Apple BootCamp WiFi Driver update as well as bluetooth driver both not working

Hi TT. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

You can remove and block any driver or other Windows Updates that cause problems as shown here:
https://www.howtogeek.com/223864/how-to-uninstall-and-block-updates-and-drivers-on-windows-10/

You can also System Restore to a point before the problem began following this guide:  http://home.bt.com/tech-gadgets/computing/how-to-fix-windows-10-problems-with-system-restore-11364008291943

You can System Restore from Repair Mode if it will not work in Windows, following one of these paths:  https://www.tenforums.com/tutorials/2294-advanced-startup-options-boot-windows-10-a.html

You can get Windows Drivers on Mac this way:

WIFI FIXES -

I'll give you everything that works to fix Wifi so that at least something will work:

Update your network adapter drivers from the PC maker's Support Downloads web page using the full model number, HP Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

If you have the latest network driver then try on it's Driver tab also to Roll Back, or Uninstall and then restart PC to reinstall the driver. Try also all older drivers from Update Driver > Browse > Let Me Pick list working backwards.

If this was caused by Windows Updates then you can check which were installed at Settings>Update & Security>Windows Update under Installed Updates, then uninstall them from the link there, and hide with the Hide Updates tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them: http://home.bt.com/tech-gadgets/computing/how-t...

If this was caused by Version update then you can roll it back in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

For Wifi won't connect after Version 1903:

https://pureinfotech.com/fix-wifi-problems-wind...

Enable IPv6 in the network adapter settings: https://www.tenforums.com/tutorials/90033-enabl...

Run the fixit from https://support.microsoft.com/help/929852 (Re-enable IPv6 on all nontunnel interfaces) and reboot.

Right click the network icon in System Tray at bottom right end of task bar to Troubleshoot Problems.

Try all of these steps: https://support.microsoft.com/en-us/help/10741/...
https://www.kapilarya.com/how-to-reset-network-...

Go to Settings > Network & Internet > WIfi > Manage Known Networks, highlight and remove the network having problems, restart PC to see if it shows up again.

Try plugging in by ethernet cable to the router to compare, then plug the ethernet cable into the modem (if separate) to see if this might be an issue with the router.

Try powering off modem, router and PC and then restarting in that order with 1 minute in between each. You may need to reset your router or even optimize it following these steps:
https://www.lifewire.com/resetting-a-home-netwo...
http://www.maximumpc.com/article/features/ultim...
Your router manual is always available from the manufacturer's website for your exact model.

You also are entitled to Support from your internet provider to get online on all devices. This is always included in the monthly bill. If your router is less than a year old they will also Support getting it connected and optimized.

Another option is you could replace the wireless adapter with an inexpensive USB nano adapter like this one: https://www.amazon.com/TP-Link-wireless-network...

You can also add an extender. The best one I've found is $17 at Amazon, configures itself, and so good I'd never use any other: https://www.amazon.com/TP-Link-Extender-Externa... 

BLUETOOTH FIXES -

 I'll give all possible steps for troubleshooting Bluetooth in order of priority.  Many problems right now are being solved by updating to the latest version so if you want to skip to that step see the Repair Install at bottom:

Try Updating the Bluetooth driver from the PC maker's Support Downloads webpage for your exact model.  Install it even if it's the same or newer than the one in Device Manager reached by right clicking the Start button.

Right click Start button to access Device Manager, locate Bluetooth device (if necessary from View tab Show Hidden Devices), on Driver tab see if Roll Back is available, if not try Update Driver, first automatically, then Browse, then Let Me Pick to try all previously installed Drivers. 

If these fail Uninstall the Driver, restart PC to reinstall.  If the BT driver is not there, access the View tab in Device Manager to "Show Hidden Devices."

Make sure you're pairing correctly as shown here:  https://support.microsoft.com/en-us/help/15290/windows-connect-bluetooth-device

 See Fixes here which are all working: 
https://support.microsoft.com/en-us/help/14169/windows-10-fix-bluetooth-problems
https://superuser.com/questions/1017867/make-windows-10-recognize-bluetooth-dongle-as-bluetooth
https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware-winpc/bluetooth-not-working-cant-find-in-device-manager/ccfa2f34-ac5e-4718-b499-e6050e511a41

Try the Bluetooth troubleshooter at Settings > Update & Security > Troubleshoot. 

Try turning off Fast Startup at Settings > System > Power & Sleep > Additional Power Settings > Choose what Power buttons do > Change settings that are unavailable > uncheck Fast Startup. 

If this is a mic or headset right click Volume icon in System Tray to Open Sound Settings,  make sure the correct device is selected for input or output in the dropdown menu. 

Then try pairing again, if necessary run the Bluetooth Troubleshooter again. 

 If this was caused by Windows Updates then you can check which were installed at Settings>Update & Security>Windows Update under Installed Updates, then uninstall them from the link there, and hide with the Hide Updates tool downloaded from here:  http://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagcab

You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them:  http://home.bt.com/tech-gadgets/computing/how-to-fix-windows-10-problems-with-system-restore-11364008291943

If this was caused by a Version Update then for 10 days you can roll it back in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool which is explained more here:  
https://www.howtogeek.com/223864/how-to-uninstall-and-block-updates-and-drivers-on-windows-10/.
 
If you think the BT adapter has failed, you can replace it easily with a USB nano adapter like this one:   https://www.amazon.com/ZEXMTE-Bluetooth-Receiver-Transfer-Wireless/dp/B0775YF36R/ref=bmx_1/144-8846981-0178846?_encoding=UTF8&pd_rd_i=B0775YF36R&pd_rd_r=fc7fb64f-ee89-4d01-949a-cce053b97603&pd_rd_w=re3cN&pd_rd_wg=I4GXx&pf_rd_p=806524e0-5994-4c0d-9d36-11f6132400bc&pf_rd_r=56PQ4YAVKHETB3GJY6BH&psc=1&refRID=56PQ4YAVKHETB3GJY6BH

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:  http://answers.microsoft.com/en-us/windows/wiki/windows_10-performance/windows-10-performance-and-install-integrity/75529fd4-fac7-4653-893a-dd8cd4b4db00

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files.  Then continue with the other steps to go over your install most thoroughly. 

If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now.  This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1909 which you need anyway and by the most stable method.   http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install.  
 
I hope this helps.  Feel free to ask back any questions and let us know how it goes.  I will keep working with you until it's resolved.
