My issue is pretty similar to #226 and #240. I have used AUR to install the latest version and tested with or without modifying /usr/lib/modprobe.d/70-rtw89.conf

options rtw89_pci disable_clkreq=y disable_aspm_l1=y disable_aspm_l1ss=y
options rtw89pci disable_clkreq=y disable_aspm_l1=y disable_aspm_l1ss=y

while still the wlan reported errors after using a certain period of time

I have to reload rtw module to make interface work again. I also tested with the mainline kernel but I got the same errors.
I read that it is caused by some buggying BIOS settings while I didn't find options that relate to low power PCI or something else :(. I have been experiencing this months though I can used wired connection :p. I wonder if I did anything wrong.

Here is my module files

First of all, do a 'git pull' as there have been recent changes.

If that still fails, modify /usr/lib/modprobe.d/70-rtw89.conf and add these two lines:
options rtw89_core disable_ps_mode=y
options rtw89core disable_ps_mode=y

The late model HP and Lenovo laptops have been a lot of trouble as their BIOS seems to be exceptionly buggy.

I've a Lenovo Ideapad 5 15ABA7 and using Linux 6.5.5 with the official drivers I've to add

options rtw89_pci disable_aspm_l1=y disable_aspm_l1ss=y

to not get broken wifi after some network traffic until next reboot
and

options rtw89_core disable_ps_mode=y

for the bluetooth part. Without it my BT mouse is often laggy and from time to time a BT scan doesn't find anything any longer until reboot.

The disable_clkreq=y is not needed with my Ideapad 5.

@lwfinger Do you know if there will be more fixes to the official kernel to get the hardware to work without the driver options? And is it possible for you to give a more detailed explanation what might be the problem with the Realtek hardware in Lenovo devices? Thx

[kolbma]

Ah, and you need at least firmware version 0.29.29.3.
The older 0.29.29.1 also doesn't work with the driver options added.

[lwfinger]

The problem is not with the driver. It is your BIOS that requires the options for rtw89_core. That will probably NEVER be fixed by Lenovo as they have had this problem for at least 2 years. The bottom line is that your BIOS does not conform the the PCIe standards. The Windows driver obviously does a work-around similar to the options used for the core routine.

Realtek is working on the problems with BT while power-saving is enabled. I have not heard of any progress.

Ah, and you need at least firmware version 0.29.29.3. The older 0.29.29.1 also doesn't work with the driver options added.

Hey, how can I upgrade the firmware? I have git clone and manually installed the latest driver but the firmware number is still 0.29.29.1.

[lwfinger]

For most people, te firmware updates are provided by their distro. If yours does not, then you will need to obtain it from some other location. THIS REPO DOES NOT PROVIDE FIRMWARE, AND NEVER WILL.

You can get a tarball of the latest firmware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20230919.tar.gz. Unpack that and copy the files in the rtw89 directory into /lib/firmware/rtw89/.

You really ought to consider a distro that keeps you up to date!
