Realtek RTL8822BE - wifi unable to connect

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.

Edit:

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

or:

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

or:

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.

The other thing that comes to mind is regarding this:

It is possible your phone is broadcasting at an 802.11 channel that your router is not. Depending on your router, you may be able to log in and configure different channels to find the one that your wifi card is able to pick up.

Here is what mine looks like:

I changed the 802.11 mode on our router to b/g/n mode because we had this old Roku device that needed the b channel (or n channel, I forget, doesn't matter!). I would try out a few different channels and see if you can find one that works.

As far as the frequency goes, your phone is probably broadcasting at 2.4 GHz (unless you configured it otherwise), but again it might be worth playing around and seeing if you can set it to a frequency that your laptop will pick up.

A post was split to a new topic: Hijack from another distro

I've switched into linux lts and updated the system, wrote that line in /etc/modprobe.d/rtl8822be.conf , rebooted but nothing changed: still facing the same problem.
Btw, I don't think that the problem is related to my router as the wifi was working when I just installed Garuda Linux.

Running the line : cat /etc/modprobe/.d/rtl8822be.conf justs displays : options rtw_pci disable_aspm=Y


@pro, I apologize for locking your thread and not reopening it for days. It was the only way to stop a very persistent user from hijacking your thread continually with unrelated posts.


If you still have the rtw88-dkms-git driver installed (reinstall it if you don't), try blacklisting the rtw88_8822be module.

Create or modify the following file:

/etc/modprobe.d/rtl8822be.conf

Add only the following line to the conf file, (delete any other entries):

blacklist rtw88_8822be

Then reboot.


If the new blacklist doesn't help, then try below:


Disable IPv6 and set your WiFi to performance via kernel boot parameters:

If you are unfamiliar with how to add a kernel boot parameter it can be done easily by using the following command:

sudo cp /etc/default/grub /etc/default/grub.bak && sudo sed '/^GRUB_CMDLINE_LINUX_DEFAULT=/s/"$/ pcie_aspm.policy=performance ipv6.disable=1"/g' -i /etc/default/grub && sudo update-grub 

Press ENTER again if the grub update process does not start scrolling onscreen.

The process wil take a little while to complete, and this is perfectly normal.

Once the grub update process is complete, reboot.

If the change does not improve your connectivity you can restore the file to its original state with:

sudo cp /etc/default/grub.bak /etc/default/grub

After restoring the grub file, again run:

sudo update-grub 

Then reboot again.


If none of above helps, then please post:

systemctl status iwd.service
systemctl status wpa_supplicant.service
systemctl status NetworkManager.service
pacman -Q rtw88-dkms-git
grep -r "blacklist\|install\|options"  /etc/modprobe.d/ /etc/modules-load.d/ /usr/lib/modprobe.d/

I hope that helps get things working @pro.

Try using the iwd utility to connect. For example,

  • Find your device name
iwctl device list
  • Search available WiFi providers, using the device found from previous command (example wlan0)
iwctl station wlan0 scan

Read manual, how-to usage and test. Post feedback.

Sadly, there have been so many changes at this point that it may be impossible to figure out what needs to be done to effect a fix (if that is even possible with your adapter).

I rarely ever tell people this, but it may be that reinstalling is the only way to methodically work through what needs to be done. Immediately after reinstalling create a snapshot of your system.

Was your wifi working on the live disk before you installed?

Was the wifi working immediately after install, before you rebooted?

If the answer is yes to either of those questions, you may be better to perform an offline install without an internet connection.

That way you could take a system snapshot immediately after install and have a known good working setup to roll your system back to.

We would then need to meticulously work through steps one at a time to pinpoint the changes that will result in giving you a working setup (after performing an update).

If you perform an offline install, do not make any changes without my instructing you specifically to do so. Simply take a system snapshot immediately after installation and then wait for me to tell you what to do.

Sorry, but this seems the most straight forward way of finding the cause, and any possible fix for your issues.


If you haven't given up on your issue completely I have an Idea on how to sort through all the different modules and the different driver options that need to be tested. My thought is to blacklist every rtl8822be related module and then test the different modules and options via modprobing. Creating the blacklist file required for this will also disable your bluetooth. Bluetooth can often interfere with proper wifi operation on some wifi/bluetooth combo chips such as yours, so we need to test disabling it. If you are using bluetooth devices such as a wireless mouse or keyboard you will need to substitute a non-bluethooth device during this test.


