Possibly all you need do is install the firmware package,
firmware-realtek, from Debian backports. https://backports.debian.org/

Booting UEFI vs. BIOS should not be relevant here.

Odd. There is a more recent version of the realtek firmware package in backports. https://packages.debian.org/search?searchon=names&section=all&suite=all&arch=any&exact=0&keywords=firmware-realtek

I know zilch about synaptic. Try the apt or apt-get instructions at https://backports.debian.org/Instructions/#index3h2

Try stealing the firmware file from the ubuntu installation and
placing it in Debian's /lib/firmware/rtw88/ yourself.

I booted from the Ubuntu USB stick and copied

rtw8822c_wow_fw.bin.zst

This is why I suggested the backport rather than copying in the file.
Please back these changes out, then try the backport (using apt or
apt-get, as the instructions indicate). If that doesn't work, try the
backport kernel.

Add a repo as you would for apt-get or aptitude;

deb http://deb.debian.org/debian bookworm-backports main

to /etc/apt/sources.list

or as a file in /etc/apt/sources.list.d/

I tend to put Debian repos in /etc/apt/sources.list, leaving the /etc/apt//sources.list.d/ for external repos. Of course, it makes
little difference in practice.

In Synaptic, there is a Repositories menu entry under Settings, where
new entries can be made and existing ones disabled, matching the
commenting in sources.list.

Yes there is.

Yet I /still/ find it easier to create the repos in a text editor and
save them in the correct place.

'To each, their own' as the saying goes.

I've never done it that way, either, I only ever use Synaptic to help
clear dependency logjams in sid, and nothing ever needs changing there.

Lee,

I do not have a solution for you, but as you likely found via
Internet searches, you are not alone in having issues with this
Realtek device/driver.


Like you suggested, I too once installed Linux Mint Ubuntu to a laptop
to get over hardware issues.


Hopefully the Realtek driver developers will rectify the issue.

All I can suggest is to try backports to get the latest Debian package
(but I saw that others have already suggested this):

If backports is not in your apt sources, then add the following lines:

# nano /etc/apt/sources.list

# bookworm-backports, previously on backports.debian.org
deb https://deb.debian.org/debian/ bookworm-backports main contrib
non-free non-free-firmware
deb-src https://deb.debian.org/debian/ bookworm-backports main contrib
non-free non-free-firmware

# apt install -t bookworm-backports firmware-realtek


# export PATH=$PATH:/usr/sbin
# update-initramfs -u

# systemctl reboot


However if the Debian backports realtek network driver version is
still currently faulty, then this will not solve your network issues.

If you need a missing firmware, instead of getting it from ubuntu, get it
from the source :) https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtw88/

I'm not seeing an updated realtek firmware in backports:

Here I have this one

# dpkg -l firmware-realtek
ii firmware-realtek 20240709-2~bpo12+1 all Binary firmware for Realtek wired/Wi-Fi/BT adapters

To install it you can try (after adding backports to sources)

apt -t bookworm-backports install firmware-realtek

dists will take you to the Packages files, whereas you want
pool for the .deb files themselves. Or just go to:

where you can tell which .deb belongs to what suite.

That's getting hard to discern. AIUI the OP got the latest firmware

Lee,

I do not have a solution for you, but as you likely found via Internet searches, you are not alone in having issues with this Realtek device/driver.

Like you suggested, I too once installed Linux Mint Ubuntu to a laptop to get over hardware issues.

Hopefully the Realtek driver developers will rectify the issue.

It seems like somebody has fixed whatever-it-is because if I boot up
Ubuntu I don't have any problems with wi-fi.

All I can suggest is to try backports to get the latest Debian package (but I saw that others have already suggested this):

I'm trying but it's not working for me :(

If backports is not in your apt sources, then add the following lines:

It seems like I should see the 2024 version of firmware-realtek but no.

From my own personal experience, Debian backports are not always at the latest version, so I am not surprised you did not find "the 2024 version of firmware-realtek".

Sadly I don't know of a way to have Debian safely use the latest version for you to test.

I had an issue with a fairly new RADEON video card, for which I had to use AMD's Ubuntu drivers in Debian, or install Arch Linux. I was unable to get Debian drivers to work for this Video card. Maybe by the time Trixie gets into Stable, my RADEON video
card will be supported? I am currently using Arch Linux on this PC and using it as a test case, until Trixie is released to stable.

If you are able to do this, I could suggest installing Arch Linux (a rolling distribution that tends to use the latest drivers) as a test. It seemed quite stable from my usage, however I do favour whatever is the current stable version of Debian. Just
sometimes I have had to use Linux Mint Ubuntu or Arch Linux to get a particular piece of hardware to work with Linux. I expect if I was smarter, I would have succeeded in getting Debian to work with my hardware.

