Windows 10: Realtek RTL8811BU Wireless LAN 802.11ac USB NIC - WIFI PROBLEM - w10 64

I have a Realtek RTL8811BU Wireless LAN 802.11ac USB NIC, which is in the 3.0 port - different from TimScharf https://answers.microsoft.com/en-us...s/8788d23c-c1ed-4c8c-be1b-8333f9105b0b?page=3 - but I experienced the same problems as him.
I try the sollution proposed by Corey Ford same link above - to put "not support QoS", which solves the disconnection trouble, but as others I have huge drop in speed.
Then I see the post of SteveNPhx same link above. Mine driver wasn't with Microsoft in driver provider - it was Realtek - but I see in device manager the realtek device and another microsoft wifi adapter too.
Then, as SteveNPhx said, I put windows updates for drivers NO. Then I uninstall realtek wireless device in device manager; uninstall realtek lan driver and the windows wifi adapter too and reboot. When system comes up I see that windows doesn't uninstall nothing.
Then I uninstall again and pin out the device from usb and reboot. After that, I plug the device to USB and install the driver from realtek site same as in the CD and it works!! - without having to change QoS is in support as default.
For my surprise, in the driver description said Realtek RTL8811BU Wireless LAN 802.11ac USB NIC, bit driver provider: Microsoft, data: 25/10/2018; version: 1030.27.425.2018; digital signature: Microsoft.
So, I think that what solves in my case is just to put windows updates for drivers NO, before installing the device, which is preventing windows to put another driver and cause some conflict. Is problably a realtek driver problem with that windows function.

Realtek 8812BU USB Wireless LAN Fails After KB4522355

These generic steps have nothing to do with my problem.

I've reloaded the driver both from Windows Update and from the MFG several times. It seems that KB4522355 has made my Realtek 8812BU Wireless LAN 802.11ac USB NIC incompatible with Windows.

It seems like instead of random MVP answers someone from Microsoft would offer some specific help.

 

How do i solve code 39?

I bought a Realtek RTL8811AU Wireless Lan 802. 11ac USB 2.0

it says code 39 Cant load devicedriver for this software.

Ive tryed too update it but its already installed.

 

After the July 15, 2016 my wifi card disappeared.

I have gone back to last week's restore point, but the network adaptor is still "not connected." Something about the crash that occurred after the windows update seems to have convinced the computer that the network adaptor is disconnected, but that seems
unlikely since nothing moved and this is an internal adaptor (Realtek 8821AE Wireless LAN 802. 11ac PCI-E NIC)
