Have you tried doing a clean install? The process to use is as follows:
- 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/30434 and https://downloadcenter.intel.com/download/30515.
- Disable Internet access. Unplug Ethernet cable and/or disable wireless. Keep disabled until told to re-enable.
- From Apps & Features, check for instances of Intel PROSet/Wireless Software and Intel Wireless Bluetooth. If none, skip to step 6.
- Uninstall each instance of Intel PROSet/Wireless Software and Intel Wireless Bluetooth that is present. When prompted, choose to "Discard Settings".
- Manually reboot your computer, keeping Internet access disabled.
- In Device Manager, check Network Adapters for an entry for Intel® Wireless-AC 9560. If none, go to Step 9.
- Right click on the entry for Intel® Wireless-AC 9560 and uninstall it, choosing to (checkmark) Delete the driver software for this device.
- Go to Step 5.
- (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).
- (Optional but recommended) Clear each of your browsers' cache.
- Install the Bluetooth driver package (rule: always do Bluetooth first).
- Install the Wireless driver package.
- Manually shutdown and reboot your computer.
- Enable Internet access.
Hope this helps,
If problems persist, go back to the original set of driver files provided by your laptop manufacturer (should be on their website) and see if this version works as it should (use the same process to install these older versions). If the problem persists with that version, then you need to contact your laptop manufacturer regarding the issue.
