X540-T1 Performance in NDIS6 LWF

Hello, I am YongminKwon who previously asked questions related to the NDIS6 LWF
https://community.intel.com/t5/Ethernet-Products/X550-Performance-in-NDIS6-LWF/m-p/1224031

As a result of finding out about a Yottamark® sticker, it seems that the previous LAN card was also manufactured elsewhere.
So this time I bought an appropriate LAN card and tested it, but the same problem appeared.
Please refer to the previous question and answer it. I have attached a valid BradyID code and SSU file.
Thank you for all your assistance.

Thank you for waiting for our update.

After doing an initial investigation on your issue, here is our recommendation:

1. Please try driver version V25.5 (DriverVer = 12/19/2019,4.1.199.0) which can be downloaded from this page, https://downloadcenter.intel.com/download/25016/Intel-Network-Adapter-Driver-for-Windows-10?product=....

Hi AlfredoS,

Unfortunately, even if I downloaded and run the driver version V25.5(DriverVer = 12/19/2019,4.1.199.0), it did not work properly.
Thank you.

Best regards,
Yongmin.

Hi YongminKwon,

Thank you for waiting for our update.

We are humbly sorry for not getting back to you on the timeframe that we have suggested. We needed more time to thoroughly check on your concern due to the complexity of your issue.

Here are the findings of our engineers:


To give you information on what LWF stands for “Lightweight Filter Driver”. It’s a driver that sits between our Windows driver and the Windows OS (more specifically the Windows NDIS protocol). An LWF driver can monitor and *modify* the interaction between our driver and the Windows OS.

 

We checked the SSU logs thoroughly and found a few things.

1. You are using Windows 10 1904

2. You are using driver package 24.2

3. The X550 has the NDIS 6.5 driver installed, should be using the NDIS 6.8 for 1904

 

You also stated that the LWF is based on NDIS 6.2 which is for Windows 7.

 

In light with these finding, here are our suggestions:

There are 3 different NDIS versions in this scenario,

1. Update the drivers to the current version using the NDIS6.8 versions

2. Rebuild the LWF and base it on NDIS6.8

3. And make sure that the X550 NVM is up to date

So you would not have be complicated by so many variables

 

Also, for your questions about the capabilities of the X550 please check these links:
