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 almost always 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 probably damaged when it was run through the walls.

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
