Ethernet connection

[JuanG]

I am experiencing low speed using my Ethernet connection L219-V, my internet connection is around 400 to 500 mb/s and a couple of weeks ago my internet started fluctuating a lot and giving me speeds of 20 mb/s I changed the cable and updated the drivers directly from intel webpage, also did it from the ASrock webpage and nothing has been working to fix the issue. I connected my router to my old pc and it doesn't have a issue with ethernet speed. what can I do to fix the problem.

Thanks

Hi @JuanG , based on your issue, i found article from Intel. Kindly check the below link:

https://www.intel.com/content/www/us/en/support/articles/000093547/ethernet-products/gigabit-ethernet-controllers-up-to-2-5gbe.html

ALong with that, you have mentioned that is it built-in with Asrock Mobo is it? If yes, have you check with Asrock Support for this.

This is because when its come builtin with mobo, the mobo brand they have their own set of driver to fix with their mobo.

Hope this may helps you...

Hi JuanG,

Hope you are doing well.

Thanks for reaching out to Intel Community Support.

Pertaining your issue, we would appreciate if you can perform the troubleshooting steps listed below and let us know the outcome.

1) Double-check if the established connection speed in the settings can reach 1Gbps. To confirm this, go to Network and Internet Settings. View your Network Properties and scroll down to Link speed (Receive/Transmit).

2) Ensure that the Model/Access-point/Switch or device on the other side comes with full Gigabit support.

3) Test the speed on another system to ensure that it is not an issue regarding cable, operating system, Internet, and hardware itself.

4) Update the driver to latest version. If Intel® Ethernet Controller is embedded on Original Equipment Manufacturer (OEM) system, it's best to check with the manufacturer as the software drivers linked from Intel page are generic versions, and can be used for general purposes. To avoid any potential installation incompatibilities on OEM system, Intel recommends checking with the OEM and use the software provided via system manufacturer.

5)Ensure that Speed & Duplex settings on Advanced tab property of the Intel Ethernet Controller is set to Auto Negotiation.

6) Lower the value or turn off interrupt moderation as this is best for handling many small packets so the driver is more responsive to incoming and outgoing packets.

7) Disable other I219-V features such as offloading, Energy Efficient Ethernet, and flow control.

If the system comes with TurboLAN Cfos, disable the service called cFosSpeed System Service. Closing the program doesn't make any difference, as that service keeps running in the background.

9) Run netsh int tcp set global autotuninglevel=normal on command prompt to check if the issue is bug related to Windows Auto Tuning
