Wifi connection randomly cuts off and after clicking WiFi icon it just comes back

Already removed it.

error: command failed to execute correctly got this at the end

garuda-update should have fixed this:

did everything. Now I'll check for whole day and if there will be no cuts I will mark this as solution.

Thank you!

unfortunately it still happened

Maybe you could try disabling your wifi power saving like in the first part (Network Manager) of this post:

In addition to that, it won't hurt disabling MAC address randomization, with the Garuda Network Assistant or
https://wiki.archlinux.org/title/NetworkManager#Configuring_MAC_address_randomization

is there any alternative software to network manager better? I saw on some threads people talked about netctl

Network Manager is a standard, both for Garuda Dr460nized and for KDE. I really don't think the problem lies there, and I suggest not moving in that direction.
Just FYI you could give a look at the Arch Wiki here:
https://wiki.archlinux.org/title/Network_configuration#Network_managers

Okay I did everything person suggested from turning off power save mode on WiFi to adding kernel boot parameters. But still nothing it cuts off during me writing this reply.

Only part I didn't understood in his instructions was
" If you have already installed any other driver version then uninstall that driver before proceeding. Once the driver has been uninstalled, then install the rtw88-dkms-git Chaotic AUR driver with the following command:"

I didn't install any drivers manually so I didn't delete anything and also don't know how to delete that driver. Maybe that is the problem or else idk what to think.

Correct.
I'm sorry that it can't be figured out.
Let's wait for better suggestions.

Have you got a usb network dongle you could try? It sounds like this is a hardware fault on your internal network adapter as it is intermittent.

A couple of other ideas:
Disable IPv6
Try using a static IP address

Do you still have this service running? If something is triggering the service in error, that could cause this issue.

You could test by temporarily stopping the service:

sudo systemctl stop network-restart.service

Before installing Garuda i was running windows for 1 year on this computer, but never faced simillar issues. By saying hardware problem you mean that it is not compatible with the kernel or actual hardware is messed up?

I will try it and also will stop network-restart.service as suggested below.

My Connection Preference settings are

Socket read: 15seconds
Proxy connect: 10seconds
Server connect: 20seconds
Server response: 600seconds

Global Options
Mark partially uploaded files: Checked
if cancelled, automatically delete partially uploaded files smaller than: 5120bytes

FTP Options
Enable passive mode(PASV): checked
Marke partially uploaded files: checked

I haven't changed this options at all since installing Garuda so settings are default.
During garuda-update I get this error frequently:
Custom flags should be put directly in: ~/.config/code-flags.conf
idk maybe it has nothing to do with this topic, but maybe it does so I'll include it. Either way I will at least try to resolve errors which I get during updates.
last garuda-update errors which I did 10mins ago are:

error: failed retrieving file 'linux-zen-5.18.5.zen1-1-x86_64.pkg.tar.zst' from tux.rainside.sk : Operation too slow. Less than 1 bytes/sec transferred the last 10 seconds
error: command failed to execute correctly

alongside that flags error

I had both IPv4 and IPv6 set on Automatic by default.
I disabled IPv6 and left IPv4 on Automatic.

I am a newbie to linux, but I had a realtek card too and kinda had the same issue.So I am giving my input.
Can you post your
lspci -k
There you can see which all network drivers are installed and in use.

This means nothing, your router could still be part of the problem.

  • Make sure you reboot both your router and computer.
  • If power cycling your router did not improve your connectivity then a full reset of your router may be required, see link below:
    How to Reset Your Wireless Router
  • Install the newest firmware available for your router.
  • Configure and test out a static IP address via MAC address association in your router's setup utility.

Other things to try:

  • Install and test different kernels.
  • Disable MAC address randomization.
  • Test out Garuda live boot disks with different DE's, and boot disks from other distros. If your WiFi works on any other live media, report on the kernel and driver in use.
  • Have you tested your laptop on any alternate networks?

Some of these were already suggested, but you never confirmed if you'd actually implemented these suggestions. Please provide feedback on every suggestion given, and every question put to you.
