[SOLVED] wifi does not work after update to linux 6.17.1

`ip link` now only shows 'lo' and completely does not show wifi. ping says that it cannot connect to the domain when i do `ping google.com`. i have downgraded back to 6.16.10 (linux and linux-headers) for now, which is how i got the output below.

dmesg output on 6.17.1:

i have found the exact iwlwifi-Qu-c0-hr-b0-77.ucode.zst in /lib/firmware/intel/iwlwifi/iwlwifi-Qu-c0-hr-b0-77.ucode.zst, so i have no idea why 6.17.1 shows no suitable firmware found.

i noticed that mkinitcpio also shows errors when building:

when mkinitcpio built 6.16.10, there were none of these errors, only warnings which i have seen is normal.

i have also tried https://bbs.archlinux.org/viewtopic.php?id=298525 and read through the whole thread, running `sudo depmod -v -a 6.17.1-arch1-1` and running mkinitcpio again still gave the errors.
i have tested this on linux 6.16.8, it had no issue either.

Re: [SOLVED] wifi does not work after update to linux 6.17.1

==> ERROR: module not found: 'snd_hda_codec_realtek'
Seems now /usr/lib/modules/6.17.1-arch1-1/kernel/sound/hda/codecs/realtek/snd-hda-codec-realtek-lib.ko.zst

The firmware is likely missing from your initramfs - please post your mkinitcpio.conf

Re: [SOLVED] wifi does not work after update to linux 6.17.1

So you're putting iwlmvm into the initramfs but not iwlwifi?
Is there any specific reason for this, let's call it "custom", approach and not just relying on "udev autodetect" and only adding extra modules you specifically want extra into the MODULES array?

Re: [SOLVED] wifi does not work after update to linux 6.17.1

uh, i tried to remove udev to reduce initramfs size. however, even when adding udev autodetect to HOOKS and iwlwifi to MODULES, mkinitcpio still gives the same error - and snd_hda_codec_realtek, sha512_ssse3, and sha1_ssse3 are definitely in MODULES, yet mkinitcpio still gives an error.

if i need to use the original mkinitcpio.conf, let me know how i can regenerate it.

Re: [SOLVED] wifi does not work after update to linux 6.17.1

snd_hda_codec_realtek, sha512_ssse3, and sha1_ssse3 are definitely in MODULES, yet mkinitcpio still gives an error

s/yet/hence/g

Remove the entire MODULES array and add the autodetect hook, then regenerate the initramfs.
You can then inspect the initramfs to update the modules array ifff you insist on manually curating it (which seems needlessly laborious? )

Re: [SOLVED] wifi does not work after update to linux 6.17.1

i have decided to use the default mkinitcpio.conf, which i got from unpacking mkinitcpio package in /var/cache/pacman/pkg and replacing the conf file i had before. this fixed the problem of both the wifi working and errors in the config. thank you everyone!
