Intel Network Adapter Diagnostics May Wrongly Report that the Network Cable is over 100 Metres Long

When you run a Cable diagnostic using the Intel PROSet Network Adapter Diagnostics you may find that the utility incorrectly reports that your network cable is over 100 Metres and/or that the Cable is faulty/poor.

This issue can occur if you have a network switch that implements “power Saving” or “Green Ethernet”¬†this feature is meant to reduce the power to a network port that is supporting a device with a short network cable run.

This “power saving” or “Green Ethernet”¬†feature can cause the diagnostics to fail and can sometimes contribute to network drops and/or poor network throughput.¬† If you have a managed/smart switch then you can normally login via a browser and “Disable” this feature to correct the issue.
