All-in-one Pavillion PC Wireless Driver doesn't work

[LKKKKKKKKKKK]

This is really driving me crazy. Please kindly advise.................

I tried so many times downloading the wireless driver and installing it but this PC never allows the Realtek wireless adapter driver to be installed. I can't install the driver that there is no way to update or whatever HP diagnostics cuz it only detects the ethernet. I did the factory reset my pc and re install the window11 but still the driver doesn't show up after the installation. I tried to install in manually again, but it didn't work. Really have no idea..

Hi Banhien, I did reinstall several times already. The driver installation itself somehow didn't work in my pc.

I tried many times uninstall-reboot &reinstall-reboot.
Few times the driver was successfully installed and I was able to see it under "Device manager" but wifi got disconnected after 2-3 minutes and suddenly the installed driver disappeared in my PC again. This is really ridiculous and frustrating.

Is their any possibility that window 11 has issues?  or is there any other reasons you can think of?
