Wifi fully updated and will not work after windows 10 update

This morning my computer updated its windows 10 and immediately the wifi connection no longer worked. All other devices run fine, so I checked the manager on my computer and sure enough there is an exclamation point in a triangle next to intel wi-fi ax200 160MHz. The device cannot start. I have updated everything from Windows, to HP, to Intel software and there are no fixes so far. I have uninstalled and reinstalled with no fix. Does anyone have an idea of what to do next before I toss this thing out the window? Thanks.

Sadly, this is happening more and more often. Microsoft is screwing up the driver configuration during the update process.

The only solution, AFAIK, is to do a clean install of the Wireless and Bluetooth drivers. Here is my process for this operation:

  1. If you haven't already, download - but do not install just yet - the latest Bluetooth and WiFi drivers for your adapter. Here are links to these  drivers: https://www.intel.com/content/www/us/en/download/19351/windows-10-wi-fi-drivers-for-intel-wireless-a... and https://www.intel.com/content/www/us/en/download/18649/intel-wireless-bluetooth-for-windows-10.html. 
  2. Disable Internet access. Unplug Ethernet cable and/or disable wireless. Keep disabled until told to re-enable.
  3. From the Apps & Features applet, check for instances of Intel PROSet/Wireless Software and Intel Wireless Bluetooth. If none, skip to Step 6.
  4. Uninstall each instance of Intel PROSet/Wireless Software and Intel Wireless Bluetooth that is present. When prompted, choose to "Discard Settings".
  5. Manually reboot your computer, keeping Internet access disabled throughout.
  6. From the Device Manager applet, check the Network Adapters section for an entry for Intel Wi-Fi 6 AX200 and check the Bluetooth section for an entry for Intel Wireless Bluetooth that has an intel driver associated with it. If neither is the case, go to Step 10.
  7. Right click on the entry for Intel Wi-Fi 6 AX200 and uninstall it, choosing to (checkmark) Delete the driver software for this device.
  8. Right click on the entry for Intel Wireless Bluetooth and open its properties. If it has an Intel driver associated with it, then uninstall it, choosing to (checkmark) Delete the driver software for this device.
  9. Go to Step 5.
  10. (Optional but recommended) Clean out all temporary files using the Windows Clean Disk tool. Ensure you have enabled cleaning of System Files. I recommend that you then checkmark all categories offered, even if no files currently in this category (so it leaves it set up for next invocation). (Optional but recommended) Clear each of your browsers' cache.
  11. Install the Bluetooth driver package (my rule: always do Bluetooth first).
  12. Install the Wireless driver package.
  13. Manually shutdown and reboot your computer.
  14. Enable Internet access.
  15. Test.

Hope this helps,

Thanks! These steps worked and I am now connected wirelessly once again! Although, I skipped step 10 because I couldn't find my Windows Clean Disk tool. Otherwise, I followed all these steps and it fixed the problem.

The executable for the Disk Cleanup applet is here: c:\windows\system32\cleanmgr.exe. Using the search box, just type in 'cleanmgr' and it should find and invoke it. I recommend running this tool weekly.
