[SOLVED] Wifi Issues after Full System Upgrade (Lenovo Thinkpad T420)

Hey,

after a full system upgrade I rebooted my machine and now I can't use my wirlesss network card somehow.
When using netctl I find this in my journal:

Aug 27 23:08:05 archlinux network[826]: Starting network profile 'home'...

Ethernet works though and I tried mainstream, lts and zen kernel, same results.
With strace and wpa_cli I managed to find this out:

wlp3s0 (my wireless card) refuses the connection to its socket. I don't know if this is a useful information ...

'iwlwifi' is loaded so hmm...
I googled a bit but can't find any solution regarding this.

I am running a lenovo thinkpad T420:
Linux archlinux 4.9.45-1-lts #1 SMP Fri Aug 25 20:38:26 CEST 2017 x86_64 GNU/Linux


Thanks for helping.

Re: [SOLVED] Wifi Issues after Full System Upgrade (Lenovo Thinkpad T420)

Hi,

i had just a similar problem (after pacman -Syu this saturday - i had no wifi - but also no ethernet). After spending part of the weekend (and giving up) i now found a solution - at least for me:

By downgrading netctl-1.13-2 (was installed by the upgrade) to the older netctl-1.12-2 package i had.

It seems easy to try. I hope that it could resolve your problem too.

PS
Running 4.12.8-2-ARCH on a T450s

PPS
I was trying a lot of stuff before (downgrading the kernel and the firmware, etc...)

PPPS
I was rather puzzled. I was able to scan the access points but if i tried to connect netctl (reported a timeout error). Setting up the connection manually also didn't help.

Tried downgrading, still not working. I will look at this in detail tomorrow and post a solution if I find one. Thanks anyway smile

Re: [SOLVED] Wifi Issues after Full System Upgrade (Lenovo Thinkpad T420)

So finally it is working again and I am not quite sure why ...
So I tried many things, but netctl is just not working as it is right now.
With wpa_passphrase and wpa_supplicant I got it up and running again.

wpa_passphrase <SSID> <PASS> >> /etc/wpa_supplicant/home.conf
wpa_supplicant -B -i <INTERFACE> -c /etc/wpa_supplicant/home.conf
dhcpcd <INTERFACE>

When running netctl I get the same error as above:

I will mark this as solved, altough netctl is broken when using this driver ...

So I tried many things, but netctl is just not working as it is right now.
With wpa_passphrase and wpa_supplicant I got it up and running again.

I'm just curious:
So it seems that netctl and iwlwifi used together are broken. I guess this could affect a lot of laptop users (at least with intel wifi).
Since i never did that, i am clueless how and where to do it, but should a bug be reported?

Maybe I am just too stupid to use netctl, but you are right. My script once worked and now it doesn't ... 'just not using netctl' won't solve the problem ...
I will report this as a bug. Thanks g8ntly for helping.

Bug added https://bugs.archlinux.org/task/55456

i had just a similar problem (after pacman -Syu this saturday - i had no wifi - but also no ethernet). After spending part of the weekend (and giving up) i now found a solution - at least for me:
By downgrading netctl-1.13-2 (was installed by the upgrade) to the older netctl-1.12-2 package i had.
It seems easy to try. I hope that it could resolve your problem too.

Yes, this works. I tried this, but forgot to do a 'systemctl daemon-reload'.

Re: [SOLVED] Wifi Issues after Full System Upgrade (Lenovo Thinkpad T420)

I was reviewing this again and luckily found in your bug report a `solution` (or horrible workaround):
https://bugs.archlinux.org/task/55456

Last year systemd started to waste 30 seconds on every shutdown ("stop job running for ..."). So I googled and modified this in my '/etc/systemd/system.conf':

DefaultTimeoutStartSec=1s
DefaultTimeoutStopSec=1s

Turns out I did the same thing (now) 2 yrs ago! Also by the same motivation big_smile
So setting them to 5s worked for me too.

Thank you onixion and jouke!
What a nice bug... **cough
