[RESOLVED] Wifi stopped working after recent update

Roughly a week ago I updated my system, and since then I have not been able to get wifi to work. Wired networking still works fine. The wifi icon in the Gnome panel is not showing up, and if I click to pull down the settings from the panel the wifi entry is grayed out. If I click select a network, the pop up open and says no networks with a perpetual loading icon. If I do

iw dev wlp3s0 scan

I can see the SSID I am trying to connect to. Running

iw dev wlp3s0 connect <SSID>

does not produce any output. Trying to run wifi-menu simply tells me no networks found. I've tried searching around the forums and the wiki but I haven't had much success. Any help with what to try next is appreciated, I'm stuck dual booting back into Windows until I can get this resolved.

Re: [RESOLVED] Wifi stopped working after recent update

You mention gnome's network management and wifi-menu (which is part of netctl). From the wiki:

Warning: Do not enable concurrent, conflicting network services. Use systemctl --type=service to ensure that no other network service is running before enabling a netctl profile/service.

Please check your setup.

Re: [RESOLVED] Wifi stopped working after recent update

I don't normally use wifi-menu, I just tried it during troubleshooting to see if I would get different results. I don't believe I have any other network services running, unless I missed something. Here is the output of the above command

  UNIT                                                LOAD   ACTIVE SUB     DESCRIPTION

Re: [RESOLVED] Wifi stopped working after recent update

Because of dual booting, see the 3rd link below (mandatory) and if that's not the cause try to disable https://wiki.archlinux.org/title/Networ … domization and if that's still not the cause, please post a complete system journal that covers a failing connection attempt.

Re: [RESOLVED] Wifi stopped working after recent update

Figured it out, here's what I did in case anyone else comes across the same issue.

I tried disabling MAC addressing randomization as you suggested, but it had no effect. I did not think to check/forgot about journalctl, and when I did I saw these lines.

Feb 20 20:37:56 ArchLinux NetworkManager[325]: <warn>  [1645407476.7323] device (wlp3s0): re-acquiring supplicant interface (#4).
Feb 20 20:37:59 ArchLinux NetworkManager[325]: <error> [1645407479.7341] device (wlp3s0): Couldn't initialize supplicant interface: Failed to D-Bus activate wpa_supplicant service

A Google search for the second line was giving results about wpa_supplicant not being installed. I knew for a fact that it was installed, so I tried to reinstall it. pacman -S wpa_supplicant resulted in

error: failed to commit transaction (conflicting files)

wpa_supplicant: /usr/share/man/man8/wpa_supplicant.8.gz exists in filesystem

So I redirected pacman's output to a file, then stripped everything but the filenames and ran

cat pacout | xargs pacman -Qo

All of the files said they did not belong to any package, so I made a temp directory and ran

cat pacout | xargs -I {} mv {} .

then reinstalled wpa_supplicant. After that, I got

ldconfig: file /usr/lib/libembree3.so.3.13.3 is truncated

ldconfig: file /usr/lib/libembree3.so is truncated

ldconfig: file /usr/lib/libembree3.so.3 is truncated

Another pacman -Qo told me that those files belonged to the embree package so I reinstalled that, then reinstalled wpa_supplicant again. Both completed with no errors this time. After that I did

systemctl restart NetworkManager

Now I am happily back on wifi again. Thank you for the help. I am new here, do I need to mark as closed or anything like that?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