If you do try Arch Linux to see if WIFI works well in different rooms, then I recommend using the archinstall script. Even using archinstall it took me a few installations before I worked out what to select for the installation. But I think you may have
tried this with Ubuntu already? (and found WIFI works from all your rooms?) If you have that would be proof the latest version of the Linux Realtek drivers do work.

https://wiki.archlinux.org/title/Archinstall
(During the archinstall script I added "kde-applications packagekit-qt6 fwupd firewalld" in the "Additional Packages" step. And when the installation was complete, I ran "pacman -Syu")

Wifi keeps disconnecting. Using rtw_8822ce

"It seems you have done quite a bit of searching.
What you may not have noted is that there are several threads here about problems with the rtw_8822ce driver and the cards it supports (poorly it seems) in linux.

I mostly missed them.. very little of what I've seen was for Debian

Most seem to have replaced that card for a fix.

With something other than a realtek - correct?
I _really_ don't want the hassle of using a USB dongle for wifi and
this laptop doesn't look like _anything_ inside the case is easily accessible.

I called Lenovo tech support - they offered to help me get Windows reinstalled and troubleshoot from there, but they flat out don't
support Linux in any way, shape or form.

I would strongly suggest that you either replace that card or get a second card (maybe even a usb dongle) that is better supported so you do not have to fight with the realtek issues."

You might be right, but I'm not willing to give up just yet.

Er, that is not my suggestion, it was a comment I quoted from link I found from a Fedora site. I quoted that comment as it seems Debian is not the only distribution that has issues with that particular RealTek driver. RealTek hardware and drivers have
been an issue to me on many an occasion over the years, in both Windows and Linux. I prefer to use Intel hardware where possible, sadly sometimes RealTeck is what is provided and we have no choice.

All the best with your issue, it is a difficult one. Maybe patience and wait for a fixed RealTek driver to filter down to the current version of Debian Stable will end up being the solution? But that does not sound like a great solution.

George.

Thanks

Correct.
I got the firmware from the Ubuntu Live USB stick - where wireless
works on the laptop.
Reboot into Debian and wifi is broken again.
Then I reverted that set of firmware and got the latest from
backports, but that does not fix the problems with wifi either.

I also got the latest linux-image-amd64 from backports -- but again,
wifi is still mostly broken in Debian.
"mostly broken" because as long as the laptop in within about 6 feet
of the AP wifi works. Take the laptop into a different room & there's
no indication I can see (but what do I know?) that wifi quit working
but I can't ping anything else on the subnet -- not even the AP. And
getting the list of available SSIDs is hit or miss - mostly miss with
having to wait minutes before any of "my" SSIDs shows up on the list
again.

& for the heck of it, I've booted up a live image of Mint; it's the
same deal as Ubuntu, wifi just works.
So getting this realtek card to work correctly all the time is a
solved problem. At least in ubuntu/mint, so what magic do I need to
get it working in Debian???

perhaps a whole kernel would be better.

What's the difference between linux-image-[version #]-amd64 and a whole kernel?

Nothing, as long as there's a version number there. (There's
a version-less package that depends on the latest version,
which is a trick to make APT aware of a kernel upgrade.)

I'm only skimming the thread as, with my old hardware devices,
I tend not to see these problems. Looking back at your post of
14 Oct 2024 13:55:25, I see that you have indeed installed the
backported kernel. I also see that your firmware listed there is
under /lib/firmware/ instead of /lib/firmware/rtw88/, but
presumably you've corrected that if needed.

Whether there's a difference in the drivers between Debian and
ubuntu/mint, IDK. There may be clues in the web posts on the
topic of this card elsewhere.

Much of the rest of the
thread seems to be about working out how to use Debian's tools
for finding and installing packages.

yes - there is much puzzlement on my part why a seemingly simple "find
the latest software offered" task is turning out to be a non-trivial
task.
Horrors.. I can't just point-n-click my way thru the [synaptics] GUI,
I need to actually read and understand the documentation.

I don't use synaptic, so I don't know how easy it is to add backports.
Joe seemed to find it trivial.

... and what has me thinking there's a bug lurking there somewhere is
me installing something from backports back in Debian 9. _without_
having to read anything other that what to put in the
/etc/apt/sources.list to say where the backports repository is and
everything Just Working.

It's always been recommended that you remove backported software when
you do your final upgrade on an older Debian version, just before you dist-upgrade to a newer version.

Cheers,
David.
