[SOLVED] WiFi problem - Intel AC 9260 - iwlwifi-9260-th-b0-jf-b0-34

Hello, I have some trouble with my WiFi card Intel AC 9260 on a Dell XPS 9570.

The output of "uname -r":

4.19.78-2-lts

The output of "ip link":

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s20f0u2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 1000
    link/ether d6:a7:b2:40:27:2c brd ff:ff:ff:ff:ff:ff

The output of "lspci -k":

3b:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)
        Subsystem: Intel Corporation Wireless-AC 9260
        Kernel modules: iwlwifi

The output of "sudo lshw -c network"

I did download the iwlwifi-9260-th-b0-jf-b0-34.ucode firmware since I think it can maybe fix my problem (not sure) but I'm not sure where I'm supposed to install it since I don't seem to have a /lib/firmware/ folder or neither a /usr/lib/firmware/ folder.

Btw, sorry for my poor english, it's not my native language.... I'm still a linux beginner and I'm a brand new Arch linux user (just finished to install it this morning), I know it's not the best distro for a beginner but I think it will be a great one to learn more!

You have to install the linux-firmware package, not necessarily single distinct firmware files.

Oh wow!  Thank you verry much, it work perfectly now!  I did'nt think it was so simple, hahaha, but, do you know why I dont have a /lib/firmware/ folder or /usr/lib/firmware/ ?  The question maybe sound stupid, but I did search on google about it and I found nothing about it... Thanks again!

/lib is a sym link to /usr/lib.  /usr/lib/firmware is supplied by linux-firmware and a few other packages

pacman -Fo /usr/lib/firmware/
usr/lib/firmware/ is owned by core/ipw2100-fw 1.3-9
usr/lib/firmware/ is owned by core/ipw2200-fw 3.1-7
usr/lib/firmware/ is owned by core/linux-firmware 20190923.417a9c6-1
usr/lib/firmware/ is owned by core/wireless-regdb 2019.06.03-1
usr/lib/firmware/ is owned by extra/alsa-firmware 1.0.29-2
usr/lib/firmware/ is owned by extra/linux-atm 2.5.2-6

Hello,

I see that this problem is about iwlwifi drivers in linux-firmware package. There is also a bugtracker entry https://bugs.archlinux.org/task/63117 flagged as closed but it still persists.

I'm using an Intel 9260 card. I couldn't get it working on latest linux-firmware with either 5.6.15 or 5.7.5-zen. Yet, it works with both kernels after downgrading to linux-firmware-20190717.bf13a71. I tried 2020 05 19, 2020 04 21, 2019 12 10 along the way with no success. You need to download corresponding file from https://archive.archlinux.org/packages/ … -firmware/ and install it with pacman -U as directed in the first message in the bugtracker.

For search engine folks, I was getting

Direct firmware load for iwl-debug-yoyo.bin failed with error -2

with dmesg | grep iwlwifi

AND

nl80211: Could not set interface 'wlp2s0' up

with wifi-menu
