Re: no wifi after upgrade

https://wiki.archlinux.org/title/Tethering

Then you'll have to figure what happened, but my guess would be the firmware split?
Otherwise the common cause of "update, reboot, no wifi" is that you forgot to mount the /boot partition and end up booting an old kernel, lacking most modules.

uname -a
pacman -Qs kernel

Re: no wifi after upgrade

It will hopefully list the kernel packages as well…

I can't really see too good these days … I  can't type it al

Do you have a phone? => In doubt link a picture of the output, but even better: see whether you get network via tethering.

And then also

pacman -Qs firmware

Re: no wifi after upgrade

I'm typing this on an arch setup I use normally for backup and things,
and it's almost as updated.  I wonder if there is some way I should know how to look for what is different from this and my main machine.  This one is barely squintable and sure I could hook it to the tvs and things but that seems like the wrong direction.

One is broken and the other isn't … this isn't going anywhere.
Post the journal of the broken system, if you can't get tethering to work

sudo journalctl -b > /tmp/journal.txt

copy /tmp/journal.txt to some usb key and post it from the system w/ functional internet.

Re: no wifi after upgrade

I think you missed a critical part of the update command in the news. You were supposed to reinstall linux-firmware.

Thanks, that was it. Missed it when I copy/pasted the commands.

Re: no wifi after upgrade

I was mentally not able to produce the appropriate logs I am entirely sorry, but somehow, removing linux-firmware has got me back online.  Got a lot of catching up to do.  I blame nvidia.  for everything wrong in this world.

Re: no wifi after upgrade

???
Did you also remove all dependencies, ie. linux-firmware-intel etc et pp?
Otherwise this might just have triggered an initramfs rebuild?

Re: no wifi after upgrade

no I have done nothing further.  the update thing I keep on waybar says 34 updates.  I should probably fix this more properly I am just so happy to be back online I don't want to break anything now.  But as you have helped me 2 or 3 times over the years I def defer to your judgment..

Re: no wifi after upgrade

pacman -Qs firmware
lspci -k

If you're worried about the next update, post the according tail of the pacman.log

Re: no wifi after upgrade

0000:00:14.3 Network controller: Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01)
	Subsystem: Intel Corporation Dual Band Wi-Fi 6E(802.11ax) AX211 160MHz 2x2 [Garfield Peak]
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi
…
local/linux-firmware-intel 20250613.12fe085f-5
    Firmware files for Linux - Firmware for Intel devices

But all firmware packages are installed - linux-firmware wasn't "removed".
What makes sense.

Re: no wifi after upgrade

If anything bad happens, the pacman log will only contain that after the update.
Updating the provided list of packages seems innocuous enough…
