For the wireless firmware, read the commands I used as a general guide, but be sure you understand what you are doing when you mv and cp.
This command will tell you the info you need to identify your wireless card, and what firmware is currently in use:
sudo lshw -C network
Then go to the Intel website, I think the one applicable to you is the one for the 9461, 9462 and 9560:
iwlwifi-9000-pu-b0-jf-b0-34.618819.0.tgz

There's a bug report on a similar problem from last year here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1864188
There is a mention of firmware versions there, especially see the last post which might be helpful, although neither of those is the same as the Intel firmware, although a file of the same name as all 3 options is in the firmware package. Who knows what gets loaded as standard, use lshw to find out and try some stuff.

Yes, that's about what I got after I mv'ed all the iwlwifi stuff out of /lib/firmware, so no firmware at all was loaded. Try getting the Intel firmware, untar it (there are some instructions in the README in there with it too) then put the relevant file in /lib/firmware after temporarily mv'ing any other iwlwifi stuff to a backup location, so the driver has no choice what it loads (the driver chooses the first available on it's preference list) and reboot.

@julianmarcos ,
can you please share your /etc/mkinitcpio.conf?

Code: [Select]

lspci -nn

to see which exatly ID you have

you can try add your fw (if you sure which fw exactly) to mkinitcpio to load this file before start boot.

add it in /etc/mkinitcpio.conf into section FILES:

FILES=(/usr/lib/firmware/iwlwifi-9000-pu-b0-jf-b0-34.ucode) but i think according to some clues your fw is /usr/lib/firmware/iwlwifi-9000-pu-b0-jf-b0-38.ucode

creating new mkinitcpio:

Code: [Select]

mkinitcpio -p linux

ID says, your wifi card is Intel® Wireless-AC 9462
https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html say, it need this firmware:
https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-9000-pu-b0-jf-b0-34.618819.0.tgz

can you please extract iwlwifi-9000-pu-b0-jf-b0-34.ucode from the tgz file an replace the another iwlwifi-9000-pu-b0-jf-b0-34.ucode file in /usr/lib/fimware?

after shut down your computer, wait, and start it again (cold reboot)

To rule out BT causing this problem, many recommend disabling the BT module:
add

Code: [Select]

blacklist btusb

Code: [Select]

/etc/modprobe.d/blacklist.conf

create file blacklist.conf if not eist.

since your wifi doesn't work in other distributions either, as you said, so I see it more on the HW issue.
