WiFi driver help

My WiFi chipset that’s built into my motherboard isn’t supported by Qubes out of the box. While reading the Qubes FAQ, this recommendation is provided.

"In a terminal in your net Qube template, run the command sudo dnf install linux-firmware and then restart your net Qube.

When I do this, my net qube terminal responds with the error

Unable to detect release version (use ‘–releasever’ to specify release version)
Error: There are no enabled repos in “/etc/yum.repos.d”, “/etc/yum/repos.d”, “etc/distro.repos.d”

Is this because my net qube is Debian instead of Fedora? Or is this command old and no longer accurate?

Is there any other simple way for me to download wireless drivers?

Thanks in advance for any help!

Dnf is for Fedora. For Debian install this:
sudo apt install firmware-iwlwifi
If it’s a new WiFI chipset then you may need to install a newer firmware version from backports.
