My wifi driver/connection option are suddenly gone? Cannot use WiFi at all anymore

[MeKle]

Hello there, I need help to get my WiFi working again.

Up until yesterday WiFi etc. worked like a charm for more than a year.
Yesterday when I tried to wake my laptop from sleep mode Linux just did not woke up (fans and leds lit up, display kept being dark), so I shut it down the hard way after a while.
After the next boot: wifi does not work anymore. While I can see my previous saved wifi connections, I cannot connect to any of those or find new ones, the taskbar does not show any options etc. It is as if there was no WiFi card installed but device manager etc. still list it.

• Bluetooth and network connections via LAN or USB-hotspot still work
• I did not run a update/upgrade the sessoin before mentioned shutdown
• I did run garuda-update afterwards in hopes it might fix something, alas it did not
• I did a full reboot afterwards (several actually)
• This is not a dual-boot machine, using Garuda Linux only
• In the Garuda Network Assistant I can “turn on/off” wifi, but nothing happens when doing so
• … also there are no “associated Linux drivers” listed, although the wifi hardware still shows up in the upper part
• I am a Linux user, not a pro, please be patient

I boiled down the garuda-inxi, if you need the rest just tell me.

Please help me out, thank you!

Hello MeKle,

may some fault in loading the driver.
driver:N/A should be iwlwifi.(i have the same AX200 )

@MeKle

Device-2: Intel Wi-Fi 6 AX200 driver: N/A 

you can try those steps.

1. Ensure the linux-firmware package is installed. This package includes the necessary firmware for the iwlwifi driver. You can install it using the following command:

sudo pacman -S linux-firmware

2. Verify that the iwlwifi driver is loaded. You can do this by checking the output of the dmesg command or by looking at the kernel log:

sudo dmesg | grep iwlwifi

If the driver is not loaded, you can manually load it using:
before turn off wifi and after load turn on again.

sudo modprobe iwlwifi

my AX200 output below:

If the above does not help, I’d suggest a cycle power of your laptop and if necessary possibly also a BIOS reset to factory default (take note of your current settings), as suggested here (focus only on the relevant part, of course, and remember that with a laptop you should possibly also remove the battery:

Bluetooth not working on my new install

I noticed this as well, usually testing other kernels is the most likely thing that will fix that. Test the linux , linux-mainline , and linux-hardened kernels as well. You could also try replacing the Bluetooth management utility bluez with blueman. To install the blueman package, issue the following command: sudo pacman -S blueman If none of the above suggestions helped then try the procedure below: A network adapter not being detected properly can sometimes be corrected by power cyc…

All the above suggestions are good, give them a try.

IMO, if your last system update included either the kernel or the linux-firmware packages, then those updates are likely the cause of your problem.

My first suggestion would be to test out at least three alternate kernels, such as:

linux-lts
linux-hardened
linux

If the linux-firmware package was updated just before your WiFi breakage, then I would suggest downgrading the linux-firmware package.

Thank you so much, this helped like a charm!

I have no idea why, since I did not update anything for several days (and reboots) before the issue started, but for some reason the aforementioned linux-firmware package was apparently not installed (anymore?).

So I got that, modprobe and another reboot → WiFi works again.