Create the following file:

/etc/modprobe.d/rtl8822be-blacklist.conf

Add the following lines to the rtl8822be-blacklist.conf file:

blacklist btrtl
blacklist btusb
blacklist 8822b
blacklist 8822be
blacklist r8822b
blacklist r8822be
blacklist rtw88
blacklist rtw88_8822b
blacklist rtw88_8822be
blacklist rtw88_pci
blacklist rtw88_core
blacklist rtwpci
blacklist rtw_pci

This file will blacklist all the rtl8822be driver modules including Bluetooth, (preventing all from auto-starting).

Save the blacklist file, then run:

sudo depmod -a && sudo mkinitcpio -P

Then power down (not reboot).


After restarting, install/reinstall the rtw88-dkms-git driver from the Chaotic AUR:

sudo  pacman -Syu rtw88-dkms-git

After the installation is complete, again run:

sudo depmod -a && sudo mkinitcpio -P

Then power off completely, remove the power plug and battery, (if possible). Wait for a minute or so, reconnect power, then boot into Garuda.


After restarting, issue the following command:

sudo modprobe rtw_pci disable_aspm=1

Check your wifi connectivity, and if no better then issue the following command:

sudo modprobe -r rtw_pci ; sleep 3; sudo modprobe rtw_pci disable_aspm=y

If your connectivity is still no better, then reboot.


After restarting, issue the following command:

sudo modprobe rtw88_8822be

Check your wifi connectivity, and if no better, then reboot again.


After restarting, issue the following command:

sudo modprobe rtw88_8822be disable_aspm=1

Check your wifi connectivity, and if no better, then reboot again.


After restarting, issue the following command:

sudo modprobe rtw88_pci 

Check your wifi connectivity, and if no better, then reboot again.


After restarting, issue the following command:

sudo modprobe rtw88_pci disable_aspm=1

Check your wifi connectivity, and if no better, then reboot again.


After restarting, issue the following command:

sudo modprobe rtw88_core disable_lps=y; sudo modprobe rtw88_pci disable_aspm=y disable_msi=y

Then check your wifi connectivity.


Hopefully, modprobing one of the driver/options will successfully initiate your wifi. Once this is determined, we can then figure out how best to configure your system for this to work automatically, (without requiring a manual modprobe). Please report on all results by providing the terminal input and output of all modprobe commands run.


Hopefully one of the above modprobe commands now has your wifi working correctly.

If so, and you require Bluetooth to be working run this command:

sudo modprobe btrtl; sudo systemctl restart bluetooth: sudo bluetoothctl power on

If your bluetooth and wifii are still working correctly after running that command, then you should check if bluetooth can be re-enabled permanently.

To check if bluetooth can be permanently enabled, alter the blacklist file contents to this:

#blacklist btrtl
#blacklist btusb
blacklist 8822b
blacklist 8822be
blacklist r8822b
blacklist r8822be
blacklist rtw88
blacklist rtw88_8822b
blacklist rtw88_8822be
blacklist rtw88_pci
blacklist rtw88_core
blacklist rtwpci
blacklist rtw_pci


Comment out the blacklisting of the two bluetooth modules with hash tags, (as above). You must restart the computer for these changes to take effect. If your wifi and bluetooth are still working after startup, then the bluetooth entries can be removed from the blacklist permanently. If your wifi and bluetooth are not working after removing the bluetooth entries from the blacklist, then you will need to blacklist them again. If your bluetooth can be restarted manually, then you will need to run those commands after each startup. You could alternatively create a service to start your bluetooth automatically for you.

You can delete the /etc/modprobe.d/rtl8822be-blacklist.conf file entirely if does not improve your wifi.

Reboot after making any alterations to configuration files in /etc/modprobe.d.

I worked through the rtl8822be driver issue with another user recently. The process for getting the driver working correctly is located here:

Hi there @pro.

What up bro?

I've typed up a thousand word essay since you last responded on your own help request 12 days ago. I see you were online a few days ago, yet you didn't have the common courtesy to even acknowledge the attempts from several admins to help you with your issue in going on 2 weeks.

Has your issue been resolved yet?

If not, see the link I posted for a likely fix for your adapter. I put in a lot of effort refining the steps I first posted here to solve the riddle of what was required to get the Rtl8822be adapter working. The user on that thread stuck with it until the end to find a solution (unlike yourself).

From all appearances you made a cry for help here, then simply abandoned your thread without so much as an acknowledgement or thank you to those who attempted to help you.

Very poor form my friend.

If your issue is now resolved, please mark the thread solved. I don't like to leave threads dangling in the Network Support category as I always try to see them wrapped up in some way that will help other users with the same issue.
