Hi all,
I just bought a new HP Probook 455 G9 and did a fresh install of Fedora Kinoite 36.
Everything works fine, except for the wifi adapter.
I made all possible updates but no wifi is shown.
Following the output of lspci -nn:

You probably need to install the driver for your wifi. I believe they’re here:

Ok, thanks, I’ll try.
Just for curiosity, why these drivers, aren’t already merged into the kernel?

I’m not sure really. Manufacturers need to contribute drivers to the kernel. It does look like some chipsets are already supported now, but perhaps the one your system has isn’t?

More links:

The first step would be to check if your chipset is supported by the kernel. If it is, then we need to see why it isn’t working. If it isn’t, we need to install the drivers.

I think that the chipset is not yet supported by the kernel.
I found a link, updated on 14/10/2022, from the kernel.org site, that talks about that.
[4/4] wifi: rtw89: 8852b: add 8852be to Makefile and Kconfig - Patchwork
Hopefully it will be supported soon.
However thanks for your advice!
