I had a similar issue at first. I found a thread with a solution that worked for me, so here is the link and I will also copy and paste the comment that had the working solution:
Download kernel-latest
Dom0: sudo qubes-dom0-update kernel-latest
Maybe not necessary but if you need kernel-latest to make to wifi card work, there are chances that you need it in Dom0 to make the rest of your (recent) hardware work as well.
Download package to make kernel-latest available to AppVMs:
Dom0: sudo qubes-dom0-update kernel-latest-qubes-vm
Stop sys-net
(Setting a Fedora template might be needed, not sure)
Update kernel for sys-net:
Qube Manager → sys-net → Advanced tab → kernel → Select kernel-latest
Set the right kernel options for sys-net:
Dom0:
opt=$(qvm-prefs --get sys-net kernelopts)
qvm-prefs --set sys-net kernelopts "$opt iwlwifi.disable_rxq=1"
Start sys-net. Wifi should now be available.
If this doesn’t work, then I probably won’t be able to help much further because I am also new to Qubes.
