For those having Wifi issues after the update to Creators edition, please use the following steps to resolve the issue.

In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.

In Device Manager, select Network adapters > the network adapter name.

Press and hold (or right-click) the network adapter, and then select Properties.

I posted this 7 days ago in other section. Best thing to do BEFORE the creator update is archive all your drivers.



I tried the Broadcom device rollback for my new Protocol X8, but that option was "greyed out" and thus unavailable.  The tablet had Internet before the updates were installed, but is now unuseable on the Internet.  Am I out of options?  

Download the drivers from the solutions page.  Unzip and transfer drivers via USB to the tablet.  Use the Update Drivers and select Browse My Computer for Drivers.  Select the location you transferred the drivers to and then click Let Me Pick From a List.  Select the driver dated 7/9.2015.

After the driver is installed, your WiFi should work again. 


ok we had the same problem with ours  too... but the sound  has a red mark next to it... any  help  for  sound?

will the  next time i  look  for updates eat driver again

yep get the sound driver too..



Yep   did  so and all is  well now!  I  just  hope the next update  does not put the evil drivers back!


It is critical to ensure there are zero issues with the remote system related equipment. You have to check the equipment first on the off chance that you dawdle on different futile Windows designs or activities on your Windows 10 Fall Creators Update/Creators Update PC and another information if you need any types of information and fixes then you should visit us on the how to connect Telstra Wifi.

Thank you once again.

Windows 10 upgrade blew away my desktop, network / wi-fi connection, sound and other functions.   Microsoft techs  are working to resolve but at this point have formatted main drive partition and reinistallation of windows 10 has failed to establish functionality.

Re network, I downloaded and transferred the WI-Fi folder to ProtcalX8 via usb stick. Get message Windows Driver is best driver, there is no option for loading the Hyundai Drivers.

When i run network trouble shooter it says there is an error  with network adapter driver.

I cold use any suggestions on how to get the network drivers and "all" the drivers in stalled on this now clean install.   Thanks

RE Network:   Hardware ID  SD\VID_02D0&PID_A94D&FN_1

When in device manager and running  update driver - have disk,  both bbcmfn2 and bcmdh64 creates error message , location does not contain a compatible software driver.

When I right click, install  bcmdh64 directly fron unziped file, program returns a message installed successfully.

When I right click, install  bbcmfn2  directly fron unzipped file, program does not return any message regarding  completion.

Same results with Broadcom  801 adapter installed , disabled or uninstalled.

I ran Bcmwlanappe.exe from wifi unzipped folder and it returns  message , cannot proceed because  MSVCR120.dll was not found.

Cannot find driver match at

I have the same problem with my protocal8 and I fixed the missing msvcr120.dll file

and I installed the drivers recommended - bcmdh64 and bbcmfn2

Still not working - it recognizes available wi fi after I uninstall broadcom adapter and then scan for hardware changes every time.  BUT it always says can't connect to this network. I tried it at home and at starbucks while my phone had no problem connecting.

and it always has a yellow triangle for the virtual adapter (which isn't even there half the time).

When i restart, the wifi once again has the red asterisk.


i'm going to try the flash for windows 1703 image recovery

I have no confidence since everything thus far has failed.even Ron Kuzma in above comments said he had a clean install of windows and still couldn't get wifi

I'l post my results

 Mine is working fine, you have a driver mismatch somewhere.

The wifi driver is Broadcom

The other drivers are likewise important:

The GPIO virtual controller is Intel 604.10135.1000.55535

The I2C controller is Intel 604.10143.1010.2069

The GPIO controller is Inter 604.10135.1010.53001

Those are the most important ones I have found.
