Windows 8.1 DisplayLink Network Adapter Error with 7.4 M2

[JamesH]

Hi,

It's possible it's picking up the wrong driver even after uninstallation.

Can you try these steps:

From device manager right click on the USB Ethernet device
Select uninstall and be sure to select "Delete the driver software for this device"
Select OK
From device manager select the Action menu and select "Scan for hardware changes"
Select "Other devices" from within device manager
Select the USB Ethernet device
Select “Update Driver Software” -> "Browse my computer for driver software" -> "Let me pick from list" ->”Have disk” -> Select "Network Adapter" -> Select Browse -> Select "C:\Program Files\DisplayLink Core Software\CdcNcmDriver\Ndis6.2.Hck81" -> Select "Next"

Let me know how you get on.

Thanks,
James

This worked for me! Lenovo ThinkPad Twist s230u Windows 8.1. I was also getting the same error as rhysgibson:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system's image of the Registry.

Cheers!!

Hi James,

This is not working for me. Lenovo USB 3.0 dock is saying that the ethernet cable is unplugged even after replacing with the latest drivers that you mentioned. This worked fine before the upgrade to Windows 8.1. Running 7.4 M2.

Edit: attached logs from support tool

This is a different problem to the other users on this thread. Your Ethernet is detected by Windows, but the link appears down. Are the LEDs on the Ethernet port of the dock on? If not, then there really is no Ethernet link.

I believe this is still related to the drivers. Everything worked before the upgrade to Windows 8.1. The ethernet even worked after the 8.1 upgrade before I upgraded to 7.4m2 (the display did NOT work before the upgrade). So now I have display working, but ethernet not.

Your logs show:

Ethernet adapter Ethernet 2:

Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Lenovo USB Ethernet
Physical Address. . . . . . . . . : 00-50-B6-60-C1-56
DHCP Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes

This means that Windows has correctly loaded the Ethernet driver and can see the Ethernet port, but thinks there is no connection. This means that it is different to the driver code 31 error seen on this thread
