Windows 10: broken Ethernet adapter driver - sees it as CD Drive

windows 10 version: 1909 - 18363.778

Hi I have an obscure annoying issue, similar to here
https://answers.microsoft.com/en-us/...0-3d8c3a714f3c

On my Lenovo IdeaPad Flex-14API a few weeks ago my Cable Creation gigabit ethernet to USB 3.0 adapter started giving me this autoplay popup as a CD Drive D: whenever I plug it in. It appears in Windows Device Manager as a USB Mass Storage Device, not how it should be under Network section as Realtek USB GBE Family Controller as here:

It no longer works to plug into other devices to act as an ethernet cable for network diagnostic / testing (this laptop lacks a proper Eth port, hence the adapter). This is weird because Ive done nothing before a few weeks ago when it was working. I have since tried updating all system and network, usb drivers. I installed the Cable Creation manufacturer driver for the adapter. Still get this weird issue. I tried running as administrator the RTK_NIC_DRIVER_INSTALLER.sfx application within the popup drive D, and it basically does nothing but the Drive D disappears temporarily. Anyone have an idea for a fix? Need this for work.

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs

 

Driver for Ethernet Adapter

Hi,

Welcome to Microsoft Community and thank you for your interest in Windows 10.

You might be facing the issue due to the incompatibility of the network drivers with Windows 10. So, I would suggest you to uninstall and reinstall the network drivers and check.

Follow these steps to uninstall Network Adapters.

• Press Windows key + X and select
  Device Manager.
• Search for Network Adapters and expand it.
• Right click on the network adapter
  and select Uninstall.

Now, I would also suggest you to go to the manufacturer’s website and download the drivers for Windows 10. If the drivers for Windows 10 are not available, then you can download the drivers for Windows 8.1 and install them in compatibility
mode and check.

Make older programs compatible with this version of Windows

Constantly disconnecting with ethernet cable

Hello,

Thank you for keeping us posted on the status of the issue.

I suggest you to check if rolling back the Ethernet driver helps to resolve the issue. Follow the below steps.

• First of all, Press Windows logo + R from keyboard. It will open
  RUN.
• Now type devmgmt.msc and press Enter to open Device Manager.
• You will see all the device list of your PC. Expand Network Adapters

Rollback driver

Double click on your Ethernet driver in Device Manager. Then Click on
Driver tab and select Rollback.

Important: If your drive is performing well and there is no error, Rollback driver button will be grayed out as an option.

If it still does not help, I suggest you to reinstall the drivers for the Ethernet driver and check if it helps to resolve the issue.

Note: Once you uninstall the drivers the Ethernet adapter device will be disabled and you won’t be able to connect to internet. So it is advisable to keep all the installer files as a back up in your hard drive.

Write to us with the results for further assistance.

Thank You.
