Stuck with code 56 again

Well, after some automatic Windows update ran yesterday, my AC-9560 stopped to work again, giving the error code 56 (check my previous post in https://community.intel.com/t5/Wireless/Code-56-after-installing-newest-driver-for-AC-9560/)

I'm attaching the SSU information in this message.

The Windows update has likely screwed up the drivers. Use this process to do a clean install:

  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://downloadcenter.intel.com/download/29902 and https://downloadcenter.intel.com/download/29919.
  2. Disable Internet access. Unplug Ethernet cable and/or disable wireless. Keep disabled until told to re-enable.
  3. From Apps & Features, check for instances of Intel PROSet/Wireless Software and Intel Wireless Bluetooth. If none, skip to step 6.
  4. Uninstall each instance present. When prompted, choose to "Discard Settings". 
  5. Manually reboot your computer.
  6. In Device Manager, check Network Adapters for an entry for Intel Dual-Band Wireless-AC 9560. If none, go to Step 9.
  7. Right click on the entry for Intel Dual-Band Wireless-AC 9560 and uninstall it, choosing to (checkmark) Delete the driver software for this device.
  8. Go to Step 5.
  9. (Optional but recommended) Clean out all temporary files using the Windows Clean Disk tool. I recommend that you checkmark all categories offered, even if no files currently (so it leaves it set up for next invocation).
  10. (Optional but recommended) Clear each of your browsers' cache.
  11. Install the Bluetooth driver package (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,
