[HACK-AROUND] Wifi randomly stops working.

The wifi of my old Lenovo Thinkpad X220 randomly stops working since the last update. It also won't come back after the device awakes from sleep. If I try to reboot the laptop, the problem persists but it disappears if I shutdown the laptop and boot it some time later.

Here is the relevant output of `lspci -vvv`

03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
	Subsystem: Intel Corporation Centrino Advanced-N 6205 (802.11a/b/g/n)
	!!! Unknown header type 7f
	Interrupt: pin ? routed to IRQ 29
	Region 0: Memory at f2400000 (64-bit, non-prefetchable) [size=8K]
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

and the version of linux and llinux-firmware:

    - linux-firmware : 20240115.9b6d0b08-1
    - linux  : 6.7.arch3-1

And also the output of  dmesg

Re: [HACK-AROUND] Wifi randomly stops working.

Does the problem also happen in the live environment? The card might be dying.

And please use code tags when posting terminal output, it greatly aids readability. Edit your OP to incorporate them. Thanks.

Are you infected with Wetiko?

I'm not sure if I understand your question correctly. As I said earlier, the wifi keeps crashing randomly when I'm using my laptop. I've tried downgrading the linux and linux-firmware packages, and that seemed to be working fine for a while, but I had to bring them back to the latest version because the laptop simply won't wake up from sleep.

Re: [HACK-AROUND] Wifi randomly stops working.

HoaS is suggesting that this is a HW issue, hence whether this is a problem w/ other SW stacks like the install iso or a live distro like grml/knoppix/…
That being said: https://www.google.com/search?client=qu … hlinux.org

https://bbs.archlinux.org/viewtopic.php … 1#p2120681 and if that's not it, please post your complete system journal for a boot showing the crash in context: 

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

Edit: https://bbs.archlinux.org/viewtopic.php?id=290682 has this on a system where  the RJ45 acts as an implicit rfkill

I didn't try to reproduce the issue in a live environment, and I do not have any bootable USB close by. Do you know some other way I could make sure this is just my hardware deteriorating ?

I tried to set pcie_aspm=off to no avail. The issue persists.

I did not notice any correlation of the issue with the use of a wired connection.

You're connecting 6:40:33, probably still have a connection at 07:20:41 and briefly afterwards lose the signal, leading to a firmware reset ~3 minutes later

Problem #1 is

Jan 21 06:41:33 emma iwd[352]: Unexpected connection related event -- is another supplicant running?

=> Disable iwd.

Re: [HACK-AROUND] Wifi randomly stops working.

Tried disabling 'iwd' with

 sudo systemctl disable iwd

And then I disabled the wifi, and then tried to bring it back again, unsuccesfully. The problem persists.

Re: [HACK-AROUND] Wifi randomly stops working.

iwd still shows up in that journal and it certainly has trashed iwlwifi.
Also "disable" doesn't do anything immediately. Reboot and report on the new status.

Rebooted. And I checked the status of iwd:

$ systemctl status iwd
○ iwd.service - Wireless service
     Loaded: loaded (/usr/lib/systemd/system/iwd.service; disabled; preset: disabled)
     Active: inactive (dead)
       Docs: man:iwd(8)
             man:iwd.config(5)
             man:iwd.network(5)
             man:iwd.ap(5)

Grepped through the journal, and found not mention of it either.

Result:
Problem seemed to be resolved for a while. Could power the wifi up/down, get it back on when waking from sleep, etc. Waited for a while, and tried again: problem returned.

It looks like the NIC got rfkill'd and unkill'd within  seconds - did you purposefully stress-test it to cause this?
Did you push the rfkill switch/button at all? (Some increasing amount of devices use the rj45 plug as implicit rfkill)
Is there a parallel windows installation?

Re: [HACK-AROUND] Wifi randomly stops working.

And I tried a reboot again, but this time, the boot halted with the message

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card (FFFF/FFFF).

System is halted

I had to shut it down by a long press on the power button.
I run

journalctl -k -b -1

to retrieve the logs for the previous boot, and I posted them at http://0x0.st/H0CG.txt

Yeah. I use the GNOME settings app to turn the wifi off then on. I did not use the rfkill button. I do not use the rj45 plug at all so I don't think this could be an implicit rfkill from it. There is no parallel Windows installation, Archlinux is the only OS installed on the laptop.

