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

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, enter image description here

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, enter image description here

"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?

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.)

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.

Are there any interesting clues? Please edit your question to include the result of: `sudo dmesg | grep rtw`

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`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
