Windows 10: Realtek RTL8812BU Wireless LAN 802.11ac USB NIC - Adapter "dies" after trying to connect

Hello, I recently contracted a new ISP with a new modem/router and my Wi-Fi Adapter can't seem to connect to it can connect just find to the old networks. All my other devices connect to it no problem, and if I use an ethernet cable I can connect too, the only problem is my PC's Wi-Fi adapter. If I try to connect to it, the adapter shows "This device cannot start, error code 10" making it so that I have to reconnect it and try again.


I found this thread https://answers.microsoft.com/en-us...s/8788d23c-c1ed-4c8c-be1b-8333f9105b0b?page=1


In which there's 2 solutions, however these didn't quite work for me.


Solution 1: SteveNPhx's post. Making sure that Realtek is the driver provider instead of Windows. I did this, and I keep having the same issue.


Solution 2: Corey Ford's post. Disabling the option of "Support QoS", now, eventhough this sort of work and makes it so my adapter is able to connect to the network, the speed is seriously decreased to about 10% of what it actually is so it's not really a great option.


I would really appreciate some help fixing this issue. I already tried the "latest driver" both from Windows and one directly downloaded from Realtek's website.

Realtek RTL8812BU Wireless LAN 802.11ac USB NIC - WIFI PROBLEM - w10 64

I have a Realtek RTL8812BU Wireless LAN 802.11ac USB NIC, which is in the 3.0 port - different from TimScharf (Constant Wi-fi problems)
- 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 RTL8812BU Wireless LAN 802.11ac USB NIC, but driver provider: Microsoft, 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 USB Wireless LAN Adapter setup failed.

I have been trying to setup a wireless USB adapter from 2 days but i'm failed. It's a "USB 2.0 Wireless 802.11N" Lan Adapter. When i connect it to computer it's driver showing up to the device manager for a few seconds and then vanish. Sometime the driver
stay up a long time but i can't configure Wifi. When i connected it, in device manager under network adapter it shows "Realtek RTL8188FTV Wireless LAN 802.11n USB 2.0 Network Adapter" some time it comes up with a yellow sign. I'm tried to setting it. My computer
windows version is 10 pro and it is up to date.





it's a picture of 300 Mbps but mine is 600 Mbps.

One more thing when i setup the driver from CD included with the adapter its installed but the problem remain the same.