And also, in an attempt to bring the device back up after the error without having to reboot,  I've been trying to use sysfs to remove the PCI device, and rescan: the remove operation works, but the rescan has no effect; the device doesn't come back, nothing shows up in the log. A clue ?

Re: [HACK-AROUND] Wifi randomly stops working.

Is it a necessary/reliable trigger for the problem? (Notably the high frequency)
The subsequent reboot problem *might* have been because the FW left the HW in a bad state, notably if it's not recurring.

Re: [HACK-AROUND] Wifi randomly stops working.

I'm a bit out of ideas about where to look. With ASPM off, iwd disabled, the problem seems to occur not under the conditions I mentioned in my first post (wake up, turning wifi off/on), but just randomly after some time (~ 1/2 hour, I'm guessing), whether or not I use some kind of rfkill, and less if I stress test it. I don't have a clue about what is causing what and I'm starting to think that HoaS might be right about the card dying. @seth do you know if there's some way I could bring the device back up after it crashes, without going through a reboot ?

Re: [HACK-AROUND] Wifi randomly stops working.

Your best shot is likely to remove the device, unload the module and rescan the bus.

lspci -tvnn

Re: [HACK-AROUND] Wifi randomly stops working.

OK. Tried that and put it into a function in my .zshrc

wifi_restart () {
	echo 1 | sudo tee /sys/bus/pci/devices/0000:03:00.0/remove > /dev/null
	sudo modprobe -r iwldvm iwlwifi > /dev/null
	echo 1 | sudo tee /sys/bus/pci/rescan > /dev/null
}

Result: it works every time I tried it to bring the wifi back up when it crashes.
@seth do you know I could somehow automatically configure the script to run every time the crash occurs ? I'd also like to collect some data on how often the crash happens for a few weeks so I need a way to automatically detect it in the background, handle it ,and log it to some file ...

Re: [HACK-AROUND] Wifi randomly stops working.

And also, I'm new to the forum. As this is a partial fix, shall I add [SOLVED] to the title ?

Re: [HACK-AROUND] Wifi randomly stops working.

You would likely have to have to use a https://wiki.archlinux.org/title/Networ … dispatcher to hook onto the symptom (down or connectivity-change), check the tail of dmesg (or rather the journal, so you can compare timestamps) for the crash pattern (eg. if __iwl_trans_pcie_grab_nic_access is consistent) and then reload the device and log the event.

"[HACK-A-ROUND] "…

Edit: on a formal note it's better to not personally address questions, "@seth" does nothing special (you get mails for every subscribed topic anyway) and you're drastically limiting your resources.
If I was empathic, I'd also concern that it's a bit dismissive towards everyone else but since I'm mostly an asshole, I just don't want them to feel like they could lazily ignore the question tongue

Re: [HACK-AROUND] Wifi randomly stops working.

Thanks.
But I think I may have declared victory too soon ... The fix worked fine, survived all the stress tests and then after some time, the interface will come back up, just to crash back immediately.
I uploaded the full log at http://0x0.st/HG-P.txt and it may be a bit redundant because I tried the rescan again and again ...
I've gone through it and there's lots of new stuff I don't get, especially this line

Jan 22 05:36:13 emma kernel: ieee80211 phy1: Selected rate control algorithm 'iwl-agn-rs'

I run

lsmod | grep "ieee80211"

and it comes back empty.
I dot not understand ... I thought it was some kernel module, but found it nowhere.

Re: [HACK-AROUND] Wifi randomly stops working.

https://en.wikipedia.org/wiki/IEEE_802.11 - the module is mac80211
Try to limit the rescan to the relevant bus (if you can't figure which it is, "lspci -tvnn" will tell)

Re: [HACK-AROUND] Wifi randomly stops working.

Is this what you mean ?

echo 1 | sudo tee /sys/bus/pci/0000:03:00.0/rescan

Tried. Result:no effect.
And because the file will disappear after I removed the device, I can't run a specific scan on the device after that.

Re: [HACK-AROUND] Wifi randomly stops working.

No, that's the device. Please post the lspci output.
