[SOLVED] HP Pavillion 15 - WiFi suddenly disappears, doesn't come back

Model: HP Pavillion 15-eg1015nm
Sorry for bad English in advance, it's not my native language.
So I am a Arch newbie, recently installed Arch on my HP Pavillion and everything works fine except WiFi.
It worked actually pretty reasonably while installing Arch, but for some reason it stopped after. Not immediately, it actually stopped working after random time, at least I can't find the cause so for me it's random.
I haven't tried Ethernet, as I don't have a sufficient port on my laptop, nor an adapter for it.
System was up to date at the point of WiFi dissapearing (updated several minutes before last WiFi dissapearance), after that I tried some things to fix it but nothing worked, so I reverted to my first btrfs snapshot but the issue still persists, but I had WiFi to install some fonts. Still, I did nothing significant to my system for it to react in a such way.
I checked some system logs but I am not sure if I hit the point with commands I was using for them. I am also not sure if i know to read them well, so any help is appreciated. I haven't found there anything significant.
Also, I don't know if it is important for solving the issue, but I use SwayWM, so I use Wayland protocol.

I fixed it for now with these commands (but I don't know if WiFi will again suddenly dissapear in the future):

sudo systemctl restart NetworkManager
sudo rfkill unblock wifi
nmtui

Should I mark it as [SOLVED]?

WiFi hasn't disaapeared for more than a day so I will mark it as solved. If any issues persist I will write new post and this one I will mark as [SOLVED].

I know you marked this as SOLVED.  But, do you dual boot Windows?  If so, ensure you have turned off fast boot in Windows: https://wiki.archlinux.org/title/Dual_b … ibernation
It can fight with you over WiFi settings such as RFKILL

I don't dual boot Windows. Today I had the same issue with WiFi and I solved it using above mentioned rfkill method, though I am not sure if restarting NetworkManager.service actually solved it. Maybe it had to do something with sof-firmware package, now that I installed it as I saw it missing in journalctl logs I'll see if it will solve it permanently or not at all.

Re: [SOLVED] HP Pavillion 15 - WiFi suddenly disappears, doesn't come back

sof-firmware is for your audio chip - next time the NIC "disappears", just check the status of "rfkill" and "ip a" and b/c of

It worked actually pretty reasonably while installing Arch, but for some reason it stopped after. Not immediately, it actually stopped working after random time, at least I can't find the cause so for me it's random.

and there's no actual metric for "disappear" given in this thread:
Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

There're at least no conflicting services.
As for your sound issues, it's not very likely that changing to pulseaudio is gonna fix anything.
If the problem remains, please open an new thread about that and for a start, post a complete system journal and the outputs of "aplay -lL" and "amixer -c0" and "pactl list sinks"

I will do as you said. For the sound issues, reinstalling sof-firmware solved the issue, that's why I edited message to remove that unecessary part.
