You saved my life … Didn’t even know that one could install a previous kernel on Tumbleweed.
Network detection is functional again, which confirms the issue was related to the bug in 6.14.
Many thanks to everybody and have a great day.

I have found in dualboot environments that some network cards don’t work during first boot of the linux system.
Works in windows → shutdown
Boot linux → does not work
Reboot linux → wifi works
I don’t know why, but maybe windows leaves the network card in some weird state which makes the kernel think its not working during boot, and its not attempted to check that again - until it’s reset by next shutdown->boot
@Voronamanga Hi are you using systemd-boot on this Tumbleweed setup?
There is a chance that I’ve got same problem with 6.14.x (including fresh 6.14.3) and also with same Network controller: Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01).
Quick workaround is usage of the kernel-default-6.13.x.
There is a chance that it is somehow related to bugzilla.kernel but for me the 6.14.3 is not solving anything and probably not only for me (Fedora)
No “systemd-boot” in use.
Hi, I’ve already seen such issues, many years ago, so I think you’re probably right, there is a possibility that Windows can alter the state of the card and then it doesn’t work on Linux, and maybe a second boot reinitialize it.
But in the present case, it seems really related to a bug in kernel 6.14. AFAIK.
@malcolmlewis MMh no, I’m almost 99% sure I don’t.
And BTW it’s something you have to install, I haven’t done it, so definitely no.
Would it be helpful ?
@Voronamanga It was just an observation as it’s something I encountered on Aeon and iwlwifi module.
OK. Actually it is not really solved since new kernel (6.14.3 ?) doesn’t seem to bring a fix (I haven’t tried it myself, but that’s according to premboj).
It is in 6.14.4 (see ChangeLog-6.14.4 and search for iwlwifi).
6.14.4 resolved it for me.
Yep, Network controller: Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01) works again 
@Voronamanga
Yep too ! 
I just updated the kernel to 6.14.4-1-default and no need to go back to 6.13 any more.
