Manually installed wifi driver for Realtek b852 stops working until restarting the computer

Question

I run Ubuntu 22.04 to a on "hp probook 455 g9". As the wifi wasn't working at first, 7 months ago I asked how to install the wifi driver in the first place, here: Problems with manual installation of a wifi driver for Realtek b852

Few days ago the wifi stopped registering my wifi, even though it was still working just fine on other devices. When I restarted the computer, it got back on, but soon it stopped working again, so now I'm on 20+ restarts a day.

When restarting, this shows up,

I was suggested to look at this post I have a hardware detection problem, what logs do I need to look into? so I'll just post the information:

Any ideas what could help solve this? Thank you for your time!

Edit2: As I'm writing this, wifi's stopped showing up again,

"nmcli device wifi list":

IN-USE  BSSID  SSID  MODE  CHAN  RATE  SIGNAL  BARS  SECURITY

"sudo dmesg | grep wlp": doesn't result in anything.

I looked at https://github.com/HRex39/rtl8852be.git, and if I'm looking correctly, I have kernel > 6.0.0, so maybe that's the problem? If so, would you please tell me how to uninstall rtl8852be, so I can try the rtw89?

Please see your dmesg above. You are already using the built-in rtw89 driver. Do I understand that it works sometimes but then stops? — chili555, Aug 17 '23 at 13:30
Yeah, it just stops some time after booting - could be a minute, could be an hour. (Given the fact that the symptoms remain the same, i was under the impression that i didn't manage to install rtw89, sorry for the confusion.) — laketax, Aug 20 '23 at 04:39

This is the subject of a bug report here: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.1/+bug/2017277

Let’s try the suggested fix, amended slightly.

sudo nano /etc/modprobe.d/rtw89.conf

Add a single new line:

options rtw89_pci disable_clkreq=y disable_aspm_l1=y disable_aspm_l1ss=y

Proofread carefully. Save (Ctl+o followed by Enter) and exit the text editor (Ctrl+x).

Reboot and tell us if there is any improvement.

Thank you for your response! I did what you suggested (hopefully correctly), but sadly the wifi stopped working again. – laketax Aug 14 '23 at 04:00
Are there any interesting clues? Please edit your question to include the result of: sudo dmesg | grep rtw – chili555 Aug 14 '23 at 15:08
Looks perfect to me. Does it see networks? nmcli device wifi list No need to post the whole list; just tell us if networks are seen. Are there clues here? sudo dmesg | grep wlp – chili555 Aug 16 '23 at 13:14
