[SOLVED] No results in iwctl for station wlan0 on a laptop

Fractal-Tess · 2023-11-14 18:05:43

Hey there,

I'm unable to get any results for network SSID when scanning for them in iwctl using my wlan0 (laptop-s built-in network adapter).
I checked on Windows (dual booting) to confirm whether or not the network card is dead or not, but it works like normal.
I'm not sure what could cause this, since it was working perfectly fine yesterday. One thing that comes to mind that could have bricked it, is that I entered an installed media to resize my boot drive (allocate more of the SSD towards Windows (grow windows, shrink Linux)).

I'm currently using an external USB antenna and I'm connecting to my router via station wlan1, but I would like to know how I can attempt to debug and fix wlan0 (the laptop's internal network card).

Please use [code][/code] tags, not "quote" tags. Edit your post in this regard.

I checked on Windows (dual booting)

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Here is journalctl -u iwd
...skipping...

If it's not the dal-boot issue, please post your complete system journal for a boot after trying to use the NIC:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Fractal-Tess · 2023-11-14 21:15:22

I went ahead and disabled fast start and hibernation with the following command powercfg /H off and proceeded to reboot 2 times - then i also rebooted my Linux 2 times.
After that, I booted into Linux, and started up iwctl to get the same result - station wlan0 get-networks returns an empty list even after issuing a scan.

Here is the sudo journalctl -b - https://0x0.st/HvMP.txt

I am not exactly sure what you mean by that.

Would you like me to use some other kernel version? And if so, how do i go about doing that?

https://archlinux.org/packages/core/x86_64/linux-lts/
You'll also need https://archlinux.org/packages/extra/x86_64/nvidia-lts/
And depending on your bootloader re-configure that (eg. w/ grub-mkconfig)

Im unable to install the linux-lts kernel. Paru fails with the following output:

edit:
I deleted some stuff from /boot - mainly some fallbacks and .tmp files to make room for linux-lts.
After that i did sudo update-grub and rebooted into linux-lts - uname -r - 6.1.62-1-lts.
Using that, i went ahead and tried to use the NIC once again, but again it shows no networks in iwctl.

Here is journal -b - https://0x0.st/HvM_.txt

That's the limited space on your boot partition.

You can either replace the kernel (remove linux and nvidia, install linux-lts and nvidia-lts) or try to safe space by possibly removing the nvidia modules from the initramfs (the firmware files blow them up tremendously) or remove the fallback images and also edit the /etc/mkinitcpio.d/linux*.preset files to prevent their generation.

Make sure to have the install iso or some live distro at hand - it's not really complicated or systematically risky to change the kernel, but if you manage to screw this up, you'll have to fix the system offline.

Check the edit above - I did it slightly before you posted this message.
Also now that I've done a full system update by running paru - equivalent to pacman -Syu and also updating grub with sudo update-grub, i've lost the ability to use my external USB antenna to connect to the router.
It used to show up before as wlan1, but it is now no longer there. I'm now using usb tethering from my phone to write this message.

edit:
I just found out that if I used the latest kernel 6.6.1-arch1-1, the system is able to recognize the USB antenna and it shows as wlan1 in iwctl.

Same condition.

On either kernel?
You're probably using one of https://aur.archlinux.org/packages?O=0&K=rtl8812au for that and certainly lack linux-lts-headers for the DKMS.

Edit:
https://bugzilla.kernel.org/show_bug.cgi?id=215496#c22 seems to have it down to some PM, you could try to add "pcie_aspm=off" to globally disable that and see whether the NIC behaves afterwards. If yes, you can isolate the NIC

Should i be able to run

 modinfo rtw_8822ce

, because it is throwing me this error

modinfo: ERROR: Module rtw_8822ce not found.

Here is lsmod | rg rtw -

Another thing is that after I installed rtl8812au-dkms-git which I blindly assumed is the correct one purely by it's popularity compared to the rest ( please correct me if it's not ), and also linux-its-headers, the USB antenna is still not showing up like it does for the latest kernel.

Also, where exactly should "pcie_aspm=off" to be added to?

Edit:
I think I messed up with playing around with different settings, and after adding this pcie flag to grub cmdline, my xorg no longer wants to start.

Ah, forgot that the module misrepresents its name.

If you first installed rtl8812au-dkms-git (you need one such package anyway for the dongle?) and then the headers you'll still need to build the module, https://wiki.archlinux.org/title/Dynami … le_Support
But you can ignore that for now - both kernels have the same problem.

Also, where exactly should "pcie_aspm=off" to be added to?

https://wiki.archlinux.org/title/Kernel_parameters

Edit: "pcie_aspm=off" isn't applied in those logs.
Get rid of xf86-video-ati.

Most likely move amdgpu back into the initramfs.

I did add it there, and doing cat on /proc/cmdline shows that the flag is there, however, there is no change in the behaviour of wlan0.

Also like I mentioned before, xorg is now not in a working condition. Any clue why that might be the case from the logs?

Most likely move amdgpu back into the initramfs.
The pattern also showed up in https://bbs.archlinux.org/viewtopic.php … 8#p2043368

Yep, i was just about to do that one, but i did i a Windows boot and reboot, into a cold shutoff. Now the system automagically works? I'm failing to comprehend what just happened, but I'm so happy I no longer have to fight with configs and black screens.
Xorg works, wlan0 works... Awesome!

I think the cold shutoff did the trick.
What are your thoughts?

Thank you so much for the help and guidance @seth.

What are your thoughts?

The only way this works is through residuals of the fast-start condition.
(The hibernating windows breaking your wifi is extremely common, so principally that's no surprise - but I might have to raise the voodoo to three reboots now…)
