Stuck when disabling Wi-Fi

Support Network
1

Hey everyone,

I’ve a problem with my Wi-Fi which completely freezes the kernel when I try to disable it.
I tried to disabled it with Gnome and nmcli r wifi off.
I can enable the Wi-Fi, everything is fine, I can connect to my SSID. The problem appear when I try to disable it.

I’m on the new compiled 6.6.6-2-MANJARO kernel.
I tried the 6.5 and the 6.1 (same problem).
I’ve read (and did not find the soluce) :

I tried to understand the problem, here is what comes out in the logs:

If someone has an idea…

Thanks !

I may not understand what the issue is here, so disregard if I am way off base:

Does the laptop have a physical button to disable wifi?
How about just disconnecting via networkmanager?

3

Hello,
What kernel are you using ?
inxi tells 6.6.6-2 but your crash log tells 6.6.5-3 ?

4

Hello :slight_smile:

No, I doesn’t have a button to turn off Wi-Fi :wink:
I tried with nmcli and I just tried in “Settings” menu, same problem.

I am currently on kernel 6.6.6-2 (after read other threads) but when I extracted the logs, I was on 6.6.5-3.

You are not alone to have this problem.
Perhaps hardware related ?

https://discussion.fedoraproject.org/t/wifi-button-causes-system-crash/97910/5

6

Thanks for the thread. It actually looks like the same type of problem.
If it’s a hardware problem, I didn’t have the problem months ago…

I didn’t try to revert the kernel to 5.x version, but, even if it’s work, I don’t want to stay on it :frowning:

7

I have not said it is a hardware failure, but that it is hardware related.
If you read the Fedora discussion you discover that the hardware is exactly the same as yours. A special hardware configuration can trigger a bug. The kernel code is full of specials “quirks” to handle that sort of problem.

8

Oh, I didn’t see it earlier ! Indeed, same “iwlwifi” drivers, maybe I should try to recompile it. pfff -_-

9

I tried on Debian 12 with the 6.1 stable kernel (nor backports) and I’ve the problem. Soooo weird.
Maybe I will find something in bios.

EDIT : OK, I tried a factory reset of the BIOS, the problem is still here…
It’s tiring me out, I’m going to try to change the Wi-Fi card, hoping to recover something other than Intel.

10

The latest available 6.1.x and 6.6.x kernels (in the last few days) have addressed recent common WiFi issues. You might try updating to those respective kernels to see if your issue is also resolved.

Report back if they didn’t help. Cheers.

11

Yeap. I said in my first message that I was on the new compiled 6.6.6-2-MANJARO kernel :slight_smile:
And today, on the 6.6.7. Problem still there :frowning:

12

Yes. My intention was to highlight 6.6.7 was available now. Perhaps you could ask a new question: “Which WiFi card should I buy?”, or similar. I don’t use WiFi, so am not much help in that regard. Good luck.

13

I understand your opinion but, since it’s a laptop, it’s rather difficult to choose which Wi-Fi card to use/buy :D, especially since it’s my work laptop :wink:

14

Ah, well, your comment lead me astray: :wink:

However, there are external options (USB) you might consider; albeit not the ideal solution. Good luck.

15

Since the card itself is supported by iwlwifi - one is left to think of a flaky card - perhaps due to overheat - electronics tend to be sensitive to that.

Have you cleaned you system inside for dust?

USB wireless dongles comes at very low prices - since it is a work laptop - if it were me I would have talked to the IT dept. of my employer to get a replacement.

You could use rfkill on the command line to shutdown the device - see if this change the behavior.

man rfkill
16

I have the same problem in arch linux.
the kernel freezes whenever i do:

  1. nmcli r wifi off
  2. turn the wifi off from gnome gui

also rfkill stops working after trying to turn the wifi off.

i have tested in 6.6.5.16.realtime1-1-rt and 6.1.69.lts-1

my laptop is dell precision 5540 with “Intel Corporation Wireless-AC 9260” network controller

17

Already checked. The laptop is clean. Besides, the plastic is cheap, I cracked it when I opened it… :man_facepalming:

Same problem when using rfkill block… :smiling_face_with_tear:

Moreover, I note that via rfkill, the card is referenced “dell-wifi”.
I would try the support but I’m afraid of wasting time for nothing…

18

I have the same problem so as 2 of my colleagues here at work using DELL Latitude 55xx laptops.

It started to happen after kernel 6+ updates on Fedora. I switched to Garuda Linux which is based on Arch and it still happens, and someone above said he/she had the same problem using Debian.

This is not a hardware issue, this is ‘iwlwifi’ related and so kernel related.

Still happening as of today with kernel v6.6.10.

I suggest you upgrade your kernel to the latest 6.6.x iteration.

There was an apparent regression affecting 6.5/6.6 as well as the 6.1 LTS that caused WiFi issues for a number of users. The latest iterations have brought some resolution.

Naturally, if your issue lies elsewhere, this won’t help much.

Cheers.

Thank you for your suggestion @soundofthunder

In the meantime, I’ve checked 6.7.0 and while the freezing issue is gone on RF_KILL, iwlwifi module still records a lot of garbage in the system log. Just adding this for the record: https://pastebin.com/raw/gpPmVCGC

So based on the few tests I’ve just made, 6.7.0 seems to fix it.
