in my brand-new Lenovo Thinkpad E495 notebook, I have replaced the (unreliable) Realtek Wifi module with an Intel AX200 card.
However, after the system boots from a "real" shutdown (via executing shutdown /s /t 0), the notebook does not connect to any wifi network for ~1-2 minutes.
After this time span, the Wifi connects. In the windows event viewer, several error messages of the Intel AX200 driver (netwtw08) are listed, as well as a "device reset".
- Windows 10 is freshly installed with all updates
- Drivers for ax200 are the currently available 21.60.2
- after a "real" shutdown (shutdown /s /t 0) in a command-window and booting the notebook afterwards, the notebook does not connect to any wifi for ~1-2minutes after windows is up and running.
Inside the windows event viewer, the following messages are to be found:
Date: 08/02/2020 20:08:57 6062 - Lso was triggered Date: 08/02/2020 20:08:54 7021 - Connection telemetry fields and analysis usage Date: 08/02/2020 20:07:54 The network interface "Intel(R) Wi-Fi 6 AX200 160MHz" has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets. Reason: The network driver requested that it be reset. This network interface has reset 1 time(s) since it was last initialized. Date: 08/02/2020 20:07:54 Intel(R) Wi-Fi 6 AX200 160MHz : Has determined that the network adapter is not functioning properly.

- Afterwards, the wifi comes up and is running reliably (no connection loss etc.)
- after a "normal" shutdown via start menu (i.e. with hibernation), this problem does not occur and the wifi is up immediately.
What I have already tried to track down the problem or resolve it - however without any success:
- Install AMD Ryzen notebook drivers
- Use older AX200 driver
- Change boot option in BIOS/UEFI to "diagnostic" instead of "quick"
- deactivate PCI Express Power management
- deactive Wifi power management
- Replace / switch AX200 module with the a different AX200 module from my desktop PC. Result: both AX200 work flawlessly in my desktop machine.
Is anyone experiencing similar issues? Maybe with a different Intel wifi module?
Could it be that the problem is linked to the Ryzen platform?
I am grateful for any help on resolving this.
Thank you very much in advance!
Regardless, Lenovo is your support provider. You paid Lenovo for support.
There are any number of things that could be wrong - bios update, windows version, shovelware, anti-virus, etc.
Hence, you need Lenovo to sort this out.
