Windows 10: Qualcomm Wifi Adapter problems on 802.11r WLANs after KBKB5032288 update

Dear Microsoft,I'm a local IT guy at an university in Belgium and we had 4 students with exactly the same problem after this update. They can't connect to our wifi-network. Only a removal of this windows update fixes the problem at the moment.All the wifi adapters are Qualcomm ones.We have two wifi networks one that has 802.11r Fast BSS transition enabled and one where it is disabled. The students only have this problem on the enabled Fast BSS Transition wifi network.I've also heard that two other universities, one in the Netherlands have exactly the same problems with the Qualcomm Adapters

Problems when sharing WiFi with the Virtual Adapter

For many years I have always shared Internet to my devices like phone and tablet with my PC's WiFi antenna through the Microsoft Wi-Fi Direct Virtual Adapter, I only use it for that, since I have a cable connection, and I start the wifi with the command NETSH WLAN start hostednetwork previously having done the settings of NETSH WLAN set hostednetwork mode=allow ssid="Wifi" key="password".

For my devices to connect it is necessary that the Virtual Adapter that is created with that command has access to the Internet, for this I have to share the Internet from my Ethernet adapter to the Virtual Wifi adapter.

For some time now (a couple of months) I've been experiencing problems when sharing the Internet through that medium. The problem is that when I start the WiFi my devices do not connect, they say "Getting IP address" and never connect.

I have found the solution and I have to do the following:

1. Disable the Virtual Adapter with the command netsh wlan stop hostednetwork.
2. Remove the connection sharing from the Ethernet Adapter.
3. Activate the Virtual Adapter with the command netsh wlan start hostednetwork.
4. Adding connection sharing from the Ethernet Adapter to the Virtual Adapter again.

By doing these steps my devices can now be connected to the Wifi, but sometimes it doesn't work if I do these steps too quickly. I have noticed that if I do step 3 and 4 too quickly it does not work and I have to repeat the process but doing these last two steps more slowly, until the Virtual Adapter gets an IP address 192.168.137.1 from Internet Protocol version 4

Also this problem does not occur 100% of the time. Sometimes when I run the command to start the Wifi everything happens fine and my devices connect well but this only works after my PC has been on for at least 5 minutes (I haven't counted it). If I run the command as soon as my PC has turned on then it doesn't work anymore.

As I mentioned before this problem didn't occur before because I had configured a .bat file that ran as soon as the PC was turned on with the NETSH WLAN start hostednetwork command and everything worked fine.

Now, I would like to go back to before when everything was fine so that when my PC starts up the WiFi too and I don't have to do all this protocol all the time, but with a simple command everything is solved.

Could someone give me a hand with this?

 

Deleted WLAN wifi adapter

Did that step. It says that it had encountered a problem many times so it dosent seem if it can work. But for the installed 2017 WLAN Driver, it doesn't appear in the list

 

WLAN Adapter issues

Hello all,

So i've been having an issue with my WLAN adapter and based on my research it seems this is a common problem after upgrading to Windows 10 (although in my case the upgrade happened many months ago, long before this issue arose).

My wifi connection would randomly die, and the WLAN adapter (Realtek RTL8188EE) would disappear under device manager. Based on my research again I took following steps

1)Updating Drivers (no result)

2)Registry deletion of pre existing VPNS etc (no result, as expected since i've never used a VPN)

A clean install was suggested, so I did that. Some results, although problems still arose albeit less frequently.

After that it was suggested I 'roll back' my drivers, which also had no effect. Then suggested to perform 'network reset' which once again worked off and on. Then suggested to uninstall the adapter and restart. That worked!HOWEVER since I wasn't 100% sure
how to backup my files and all again so I had created a system image. Upon restoring a system image of my computer from before the clean install, the issue arose again. So I REperformed the clean install, this time relying on the 'keep personal files only'
aspect of the install. Unfortunately, the same problems arose again. so I took the same steps. HERE IS WHERE my current problem lies and I need help.

So to fix the issue again, I did the network reset, which didn't work. Then I uninstalled the adapter and restarted my computer...and now it won't show up. At all! No matter what I do, the WLAN adapter has disappeared from device manager, and I do not know
how to get it back!! I can't install new/updated drivers manually, because there's nothing there to install to!

Is there any way I can get my adapter back online, or will I have to perform the clean install again ?

I apologise if perhaps i'm not describing some of my steps/problems super clearly, i'm not very good at this sort of thing...
