[SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

I recently updated all my packages and my kernel version went from 6.6.1 to 6.6.4. For some reason, on any kernel from 6.6.2 onwards, my laptop's internet just doesn't work. Ethernet is just not detected, WiFi doesn't connect, and there were a few other weird issues. I'm able to use it now by downgrading the linux package to 6.6.1 (yes I know partial upgrades are bad but I need to be able to use my laptop).

I'm using gnome 45 (NetworkManager) with secure boot with sbctl, systemd-boot, gdm and plymouth.

Looking at journalctl and booting without plymouth and quiet, I see NetworkManager failed with exit code and failed to start accounts service. Trying to restart the failed services just waits indefinitely.

Here's a list of everything I observed that may or may not be relevant.

• I've had a message like "Failed to start Virtual Console Setup" show up before plymouth for a few months but now it shows the message twice. I never bothered trying to fix it before because it was just a mild annoyance but it would be helpful if anyone could tell me how to fix it.

• Ethernet shows "Cable disconnected" and clicking the WiFi toggle does nothing.

• There are a lot of empty pills in gnome's quick settings panel, as in the pill has no text and is just grey and unclickable.

• Dark theme isn't respected by some applications.

• It seems to take longer to boot

Let me know if you need any more info. Any help is greatly appreciated, I really need this laptop to work without issues. Thanks in advance.

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

Please post your complete system journal for a boot w/ a newer kernel, eg.

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

for the previous ("-1") one.

Does "rfkill" remain in that state?
Can you alter it w/ the systems HW radio switch?
Is there a parallel windows?

Ethernet shows "Cable disconnected"

Would you expect differently? There's no hit for a carrier

ethtool enp0s31f6

I'm not sure what you mean. I'm not using dual boot and pressing the wifi button on my keyboard does nothing.

Well my ethernet cable is plugged in right now and I've never had a problem with it before. Here's the output of `ethtool enp0s31f6` (on the older kernel).

I'm not sure what you mean.

I mean "type rfkill into a terminal and check the output state"

Edit: Ok, the link is clearly there.

Well my ethernet cable is plugged in right now

ethtool enp0s31f6

And is there any NM profile for the wired connection? Resp. did you disable the NIC?

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

Here's the journalctl for the good kernel: http://0x0.st/HxCR.txt

Here's rfkill for —

good kernel:

ID TYPE      DEVICE                   SOFT      HARD
 0 bluetooth tpacpi_bluetooth_sw unblocked unblocked
 2 wlan      phy0                unblocked   blocked
 4 bluetooth hci0                unblocked unblocked

Bad kernel —

ID TYPE      DEVICE                   SOFT      HARD
 0 bluetooth tpacpi_bluetooth_sw unblocked unblocked
 1 bluetooth hci0                unblocked unblocked
 2 wlan      phy0                unblocked   blocked

`nm-connection-editor` is completely empty on the bad kernel but has all my saved wifi networks on the good kernel.

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

The "good" kernel has iwlwifi crash and you connect via the wired NIC - adding "module_blacklist=iwlwifi" to the https://wiki.archlinux.org/title/Kernel_parameters will likely result in the status quote ante?
But that's oc silly:

ls -lR /etc/NetworkManager/

There should™ be some system-connections and config file(s)
Also

sudo nmcli connection

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

sudo nmcli connection

This works fine on the good kernel and lists all my saved networks. On the bad kernel, it shows this after a few seconds.

Warning: nmcli (1.44.2) and NetworkManager (Unknown) versions don't match. Restarting NetworkManager is advised.
Error: NetworkManager is not running.

I've tried restarting NetworkManager before but all it does is wait indefinitely with no output.

ls -lR /etc/NetworkManager/

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

The big red flag is the second session bus on the "bad" boot - it doesn't show up in the jorunal though, nor any reason why you'd get a second bus.

Did you try whether simply blacklisting iwlwifi "helps" (just so we're not chasing a wild goose here)

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

Blacklisting iwlwifi makes the ethernet work on the "bad" kernel and it doesn't seem to take too long to boot. Unfortunately it's not 100% fixed. Now gnome settings says "No Wi-Fi adapter found" but `sudo nmcli connection` shows my saved networks correctly. It still shows "Failed to start Virtual Console Setup" on boot though.

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

systemctl status systemd-vconsole-setup.service

though w/

Dec 06 13:56:48 archlinux systemd-vconsole-setup[136]: /usr/bin/loadkeys failed with exit status 1.

