WiFi Card crashes every few hours

[albin04]

Hi! I have been enjoying my new HP Pavilion Gaming laptop for a few months now without any problems.
However, recently, there has been a really irritating problem related to WiFi networking. I turn on my laptop
and can use it connected to my WiFi network for a few hours - the time varies but is usually around 2-3 hours.
After that, the WiFi disconnects, and when checking the network settings in the taskbar, it says that the WiFi
is "Not available" - the WiFi menu is completely greyed out. Sometimes, the Bluetooth stops working at around the same time too.
I can solve this by opening the HP Network Control in the HP Support Assistant and running a troubleshoot. It runs every time,
resets the network card, and then the network card starts working again and I can use it for a few more hours until I have to reset it again
using that tool (resetting it via Device Manager does not work). It also works to restart the computer.

Here is what I have tried so far to fix this happening:
1. Updated my Windows using all available updates (both mandatory and optional) from Windows Update
2. Installed all driver updates (including network card updates) from HP Support Assistant
3. Uninstalled all VPN software installed on my computer.
4. Tried with different WiFi networks in two different houses at two different locations - same problem.
5. Used the HP Network troubleshooter in HP Support Assistant - works but the problem comes back (see above)
6. Used the HP PC Hardware Diagnostics and ran all the quick tests. All came back as successful with no error codes.
Test ID 21986-73110-95958.
None of the above has fixed my issue completely.

Detailed system information in case that helps:
Computer: HP Pavilion Gaming Laptop 15-ec2xxx
Windows version: Windows 11 Home 22H2 (22621.755)
Network adapter: Realtek RTL8852AE WiFi 6 802.11ax PCIe Adapter
BIOS version: AMI F.22, 2022-08-10
I have antivirus installed, ESET Internet Security.

Hi:

I don't know what driver version you installed, but the Realtek Wi-Fi drivers on your notebook's support page are not the latest ones.

This is the latest Wi-Fi driver HP has for the Realtek RTL8852AE Wi-Fi adapter:

6001.10.350.0      06/01/2022

https://ftp.hp.com/pub/softpaq/sp142001-142500/sp142328.exe

If you don't have the latest version installed, you may want to give that a try.

That would be the only suggestion I can offer.

Thanks for that tip!  As soon as you replied, I installed those drivers on my computer, and the problem actually disappeared for a couple of days until my computer was automatically updated to the latest Windows version (22621.755). This update also brought an input delay when using keyboard devices (takes around 5 seconds for words I write to appear on the screen), both with my Bluetooth keyboard and the built-in computer keyboard. This irritating error also disappears if I just restart the computer. Mentioning that here in case they are related. What would you suggest checking?
