[SOLVED] Wireless device spontaneusly disappears

ahtson · 2023-09-23 14:18:38

Sometimes my wireless device completely disappears, it doesn't show up in "ip link". This problem has occurred after two or three days even when I temporarily switched to Debian 12. I have a hunch that this problem could be caused by the fact that I am using public wi-fi network since it only appears when I am connected to my dormitory's public wi-fi.

Here's the output of "lspci -k"

0000:00:14.3 Network controller: Intel Corporation Tiger Lake PCH CNVi WiFi (rev 11)
        Subsystem: Rivet Networks Tiger Lake PCH CNVi WiFi
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

Here's the output of "ip link set wlan0 up" and "ip link set wlp0s20f3 up"

Cannot find device "wlan0"
Cannot find device "wlp0s20f3"

Here's the full output of "dmesg | grep firmware":

P.S. Forgot to mention that "modprobe iwlwifi" doesn't help either
P.P.S Problem can temporarily be fixed when I enter UEFI before booting into system

It repeatedly fails to initiate the firmware - very early in the boot.
In case you're using iwd, https://wiki.archlinux.org/title/Iwd#Re … after_boot
Is there a paralell windows installation?
(3rd link below)

If none of the above solves the problem, please post your complete system journal for a boot where you lost the device, eg

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

for the previous (-1) one.

No, I don't have Windows on dual-boot. I don't have any other system installed on my machine except Arch.
I have edited 'iwd.service' like you advised, but I am still not sure if it's helped. Wireless interface disappears spontaneously and I can't predict when it will happen: sometimes it happens after two or three days. If it happens, I shall edit this comment and add my system journal.

Interface has disappeared again. I have restarted my machine: here's my complete systemjournal:

You're not running iwd or wpa_supplicant in that journal.
iwlwifi loads next to an

Sep 24 21:02:52 archlinux kernel:  ? intel_tc_port_init+0x253/0x260 [i915 6fb751e1b80e25872299278c99cc688be1babce3]

in i915 and the firmware messages

a timeout before NM has even really started.

1. please try the main kernel instead of the LTS one
2. try to https://wiki.archlinux.org/title/Kernel … acklisting iwlwifi and iwlmvm and manually "modprobe iwlwifi" later (do NOT use the kernel parameter shown there, as that will prevent the module from ever loading, but you can "modprobe.blacklist=iwlwifi,iwlmvm" at the kernel commandline)

I switched kernels and it disappeared again, then I have tried blacklisting it and modprobe'ing it manually, which has helped temporarily.

What do I do? Can I remove this problem completely?

seth · 2023-09-29 15:02:13

which has helped temporarily

What does that mean? The journal you posted shows that iwlwifi was loaded automatically ~1s into the boot?

Sorry, my bad. I thought, that I can revert blacklisting after manually modprobing iwlwifi

seth · 2023-09-29 17:57:12

I'm still not sure what's that suppsoed to mean, but please try to add "modprobe.blacklist=iwlwifi,iwlmvm" to the kernel parameters, make sure ("lsmod | grep iwl") that they were not loaded, then manully load them ("sudo modprobe iwlwifi", iwlmvm should get dragged along) and monitor the impact on the wifi (notably any firmware crashes - and of course whether you can use the wifi)

If this is a race condition, this can be automized to help the system over the initial boot, maybe adding i915 to the initramfs will aready do
