If you haven’t already tried it, then test disabling MAC address randomization.
Another thing you can try is downgrading your firmware if your wifi was working on Garuda or another Arch based distro in the past. As this is a new install @mak-bacc, you will have no older firmware versions stored in your package cache to test downgrading with. However, you can still test older firmware versions by following the method below.
How to downgrade the linux-firmware from the Arch Archive:
Often newly released driver or firmware versions can cause regressions that create unforeseen new problems.
If your Wifi was working correctly in the past, you may want to try downgrading your firmware to an older working version.
You can downgrade to an older linux-firmware version directly from the Arch Linux archive source online.
Older linux-firmware packages can be found at:
You can test any olderlinux-firmware version from the above link to see if an older version is free of the current bug you are experiencing.
For instance, if you know your wifi was working correctly in the summer of 2025, you might want to test the 27-Jun-2025 release:
linux-firmware-20250627-1-any.pkg.tar.zst
To install and test the linux-firmware-20250627-1-any.pkg.tar.zst package , you can do so directly from the Arch Linux archive using pacman.
Example:
sudo pacman -U https://archive.archlinux.org/packages/l/linux-firmware/linux-firmware-20250627-1-any.pkg.tar.zst
After you have finished installing any alternate linux-firmware package, be sure to reboot and test for any improvement.
If you find no improvement by testing older firmware versions, then simply reinstall the current linux-firmware package with:
sudo pacman -S linux-firmware
