Hello, I am YongminKwon who previously asked questions related to the NDIS6 LWF

Inquiries with LAN card manufacturer is in progress and I would like to ask additional questions.

I am having the same problem with the Intel X550 as well as the X540 in the previous question.

Please refer to the previous question and answer it. Also I attached SSU file.

Hi Yongminkwon,

Thank you for waiting for our update.

While we were checking, these questions came into mind which will help us find a recommendation for your issue:

1. Did your x550 card came from the same company? If possible, please provide us pictures of the front and back of the card focusing on the markings on the sticker.

2. What did your system manufacturer advised you so far?

We look forward to your reply. Should we not get your reply, we will follow up after three business days.

Hi, Alfred S

The SSU file attached to the main text is the product of NEXT as before.

We are in contact with the manufacturer, but we haven't received a specific answer.

So, while testing with various LAN cards in progress, the same phenomenon occurs with LAN card manufactured by Intel, so I attach SSU files and images.

It would be good if you solved the Intel LAN card first.

If there are good answers from other manufacturers, we will share them with you.

Thank you for your assistance.

Thank you again for the additional information that you have provided.

We are already on the initial phases on our investigation for your issue.

While we are checking we found the need to confirm the following:

1. The NDIS6 LWF that you are using was self-developed by your company, is that correct?

We look forward to your reply. Should we not get your reply, we will follow up after three business days.

2. If your answer to question number 1 is yes, please provide us a brief information on what customizations and features have you incorporated on the drive.

Hi, Alfred S

I'll answer about your question briefly.

We are using a filter created by modifying LWF from the samples in the WDK link below.
And NDIS is based on version 6.2.

WDK Link: https://docs.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk

The amount of data we want to use is 1115.5MB/s (50MB x 22.31FPS).

I also attached the version of Windows I am using.

How can it be used in these conditions?

Thank you for your assistance.

Hi Yongminkwon,

Thank you for waiting for our update.

We would like to confirm if your X550 adapter is a genuine adapter. We cannot locate the part number on our list. Please check if you card has a Yottamark® sticker. You may refer to this page, if you need reference on what it looks like, https://www.intel.com/content/www/us/en/support/articles/000007074/network-and-i-o/ethernet-products.html

We look forward to your reply. Should we not get your reply, we will follow up after three business days.

Hi Alfred S,
I am very sorry for the late reply.

As a result of finding out about a Yottamark® sticker, it seemed to be a product from another manufacturer.
So, I bought a genuine Intel LAN card and tested it, but the same symptoms appeared.
So I posted a new question in the link below.
Sorry again for the late reply. And thanks all the time for help.

Hi Yongminkwon,

Thank you for the quick response.

We need to close this thread since the model of the network card is different from the one listed on the other thread and it is the one having issues.

We will continue to assist you on the other thread.

If you need any additional information, please submit a new question as this thread will no longer being monitored.

Thank you for contacting Intel® and have a great week!
