[SOLVED] Network controller (Realtek b852) randomly disconnects

Hello everyone!
I recently installed Arch on my Laptop (Lenovo ThinkPad E15 Gen 4) alongside Linux Mint (although I don't really use Mint anymore), so I am still a newbie.
I am using NetworkManager and it works fine, however my WiFi connection randomly stops.
After the connection stops, the Network controller doesn't show up on lspci anymore. Additionally, the wifi device doesn't show up in nmcli anymore. The Network controller uses the rtw89_8852be driver.
I think this has something to do with the "deauthenticating from ... by local choice (Reason: 3=DEAUTH_LEAVING)" message in the dmesg below, but I have no clue what exactly is going on.
Sometimes this doesn't happen for several hours and sometimes it happens about every 30 mins. Does anyone know how i can prevent this?

Here are the outputs of some commands:

lspci -v (before problem occurs):

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

Check and make sure you do not have more than one (1) network service running: stop all other services that conflict with NetworkManager such as systemd-networkd.service.

Check and/or post your journal (journalctl -b) from a boot where the problem occurred.

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

Assuming you are indeed exclusively using NetworkManagers, sadly realtek devices tend to not have the best drivers/reliability. One thing they can often have problems with is with NetworkManager's MAC randomization, so try turning that off: https://wiki.archlinux.org/title/Networ … domization

I did that and I saw that wpa_supplicant was running. I think this can cause issues, but wpa_supplicant was not running some of the other times when the problem occured, so I assumed it wasn't the problem.

This is the output of journalctll -b:

I don't understand what this says, but it seems that wpa_supplicant did something before it broke. I'm just going to disable it and see if that makes things better.

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

Ok, so masking wpa_supplicant just stopped me from being able to use WiFi entirely. Turns out that NetworkManager needs wpa_supplicant.

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

wpa_supplicant gets invoked by NetworkManager and it's always the same PID so that will generally be normal and expected.

You get a bunch of crashes in the driver module though.Try disabling the MAC randomization as suggested, and maybe give https://aur.archlinux.org/packages/rtw89-dkms-git a shot, but you'd have to blacklist rtw89_8852be for those to work properly.

Ok I did this in NetworkManager's config:

wifi.scan-rand-mac-address=no
wifi.cloned-mac-address=stable

If that doesn't change anything I will install the dkms driver.

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

I am far more concerned about the fact that the controller is vanishing from lspci.   Seems to me that falling of the bus should trump all talk of drivers and NetworkManager.

Can we verify that is true?  When it disappears, what does it take to get it back?  Does it 'just' show up again? Or does it take a reboot?  Or does it take a power cycle?

You could also try to pass pcie_aspm=off to the kernel, but

I severely doubt that does anything.

It takes a reboot. However since disabling MAC randomization everything has been working fine. Maybe it is just a coincidence, so I am just going to wait for a bit before changing this topic to solved.

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

It happened again. Unfortunately I immediately rebooted and forgot to print out the journal entry to see if there was anything different going on. I'll do so the next time.

I installed iw and I'll do that manually after booting to see if it resolves the issue.

Can you please also post the modinfo output (so I won't have to install the module just to see whether it offers any power related parameters)?

that's w/ "set power_save off"?

I'm pretty sure that is is, but maybe I made a mistake. Anyway, the error certainly occurred again when I had power_save off.

Btw, I am sorry for answering so late. I don't always have the time/determination to work on those kinds of problems. However, I will solve this issue and when I do, I will update this Thread.

I will change the kernel parameters next and see what happens.

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

Ok I have another question:

I appended rtw_89_pci.disable_aspm_l1=Y rtw89_pci.disable_aspm_l1ss=Y to the "linux" line in the GRUB menu, however I cannot confirm, that these kernel parameters have actually been set. modinfo has not changed and sysctl -a does not show any sign of the parameter.
Does this mean that the kernel parameters have not changed or are they just not being given out by those commands?

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

"rtw_89_pci" is wrong and 

systool -vm rtw89_pci

will hopefully tell you what's actually applied

Re: [SOLVED] Network controller (Realtek b852) randomly disconnects

Ok this issue is solved now.

The solution was to change the Kernel parameters.
