it
- Forgetting to enable the port in the switch settings after installation
Signs you need professional help
- You've tested the cable with a known working device and it fails in every port, the switch port light never comes on even with a working cable, the cable is damaged and you need to have a new one installed, or you can't access the switch console to enable the port.
