Wifi stopped working on kernel 6.11.2-1.fc37

Hardware: @novacustom NV41

I use kernel-latest with all my qubes. This morning, the dom0 as well as all the qubes got a kernel update. On this new kernel 6.11.2-1.fc37 (kernel-latest, I guess), sys-net’s NetworkManager xfce tray applet doesn’t show any wifi connectivity, only shows ethernet connectivity.

In order to get wifi connectivity back, I had to move back the kernel to 6.10.10-1.fc37.

@marmarek Is kernel-latest still required for the NV41 Series? Because I don’t think so, but how can we know when it is and when not?

I am using kernel-latest just for “fun”, not necessarily due to a requirement with NV41 hardware in particular.

On NV41 it shouldn’t be required, standard 6.6.x kernel should have everything needed on NV41 (but not V5xx)

What about the issue at hand that I wrote in my OP? I am a bit new to kernel-stuff – when 6.11 becomes the “new” 6.6 (ie, today’s kernel-latest becoming tomorrow’s normal kernel), am I (and other NV41 users) going to have defunct wifi?

Ideally, this should be reported on Github before it becomes the default :wink:.

I’m not sure about the original issue here (in our tests wifi works on NV41 with 6.11.2 too). Can you share sudo dmesg output from sys-net?

As for kernel versions - the “kernel-latest” package tracks latest stable kernel (as listed on https://kernel.org/). The “kernel” tracks most recent “longterm” kernel. We make the switch with some delay to get more testing. And then the old “kernel” gets renamed with version suffix. So, when new longterm will get promoted to “kernel”, the current 6.6.x will remain as “kernel-66” (if somebody prefers to keep using that branch, they will need to manually install this package). We keep providing updates to old branches too.

I will do so the next time I sit down in front of the laptop for this purpose (currently working, and I need wifi).

So, the gist is, either I have a specific hiccup (your tests show that 6.11 works for wifi), OR, the longterm kernel version of the future will have a stable wifi firmware, than what it currently has.

Installing firmware-iwlwifi from bookworm-backports solves this problem. See here: No network after upgrade: iwlwifi not loading - #4 by tanky0u
