[Ayeball]

Had error on driver 23.80 in device manager. With 23.90 update it was resolved for some minutes , but now its the fault code back. 

Code 31

Port_#0014.Hub_#0004

And my ideas about how to fix it is empty.

First of all, your post is too terse, and we need more information in order to determine anything. Please download and run the Intel System Support Utility for Windows. When you start the utility, select Everything and then click on Scan. Once it completes the scan process, click on Next and then Save. Pick a name for the text file to create and click on Save to create it. You can then close the app. Finally, open a response post here and then, using the Drag and drop here or browse files to attach dialog (below the edit box for the body of your response post), upload and attach this text file to the response post.

Now, the standard guidance that I give for this error is to do a clean install of the drivers. Here is my process for doing this clean install (substitute your adapter for the Wireless-AC 9560 used):

1. If you haven't already, download - but do not install just yet - the latest Bluetooth and Wireless driver packages for your adapter. Here are the current links for downloading these drivers: Wireless: https://www.intel.com/content/www/us/en/download/19351 and Bluetooth: https://www.intel.com/content/www/us/en/download/18649.
2. Most important! Disable Internet access. Unplug Ethernet cable and/or disable wireless. Keep disabled until told to re-enable. Note: This Wireless disable *must* be of type that will persist (i.e. stay disabled) across reboots.
3. From the Apps & Features applet, check for instances of Intel PROSet/Wireless Software and Intel Wireless Bluetooth. If none, skip forward to Step 6.
4. Uninstall each instance of Intel PROSet/Wireless Software and/or 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 Wireless-AC 9560 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, skip forward to Step 12.
7. Right click on the entry for Intel Wireless-AC 9560 and select Uninstall Device. In the dialog that is then presented, choose to (checkmark) Delete the driver software for this device.
8. Repeat step 7 until the option to Delete the driver software for this device is not offered (i.e., is greyed out).
9. 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.
10. Repeat step 9 until the option to Delete the driver software for this device is not offered (i.e., is greyed out).
11. Go back to Step 5.
12. Install the downloaded Bluetooth driver package you downloaded earlier (my rule: always install Bluetooth first).
13. Install the downloaded Wireless driver package you downloaded earlier.
14. Manually shutdown and reboot your computer.
15. Reenable Internet access. Restore Ethernet cable and/or reenable wireless.
16. Test.

Note: It sometimes takes multiple uninstall (and reboot) cycles to clean out the old installations, so don't give up on the process. If you get to, say, 10 cycles, stop there and attempt the installation of the latest drivers.

Now, if this doesn't work, we will need more information in order to help further. Please download and run the Intel System Support Utility for Windows. When you start the utility, select Everything and then click on Scan. Once it completes the scan process, click on Next and then Save. Pick a name for the text file to create and click on Save to create it. You can then close the app. Finally, open a response post here and then, using the Drag and drop here or browse files to attach dialog (below the edit box for the body of your response post), upload and attach this text file to the response post.
