Surface Book 2 Marvell AVASTAR Wifi/Bluetooth adapter does not start

Question

Error message: "This device cannot start. (Code 10){Operation Failed}The requested operation was unsuccessful."

Bought the surface book 2 second hand a year and a half ago. When I bought it I tested it extensively and everything worked. I then tried a fresh install and panic! wifi didn't work! Marvell AVASTAR Wifi/Bluetooth adapter did not start. But after playing around with driversluckily it all worked again (not sure what exactly I did but wasn't excessively hard, like install some drivers via usb). After that it worked flawlessly for more than a year.

After that year (this summer) the same thing happened again, maybe after a driver or windows update caused it? "This device cannot start. (Code 10){Operation Failed}The requested operation was unsuccessful.".
Was more of a problem this time, played around a lot with uninstalling drivers, installing the whole surface book 2 driver package, disabling 5g... but then it worked again!
This time I thought I would at least keep the driver that made it work on a usb for the next time because it now happened twice, but didn't write down exactly what i did (v15.68.9125.57).

Then 7/10/2021 ago it started again. Of course playing around with drivers again, this time couldn't get it to work with the same driver, also tried others etc.
ONE TIME IT STARTED TO WORK AGAIN and used it all evening! but after I hibernated the laptop and woke it up the next morning it stopped working! And never managed to reproduce.
Now whatever I do I just cannot get it to work again... I tried everything so many times.

I now have 166 events in the event viewer log for the device manager marvell avastar wireless-ac network controller in just this week, that's how many times I tried deleting/reinstalling/etc.
Things I've tried so far:

• Did the network troubleshooting wizard and followed the recommendation to do a 'complete network reset' whatever that means
• Disabling device in device manager and starting again
• keeping only the bluetooth or only the wifi part enabled
• turning off 5 Ghz in the device manager.
• turning off 2.4 Ghz in the device manager.
• Delete device & driver from device manager, restart, install any of these drivers:
  v15.68.9120.47 (rightclick and install mrvlpcie8897.inf)
  v15.68.9125.57 (rightclick and install mrvlpcie8897.inf)
  v15.68.17018.116 (rightclick and install mbtr8897w81x64.inf and mrvlpcie8897.inf)
  15.68.17021.121 newest driver via windows update
  Complete Surface book driver pack SurfaceBook2_Win10_18362_21.064.42912.0.msi
• Delete device & driver from device manager, not restart, install any of those drivers mentioned above.
• Delete device & driver from device manager, manually delete c:\windows\system32\drivers\mrvlpcie8897.sys, restart, install any of those (windows didn't allow me to delete c:\windows\system32\drivers\vwifibus.sys and also not sure if it would do any good so didn't try going around to dos to do it)
• Uninstalled my VPN and did all the things above again (in case their fake adapter would conflict).
• combinations of the above.
• I'm using it on net power

But still it must be a driver issue because the problem occurred twice before and after playing around with drivers it worked well without flaw for a long time. Or could it be a phyiscal problem anyway?

Do you have any trick to permanently erase any trace of the driver from windows before reinstalling another driver version? Any other drivers I could give a go? Any ideas on what's left to try? Any help would be much appreciated.

I already looked into physically replacing it but that seems to be quite difficult for the novice.

I really don't want to permanently have some **** blinking usb wifi card in my usb drive of my fancy beast of a laptop... Prefer also not to try reinstalling windows as it would be a **** of work and I had the same problem the first time AFTER i reinstalled windows so unlikely to do any good?!

Hi Anonymous123_975,

Thank you for reaching Microsoft Community.

Please try to boot the device to its UEFI screen. See this page for the steps in getting to the UEFI settings: How to use Surface UEFI (microsoft.com). Once you are on the UEFI page, go to Devices then check if Bluetooth and Wi-Fi is enabled. If it is already enabled, disable it first then select Exit > Restart now. After restart, boot back to the UEFI settings to enable it back then check if the issue persist.
