Killer® Wi-Fi 6 AX1650i 160MHz Wireless Network Adapter (201NGW)

[CrisMach]

Hello. This driver installed automatically on my laptop a few weeks ago. From that moment my wi fi connection stopped working and I can t connect to the internet through wi fi,only direct connection by cable. On system manager shows that the driver doesn t start (work). What can I do to establish my wi fi again?

It looks like to need to do a clean reinstall of the drivers. Here is my process for doing so:

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. Now, these drivers are for the AX201. If you have the AX1650i, then you need to use the Killer Wireless package in place of the Wireless driver listed above. This package is available here: https://www.intel.com/content/www/us/en/download/19779. 
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 Wi-Fi 6 AX201/AX1650i 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 Wi-Fi 6 AX201/AX1650i 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.

Hope this helps,
