Maybe you could check the solution which worked for this one:

Edit: Sorry, I see only now that you're not a new user and it was working before.
I just quickly saw your Wifi model...
I'm afraid you'll need to wait for someone else to support you...


What may have caused this change?

Did you update recently?

Have you tried rebooting your computer and router?

Have you tried disabling MAC address randomization?

Have you tried below yet?

Select your wifi connection in Network Manager and apply these settings:

“All users may connect to this network”

“Automatically connect to this network when it is available”

“Store password for all users (not encrypted)”

Then, reboot.

If that doesn't work try below.

Paste the commands below into the terminal and execute them:

nmcli networking off
sleep 1
sudo systemctl stop NetworkManager
sleep 1
sudo ip link set wlp18s0f0u90 down
sleep 1
sudo modprobe -rv rtl88XXau
sleep 3
sudo modprobe -v rtl88XXau
sleep 1
sudo ip link set wlp18s0f0u9 mode default
sleep 1
sudo ip link set wlp18s0f0u9 up
sleep 1
sudo systemctl start NetworkManager
sleep 1
sudo nmcli networking on
sleep 1
nmcli r wifi off
sleep 1
nmcli r wifi on

Post all inputs and outputs please.

Welcome to Garuda.


I just update my app with the default app store. Again It's only app update not mejor update. after that wifi is not connecting.

If you updated only one app (?), maybe it could be worth restoring the previous snapshot and checking if that was the problem?

Not one app. I said only app not system update. I also tried to store the previous snapshot and problem not fix

This does not make sense. Maybe you should look into how Archlinux packages/system works.
Or explain in detail what you mean.

I just app update. there was no reboot needed

First rule, when you have system problems, is


If it is not fixed, then do as you are advised from @tbg and post the full terminal input/output.

I just said that, update didn't ask for any reboot. But I already reboot the system more than 15 times with various solutions.

You did not say you have rebooted.
If we cannot communicate in English, then maybe try your native language. Maybe there is some user that can help you.

Have you read that already?
Why did you not respond?
Why did you not do as @tbg asked?
Do you really want help, or just trolling?...

Dear sir, I already post the output of the shell commands

I am sure, not all.

Have you tried changing the kernel?
5.12.1-zen2-1-zen is quite new, maybe there is something wrong there...

Those are failing.

You did not answer all the questions or provide full feedback from my prior post.

You must provide proper feedback on every suggestion or we will make no progress.

Did you have your USB Wifi adapter plugged in when you ran all the commands I gave you?

Frankly the outputs make zero sense if your adapter was plugged into the computer

When I specifically ask you to provide all inputs and outputs from commands run, I do mean all. Never Cherry pick command outputs to post, always provide the complete inputs and outputs of all commands you run.

Did you have the driver @filo listed in his first post installed? Or have you installed a different realtek driver package? Or are you simply using the kernel driver for your adapter (meaning you never installed a separate Wifi driver package).

Have you tested any alternate kernels yet? I would recommend installing at least the linux-lts kernel and perhaps the linux-mainline kernel as well.

If you are using a separate Realtek driver package then I would suggest rebuilding (reinstalling) the driver package. DKMS drivers don't usually require rebuilding regularly, however occasionally they must be rebuilt.

Have you tried deleting and recreating your Wifi connection in Network Manager?

I somewhat doubt we will make much progress with this issue, as for whatever reason (language I assume) your answers are in no way sufficient to diagnose your problem.

Again I ask, have you rebooted your router? This definitely needs to be done. You may also need to reset your router back to the factory default to correct your issue.

Did your wifi work on the live boot disk when you installed Garuda?

If so I would suggest testing the live image again to see if your adapter is still working correctly. Please let me know if your adapter is functioning properly from the live environment or on another computer.

Please answer all questions and provide feedback on any and all suggestions given or there is little chance I will be able to help you. Make a full list of every suggestion or each question I've asked and provide full feedback and answers to each and every one please. Otherwise I'm simply wasting my time here and I would rather spend my time assisting users who provide proper feedback.

If possible could you please update your thread for others benefit to indicate which of my suggestions resolved your issue.

Glad I could help and that your issue is now solved.
