#267146 — D12 Installer does not recognize rtl8xxxu wifi

Dear debian-users,

I put this on a stick and booted it:
debian-live-12.4.0-amd64-gnome.iso

When I boot the live option, the network is immediately loaded and I can
connect to a WIFI network. However, if I use the same stick
(or one with debian 12.4.0 netinst) with the installation option,
the LAN is recognized, but WLAN is not.

If I start a shell from the installer, I can see that the necessary
module rtl8xxxu is loaded (the same one that is loaded in live option).
So I guess it is a firmware issue. How can I get an installer with
non-free firmware (if that is the problem)?
I just found one page that says the (non-free?) FW is always included
in the images (starting from bookworm). Is that true?
Any other idea?

Many Thanks and Best Regards,
Felix

My understanding is that the non-free firmware is now included on
Debian installation media.

I've been using "Debian GNU/Linux 12.2.0 "Bookworm" - Official amd64
NETINST with firmware 20231007-10:28" and had no problems with non-free
firmware on my several computers.

So to diagnose this further, exactly what hardware? Please run lspci,
and run lspci -v for the offending device.

Also, you can run the netinst installer at least through the relevant
installation phase. Then please capture the logs, probably under
/var/log. Searching syslog on the word "firmware" should turn up some
interesting messages.

Does anybody read signatures any more?

hello Charles,

thank you for your reply.

yes, it is pretty clearly stated here:
https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/

As I wrote in the other reply, I was mainly concerned about Wifi not
working after installation (I wanted to understand it). I can install
from LAN.

Many Thanks for the reply,
Felix

Hope I'm wrong, but I've heard that D-I has trouble with USB devices 
other than keyboard and mouse. The rtl8xxxu module is usually for USB 
NIC, if it's the case I think you can rely only to LAN for the installation.

I was mainly concerned with Wifi not working after installation. I
bought a long LAN cable and can install via LAN. Now that I understand
the limitation (a search on google seems to confirm this), I am not
worried any more :)

Many Thanks and Best Regards,
Felix