I guess there's some bogus entry in /etc/vconsole.conf?

That should be unrelated to the iwlwifi/NM issue, though.
The gnome settings message would be correct and expectable (you blacklisted the wifi chip)

1. what are the contents of /etc/NetworkManager/system-connections
2. what if you remove all your wifi connection profiles (or at least move them out of sight)?

It has all my saved networks.

2. what if you remove all your wifi connection profiles (or at least move them out of sight)?

I removed iwlwifi from the blacklist and tried clearing the directory but it didn't do anything differently. I selected my WiFi and entered the password but it just showed the spinner indefinitely. Connecting my ethernet after that didn't work and also completely disabled WiFi even if I disconnected the cable (the WiFi toggle did nothing).

Re: [SOLVED] Network doesn't work on ThinkPad L480 on kernel 6.6.2 and up

Did you get any kernel/iwlwifi/networkmanager errrors for trying to connect to the wifi AP?

To isolate whether the problem is the kernel or NM, install netctl, disable networkmanager, reboot and try to connect w/ wifi-menu (or a wired netctl profile or just run dhcpcd)

Ethernet works fine with netctl without blacklist iwlwifi but I couldn't get WiFi to work. It's possible that my netctl profile config is wrong for wireless but I'm not sure. Either way, disabling NetworkManager fixes all the other issues like the slow boot and weird dark theme issues. The culprit is almost definitely NM but I don't want to switch to something else because I want to be able to configure my network through gnome settings.

Just for reference, here's my netctl wireless-wpa profile.

Description='A simple WPA encrypted wireless connection'
Interface=wlp6s0
Connection=wireless

Security=wpa
IP=dhcp

ESSID='REDACTED'
# Prepend hexadecimal keys with \"
# If your key starts with ", write it as '""<key>"'
# See also: the section on special quoting rules in netctl.profile(5)
Key='REDACTED'
# Uncomment this if your ssid is hidden
#Hidden=yes
# Set a priority for automatic profile selection
#Priority=10

Did you generate it w/ wifi-menu?
What is the profile status and do you get any journal messages when attempting to access to the AP w/ wifi-menu?

When removing all WiFi profiles from NM, do you get a wired connection (and does the system otherwise behave as expected)?

Nevermind that was my mistake. I generated the WiFi profile with wifi-menu and everything worked correctly with netctl (both ethernet and WiFi).

I also tried booting the bad kernel with NM (and netctl) disabled and manually starting the service after login. Doing that causes the command to just wait indefinitely and I didn't see anything relevant in the journal.

So status quo is that the "bad" kernel works w/ netctl on all NICs but NM remains broken (even after removing all profiles) unless iwlwifi is blacklisted on the "bad" kernel?

1. same w/ a fresh user profile (to get some misconfiguration out of the way)
2. try to disable https://wiki.archlinux.org/title/Networ … domization

Neither of these did anything.

If you boot w/ NM disabled, what's the state of "rfkill" before and after enabling/starting NM?
Edit:

Doing that causes the command to just wait indefinitely and I didn't see anything relevant in the journal.

and certainly post the journal tail for that as well.

Here's rfkill with NM disabled both before and after I manually start the service on the bad kernel.

ID TYPE      DEVICE                   SOFT      HARD
 0 bluetooth tpacpi_bluetooth_sw unblocked unblocked
 1 wlan      phy0                unblocked   blocked
 2 bluetooth hci0                unblocked unblocked

Here's the journal: http://0x0.st/H3uM.txt

So phy0 remains hard-blocked, are you sure you can establish a wifi connection w/ netctl and what does the rfkill state look afterwards (also "ip a")?

Do you have a hardware radio switch on the notebook?
Fn+F5?

No journal so far has shown the wifi chip to function at all.
Try to use it from some live distro (grml, ubuntu, …) to see whether the HW is maybe fused.

Ah that was my mistake. The ethernet cable was plugged in most of the time and I forgot to unplug it and test. rfkill shows evertything to be unblocked when I unplug the cable.

I tested this time with NM disabled. When I boot with ethernet unplugged and start the service, WiFi actually connects successfully and actually works. But when I plug in the ethernet cable the network immediately dies and I see this icon in the top bar. Neither ethernet nor WiFi work at this point until I restart. The settings page says NetworkManager is not running even though systemd says it's active.

The journal actually seems to contain some relevant information this time: http://0x0.st/H3S7.txt
