[User created issue] Wifi No Connection Available

I am sorry. I'm new to Linux. I have a problem not being able to connect to any wifi. not even wifi detected.

I can now connect via LAN, and USB Tethering, and I can also create a Hotspot. Previously I always used LAN, because I moved house, so there was only Wifi. I realized that wifi is not detected after I managed to create a hotspot using GitHub - lakinduakash/linux-wifi-hotspot: Feature-rich wifi hotspot creator for Linux which provides both GUI and command-line interface. It is also able to create a hotspot using the same wifi card which is connected to an AP already ( Similar to Windows 10). .

When I run

sudo iwlist wlo1 scan

the result is

wlo1      Interface doesn't support scanning : Network is down

I try run

sudo ifconfig wlo1 up

but still not working

this is the result of ip addr

Hi there, welcome to the forum!
I think you could try changing your WiFi driver as explained in this post.


Was it working before then?

If so, revert the changes and make sure it's still working before changing anything else, then you can decide whether the linux-wifi-hotspot software is reliable enough to spend the time trying to make it work (if it even works with your hardware).

I have already tried this, but still not working.

yes, it worked before. I tried to restore using BTRFS Assistant, but the snapper can only recover after 29/06/22. as far as I remember the wifi was not working before that date. and I've also tried recovering to 29/06/22 and it still doesn't work.

Have you tested the linux-lts kernel yet?

If not, please do so.

i just tried to change the kernel. but still not working

Are you sure you booted into the LTS kernel?

╭─[email protected] in ~
╰─λ mhwd-kernel -li
Currently running: 5.15.52-1-lts (linux-lts)
The following kernels are installed in your system:
local/linux-lts 5.15.52-1
local/linux-zen 5.18.9.zen1-1

now, I can use wifi.

sudo pacman -S linux-firmware

and previously in /etc/NetworkManager/NetworkManager.conf
there is


after i removed it and restarted networkmanager. I can connect to wifi again

That would appear to be reverting changes you have made to your system rather than fixes to what Garuda provided... But, it's good you found the reason things broke for you.
