Garuda (2.5.4-2):
head: cannot open '/var/log/pacman.log' for reading: No such file or directory
System install date:
Last full system update: 2022-02-03
Is partially upgraded:   No
Relevant software:       NetworkManager

I've installed Garuda Linux on my machine and upgraded the system. However, after I reboot, I face a wifi connection problem : the network manager cannot detect my wifi router but only detects my phone if I set it as a mobile hotspot. I've been searching a lot for a fix to this issue and I even reinstalled Garuda so many times but after I reboot I come to face that annoying problem again.

I've tried many solutions provided for such a problem in various websites and forums and none of them did work :

restarting the network manager with sudo systemctl restart NetworkManager

disabling wifi powersave

adding 2 lines as following to /etc/NetworkManager/NetworkManager.conf:



adding 2 lines as following to /etc/NetworkManager/conf.d/nm.conf :



and I runned these commands :

sudo pacman -S iwd

sudo systemctl stop wpa_supplicant

sudo systemctl mask wpa_supplicant

sudo systemctl enable --now iwd.service

sudo systemctl daemon-reload

sudo systemctl start iwd.service

I also restarted my wifi router in vain

So what shall I do now ?

Sometimes when trying some of the mentionned fixes, the network manager detects my wifi router but it cannot connect to it and shows : Authorization supplicant failed

Hi there, welcome.

This is not enough information.

Let's start providing your garuda-inxi as per the new topic template. :wink:


@filo Done

Mmm, nasty device I guess. I normally start searching for the device inside the Networking Support category, but haven-t found real solutions.
You may want to start reading these:
I hope someone will have other advices...



Then reboot and post:

grep -r "blacklist\|install\|options"  /etc/modprobe.d/ /etc/modules-load.d/ /usr/lib/modprobe.d/ 

could you guide me how to install it, as I'm an absolute Arch Linux beginner.

Have you tried booting into windows, then reboot (warm boot) into linux.

paru rtw88-dkms-git

I deleted WIndows, I'm managing to get used to Linux

Was this output above run after installing the driver?

yes, I installed that driver, executed that code with grep that resulted in that output

With a text editor create /etc/modprobe.d/rtl8822be.conf with the following contents:

blacklist rtw88
blacklist rtw_pci


If no love, try changing blacklist rtw_pci to blacklist rtwpci


I tried that in vain
Please help @tbg

Please do not beg for help nor ping team members with @.
It sounds rude, nobody is paid here, and last but not least, consider the time zones...


Sorry but I didn't mean to bother anyone

Ya, sorry buddy, but people got to sleep. I'm on the other side of the world from you.

I would suggest installing the linux-lts kernel, and then reinstall the driver on the LTS kernel.


Also, you will need to check if a bios update is available from your laptop manufacturer. If their is a newer bios, you would be well advised to install it. Having removed Windows this would likely need to be done from a boot disk supporting Windows.

I would advise testing all of the following kernels. You can install kernels through the Garuda GUI for managing your hardware. Also be sure to install the corresponding headers.

This can be done in the terminal:

sudo pacman -Syu linux linux-headers


sudo pacman -Syu linux-mainline linux-mainline-headers


sudo pacman -Syu linux-lts linux-lts-headers

You switch kernels at the advanced grub menu when you reboot. Multiple kernels can be installed at the same time with Garuda.

Also, please post:

cat /etc/modprobe.d/rtl8822be.conf

You can also try revising the /etc/modprobe.d/rtl8822be.conf file. Remove any blacklist reference to rtw_pci or rtwpci and instead add:

options rtw_pci disable_aspm=Y

After revising the file again post:

cat /etc/modprobe.d/rtl8822be.conf

I hope this is not backpedaling, but have you booted into your BIOS menu to ensure secure boot is disabled? It can interfere with the performance of wifi cards, especially new ones.

@BluishHumility That would more likely be fastboot you're thinking of. If secure boot was enabled Garuda would not boot.

This is unfortunately a wifi adapter with a long history of issues.
