firmware-realtekRealtek RTL8852BE wifi firmware

[MintMagoo]

When I installed Debian Bookworm 12.7 my wifi did not work. I ended up backporting kernel 6.9.7+bpo-amd64.

I was wonder if I reinstall bookworm and install firmware-realtek I can avoid using the backported kernel?

Looking throuh the list I see:

/lib/firmware/rtl_bt/rtl8852bu_config.bin
/lib/firmware/rtl_bt/rtl8852bu_fw.bin

But nothing for RTL8852BE.

It looks like the answer is no. Backporting kernel 6.9.7+bpo-amd64 is by far the easy solution.

To be clear, did you actually backport the kernel yourself, or install one from the backports repository?
Those are two different things.

deb http://deb.debian.org/debian bookworm-backports main contrib non-free non-free-firmware

sudo apt -t bookworm-backports linux-image-6.9.7+bpo-amd64 linux-headers-6.9.7+bpo-amd64

I am guessing that means from the repository. When you say "backport the kernel yourself", I am guessing that means compiling from source code, which is over my head. Is that correct?

Actually I followed the steps in the second link you gave. I created rtw89-dkms_1.0.2-3_all.deb on a VM. Installed debian-12.8.0-amd64 on the real host and then rtw89-dkms_1.0.2-3_all.deb.

It works without secure boot. But does not load when secure boot is on.

I tried to figure out how to create a mok for it but found multiple instructions and am too confused which, if any apply. And what the possible ramifications are, if there is a possible negative as compared to linux-image-6.9.7+bpo-amd64 which does support secure boot.

So I backed up what I had and restored to bookworm w/ linux-image-6.9.7+bpo-amd64.
