Realtek 8852BE driver missing even though it should be available

Question

I have an HP laptop with an Realtek 8852BE wifi card, and I am unable to use the driver even though the driver for it is supposed to be included in the kernel after 5.16+ as per lwfinger README.md.

How can I use the driver available in the kernel assuming it is actually available?

Currently I am using this driver, but it is deprecated: https://github.com/HRex39/rtl8852be

I had also tried this driver, but it was unstable: https://github.com/lwfinger/rtw89

Running sudo lshw -C network returns:

Running uname -r returns: 5.19.0-35-generic

I don't know how to see if the driver is available, so I tried to figure out if the module is available using the command below.

Running modprobe -D rtw_8852ae returns:

modprobe: FATAL: Module rtw_8852ae not found in directory /lib/modules/5.19.0-35-generic

Running modprobe -D rtw_core returns:

modprobe: FATAL: Module rtw_core not found in directory /lib/modules/5.19.0-35-generic

Edit: The HRex39 driver is working at least for now, but since it's deprecated, I wanted to switch to the kernel provided driver. The only annoying thing is that I have to recompile it for every kernel update.

The OS is Ubuntu 22.04.2 LTS

Edit 2: I have executed the diagnosis script, but I don't see anything that could point me to the cause of the issue. All I see is the iwlwifi being removed, but as far as I know that is only for intel wifi. Details: I had unloaded the module with modprobe -rv 8852be which returned:

rmmod 8852be
rmmod cfg80211

Then rebooted... after which it turns out that the driver was loaded again, so I had removed it once more with modprobe -rv 8852be then blacklisted it using: echo "blacklist 8852be" >> /etc/modprobe.d/local-dontload.conf. I rebooted again and this time I no longed had wifi.

I also tried loading both of the following two modules but to no effect: modprobe mac80211 and modprobe cfg80211

Running the script from: https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info returns:

Edit 3: After searching trough the rtw89 commits it looks to me like it is included in the 6.1 kernel. Specifically this merge I would say it adds the 8852BE driver.

Did I understand correctly in which version it is available?
Assuming this is true, should I expect the driver to be available when Ubuntu will include the 6.1 kernel?

The driver version you are showing there that is loaded does not match the GIT repo you have shared. Git is showing v1.15.6.0.2-0-gac110bf5.20211029 and yours is showing v1.15.6.0.2-0-gac110bf5.2021102 which is showing a newer driver has been loaded. — Terrance, Mar 10 '23 at 01:20
Does this answer your question? My wireless/WiFi connection does not work. What information is needed to diagnose the issue? — waltinator, Mar 10 '23 at 07:15
@Pilot6 Yes, but my questions are:

Is the driver available in the kernel?

If yes, how can I use the driver from the kernel, instead of the 8852be since it's deprecated. I had blacklisted the driver so that I can try to use the kernel driver — Mihai Buba, Mar 10 '23 at 14:54
Do you know where I can monitor to see when it will be available? — Mihai Buba, Mar 10 '23 at 16:06
