Intel I226-V. Unable to update driver on Intel NUC 13 Pro RNUC13ANHI5000U

[rimmi2002]

Hi,

I just bought the Intel NUC 13 Pro RNUC13ANHI5000U. I am having ethernet issues that I am trying to trouble shoot. 

One of the advice I saw in these forums is upgrading to latest drive 1.1.4.42. I am currently running 1.1.4.38. Followed the advice from below: 

2. Intel® Ethernet Adapter Complete Driver Pack,  through the device manager instead of using exe file and browse to update the driver from Intel Complete Driver Pack -> PRO2500 -> Winx64 and choose NDIS68 (for Win10, Win11, WS22)

I get the error shown in the screenshot. Is this the correct driver for my device? Do I need to do something different for my NUC?

Error in Device Status: (Screenshot attached)

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Windows cannot verify the digital signature for this file. The signing certificate for this file has been revoked.

Thanks in advance.

Have exact the same bug with an I225-V Lan. Before december Patchday from microsoft i had zero issues with 1.1.4.42 driver. Did fresh install from Win 10 december iso and the bug happened. On Windows 11 driver 2.1.4.2 is working fine. My conclusion is that we have a bug with latest Windows 10 KB. P.S previous 1.1.4.38 driver is workin fine too with Win 10.

If you are having slow speeds you can try this BIOS fix that I posted in the other thread that I created. Got this advice from someone at Reddit and it works great to solve all speed related issues.

It took me days to find the fix.  The final fix was at the Microsoft web site.

By the way, I used this version for windows 10 for my build. I downliaded yhe file, expanded into a directory. then wen to went to my first nic, and used update, and I have driver. Then I went to each nic and had it find the best driver on my sytem. Worked great..
