Intel AC-8260 Adapter temporary not found or not working

[idata]

Since 4 Weeks i have the problem, that temporary my Intel AC-8260 adapter is not found with code 45 (Adapter is not connected to the system)

or with Code 31, Windows could not load the drivers.

I have a Lenovo X1 20FC Laptop.

The amazing thing is, that sometimes everything works fine and one day later, the problems comes again.

So i made few things, like:

- Installing all the newest drivers for AC-8260 from Intel (act. Version: 20.70.1.1).

The device Manager says:

At starting the adapter ROOT\NET\0000 there is a problem.

Driver Name: oem61.inf

Klassen-GUID: {4d36e972-e325-11ce-bfc1-08002be10318}

Dienst: Netwtw06

Lower Filter:

Upper Filter: vwifibus

Problem: 0x1F

Problemstatus: 0xC00000BB

So the sing is, i dont kow, if it is a hardware problem or a driver problem.

May somebody has the answer :-)

Best Regards

Hello Wanner G.,

i done all the clean install steps.

First is then, that the network adapter is not found in the device manager.

I run then the Intel® System Support Utility, you found the report attached, SSU-05-10-2018-01.

After that i done a manual installation of legacy hardware in the device manager for the network controller.

I run the Intel® System Support Utility again, attached report, SSU-05-10-2018-02.

Thank you for support

Hello MrEd74,

Thank you for your response.

I noticed that you are using Windows* 10 Version:"10.0.17763 Build 17763". Was this a Windows 10 Insider Preview when the problem started happening?

Also:

-Was the wireless adapter replaced?

-Did you install a device or make a change in Device Manager just before the error code appeared?

This is no insider Preview Version. Was automatically installed by windows update.

yesterday came new version, automatically by windows update to Windows 10 Pro Version 1809, Build 17763.1

No, the adapter was not replaced. Inside since bought 2 years before.

No device installed, i have this configuration since 2 years.

after restarting 5 times today, the adapter works again...

But i think this is only temporary, cause yesterday evening the adapter was not working.

may it be a hardware issue ?

Caution - 1809 was pulled by Microsoft yesterday.
