Slow Network or Internet Download and Read Speeds using Intel Network Adapter

Leave a comment

You may find that Network and/or Internet speeds are very slow when using an Intel Network Adapter.

This appears to be an issue with the Speed and Duplex settings, after a Driver update or installation you may notice that the Speed and Duplex is set to 100 Mbps Full Duplex.

When running a LAN Speed Test it only reports a Read speed of 5 Mbps and Internet Speed tests also report terrible Download rates.

Upon changing the Speed and Duplex setting to Auto Negotiation the issue is resolved

LAN speed test and www.speedtest.net results after making this change both indicate the issue is resolved

Verify the Health and Operation of your Intel® Processor with the Intel® Processor Diagnostic Tool

A 32 and 64 bit version of the IPDT or Intel Processor Diagnostic Tool can be downloaded from here: http://www.intel.com/support/processors/sb/CS-031726.htm

You can also see a video on how to use it here: http://www.youtube.com/watch?v=tpPOqh_Bq78

You can use the diagnostic tool to test the various features of your Intel Processor and perform a stress test to ensure that it is operating in a  stable manner.

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.
