Surface Pro and Network Adapters

I own a Microsoft Surface Pro and have had good luck with it for approximately 2 years.   I am not sure if an update is causing the problem or there is a problem with my Microsoft updates or network drivers, but periodically my network adapters just disappear.  When I click into the network adapter folder, all of my adapters are gone.   I have to restore my system to a previous state with system restore.

Is there a problem with my Surface that I should be concerned about?  I have been lucky and able to restore to a previous state, but what if I do not have that option.   What could be wrong with my system?

There have been dozens and dozens of Windows 8 Updates in the past couple of months. Can you find the manufacturer of your Surface and then get driver updates (BIOS, Chipset, and network cards).

if restoring to the previous state can let you see the adapter again and the adapter can work again, it should not be a hardware failure.

i would first try checking if it is a driver issue then investigate if any newly installed apps could cause the problem.

You may want to also deep scan your computer for malware in addition to updating your drivers

The manufacture is Microsoft and the network adapter is a Marvell AVASTAR 350N Wireless Network Controller.  The driver date is 05/23/14 and the version is 14.69.24054.176.

I use my surface for viewing on-line training's and checking e-mail.  I have downloaded only 4 apps for my surface and the last app installation was over 2 months ago.   I checked the internet and found that I have the latest driver.

After some sleuthing, I found that Windows Defender downloaded and installed 4 definitions about 11:00am this morning.  I noticed the adapter disappearance around 4:00pm this afternoon.  I did perform a threat and malware check with Windows Defender and found nothing.  

My biggest fear is that one of these days, I will not be able to restore my network adapters.  

Is there something else, I should look at?

I will suggest creating a backup then.
By the way, windows defender is not enough to protect your computer.
Combination of antivirus and anti spyware/malware is necessary in today's technology age.

Try superantispyware or malwarebytes.

I'm not sure if you've heard about malware embedded in some brand new hard drives. You may want to google that up

If you are sure the driver is the most recent driver and your updates are to date, consider viruses and malware as suggested above. Scan with your own application and then with Malwarebytes.

Try running System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete, shut down and then restart.

If SFC does not work, run DISM:

Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.

The step after DISM is a Windows 8 Refresh from Action Center, Recovery options. Refresh keeps data and most settings but makes you reinstall software.
