 Posted: Mon Mar 06, 2023 11:00 am Post subject: Wifi Interface goes down after couple hours of use |
 |
|
Hello,
My wifi interface goes down after using the pc for couple hours and sometimes after suspending to ram. When it goes down I can't set it up using ip link (RTNETLINK answers: Connection timed out). I also noticed that ip link and ifconfig commands gets stuck for couple seconds before running when this happens. I am using NetworkManager if that helps, restarting nm didn't help. Everything works after a reboot for couple hours.
Wifi card: Intel AX 210 (I emerged sys-kernel/linux-firmware and confirmed that I have the driver on the intel's page under /lib/firmware/)
Kernel: 6.1.2 (genkernel)
Dmesg output: https://paste.bingner.com/paste/3qptp
lspci -v output: https://paste.bingner.com/paste/fw278
Can you help me figure out the problem and solve it?
Thanks. |

Hello,
when this problem happen, instead of rebooting you can stop NetworkManager and unload the iwlwifi module and load it again using the modprobe command. Than it should work again. Many network devices do not support hivernation. I don't know exactly why your Intel wifi stop to work but be sure that the power management is of on the card. These are my parameters for iwlwifi in /etc/modprobe.d/modprobe.conf:
options iwlwifi 11n_disable=1 bt_coex_active=1 disable_11ac=0 disable_11ax=1 enable_ini=0 fw_restart=0 led_mode=3 power_level=1 power_save=0 swcrypto=0 uapsd_disable=1
Playing with the iwlwifi parameters can help. The value of the parameters depend on which band you use to connect, 2.4ghz, 5ghz, 6ghz. Me is 5ghz channel 165. Look at
modinfo -p iwlwifi
You can try dhcpcd as a replacement for NetworkManager. It work well with wifi.

Thanks Logicien, in dmesg messages a newer version than intel's recommendation was being used and I deleted all fırmware except the recommended one. It didn't help, also I tried to unload the iwlwifi and iwlmvm and after loading them again I saw that my wifi interface was gone. It's not even showing on ip link command as "DOWN" so I had to reboot again.
I'll try to play with iwlwifi parameters as you recommended, if it won't work I'll try to downgrade my kernel.
Edit: I also noticed that the issue happens more frequently if I'm downloading stuff, noticed it when I was trying to download a game from steam |

obfusc8,
When the WiFi goes down, are there any error messages in dmesg?
What does show?
What is the output of
What is the content of /etc/resolv.conf

Hello NeddySeagoon,
I have upgraded to kernel 6.2.0 to see if issue persist and it does.
Here is the updated dmesg: https://paste.bingner.com/paste/a9tnr the error message(s) starts right after the line starting with [ 170.769942]

Do you have an older kernel that works?
Can you try and older kernel?

NeddySeagoon,
I was using 6.1.2 but I had the same problem. I don't want to downgrade to 5.x since my GPU is supported on kernel 6.x+. Is there nothing else I can do? |

try to enable IOMMU in your kernel configuration. Do you have then still problems ? |

obfusc8,
How adventurous are you?
The current tip of Linus's tree is 6.3-rc1. sys-kernel/git-sources should install that.
-rc1 means that its the first cut of 6.3.0 available for testing. Don't just try it. It will be buggy, that's why its a release candidate, the first one too.
Read the change log for iwlwifi. If there are no bug fixes, its probably not worth testing.
If you are feelling more adventurous still, patches appear on that list.
You search engine may find Red Hat bug 1429135.
It says to turn off in the kernel.
Note that its hidden behind | Code: | | depends on IWLMVM && IWLWIFI_PCIE && PM && EXPERT |

NeddySeagoon,
I don't see
in my config, can it be an option for older kernels? On the bugzilla page, it seems they are using kernel 4.9.12.
Thank you for for your help, I really appreciate it. I'll probably roll back to 6.1.2 for now and order a cat cable long enough to reach my PC. Hopefully it'll be fixed in an upcoming release.
Also, should I create an issue on Gentoo's bugzilla page for this? |

obfusc8,
Its gone. All that is left now, in my 6.2.0 is.
| Code: | │ │ < > Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi)│ │
│ │ - - Intel Wireless WiFi DVM Firmware support │ │
│ │ - - Intel Wireless WiFi MVM Firmware support │ │
│ │ *** WARNING: iwlwifi is useless without IWLDVM or IWLMVM *** │ │
│ │ Debugging Options ---- │ │ |
Something else to try.
will give you a list of module parameters that can be set at module load time.
Sometimes they can be changed is /proc or /sys too.
If the power saving is on, try | Code: | modprobe -r iwlwifi
modprobe iwlwifi force_cam=1 |
to turn it off.
If that or other module parameters help, they can be applied at startup automatically.
-- edit --
If you ping your router continuously in another console window, to the wifi alive, does the problem still happen?

NeddySeagoon,
I am unable to reproduce the issue at the moment. It seems it's only happening when I'm using traffic 'heavily'. As I am not downloading anything right now it's working without a problem. I'll try turning off power saving tomorrow and download some random stuff to test.
Thanks. |

I forgot to says that I have this parameter too for the module iwlmvm in /etc/modprobe.d/modprobe.conf
| Code: | | options iwlmvm power_scheme=1 |
If I remember well disable the bluetooth coexistence in iwlwifi
| Code: | | options iwlwifi bt_coex_active=0 |
make the module crash or unusable. All my parameters of iwlwifi have to function to not manage the power for economy. My parameters disable too all the bands that I dont use to focus only on the 5ghz band as a client. To say the true the best wifi card I have on PCIe is a Realtek. I do not find Intel wifi cards so good on Linux. I prefer Atheros or Ralink. I don't see any problem with Linux using those cards.
I can suggest to use an other Linux distribution to check if the Intel wifi card work well and if yes configure your Linux kernel according to a precompiled one mimic it for your wifi card at least. You can check if in fact your card is supported using it's IDVendor and IDProduct on https://wireless.wiki.kernel.org/.

NeddySeagoon, Logicien,
It seems I am unable to turn power saving off, I tried | Code: | modprobe -r iwlwifi
modprobe iwlwifi force_cam=1 |
but it said iwlwifi was in use so I also did and after doing that I did | Code: | modprobe -r iwlwifi
modprobe iwlwifi force_cam=1 |
again.
But when I check I still see that the power_save is enabled. I also tried adding options to /etc/modprobe.d/modprobe.conf. Afterwards I rebooted but it seems the options didn't have any effect.
EDIT:
I just read that modinfo does not reflect any changes made by module options in the config file.
I ran | Code: | | grep [[:alnum:]] /sys/module/iwlwifi/parameters/* | cut -d '/' -f6 |
and this is the output:
| Code: | grep: 11n_disable:0
/sys/module/iwlwifi/parameters/enable_iniamsdu_size:0
bt_coex_active:Y
debug:0
disable_11ac:N
disable_11ax:N
disable_11be:N

fw_restart:Y
led_mode:0

power_level:0
power_save:N

That looks like power sawing off.

I don't think that power saving can be the cause of the Linux errors messages about iwliwfi. Power saving mainly slow reponsiveness after idle. By default power saving is not enabled in the iwlwifi parameters unless you have enable it in your kernel configuration.
Because the kernel complain about iwlwifi you should try an other kernel version on Gentoo and compare the Intel wifi card beheavior on other Linux distributions who used a pre compiled kernel. For example Debian stable who have an older kernel than the the six version. The Arch have the most recent one.
This problem can not be specific on Gentoo but on Linux at all.

It looks like a kernel problem but I am thinking about removing NetworkManager and try netifrc instead.
