Asus AC68 PCI-E Wireless adapter not working after Windows update (Code 38)

As the title suggests, after the most recent Windows update (brought my version of Windows to 1803), my Asus AC68 PCI-E Wireless adapter ceased to function. According to Device Manager, it was a "code 38" error (Windows cannot load the device driver
for this hardware because a previous instance of the device driver is still in memory.)

Multiple searches have suggested that this is because of an issue with AMD processors, but this is not my situation as I have a Intel based processor.

I have attempted the following troubleshooting steps (without success)

• Uninstall and reinstall the driver
• Use to "PCI lock" function in msconfig
• Restore my computer to a previous state
• Delete the Asus software
• Change PCI port of my card

The only step I could take that did work was to restore a previous version of Windows (it brought me back to version 1709). So, for the moment my card works again, but my PC wants to update again, and I feel like this whole process will begin again if I
do so. For the record, I have already been in touch with Asus support, and they have been less than helpful (some of the steps taken above were at their suggestion). Thank you in advance for any advice.

 

List of PCI devices

Hi

My name is Lester and hopefully, this will help answer your question, there are many ways for us to check the PCI slots available on the PC, you may refer to the steps below:

Method 1.

Press Windows key + R then type in regedit then hit OK

Locate the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\

By that you can check PCI information.

Method 2.

Press Windows key + R then type in dxdiag then hit OK

On the bottom click Save all information

You may save it to your desktop or anywhere, once done open the saved information to notepad.

Look for System Devices and you will see the list of PCI, on notepad you may also search for PCI by pressing CTRL+ F then type in PCI to check.

Let me know how does it goes, and we have sets of troubleshooting steps here.

Way to disable PCI-E link state changing?

  I was scouring the internet for the reason the version changes, but came up empty.
  
  
  I'm guessing it has to do with power saving, good analogy is speed step/turbo mode on a CPU. It does draw some additional power run the PCIe bus speed at full throttle.
  
  
  Summary of PCI Express Interface Parameters:
  • Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
  • Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
  • Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
  • Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/
