The package firmware-realtek is indeed in non-free. And yes, the installer does include non-free firmware.

See also this discussion back from 2018:

Regarding your actual issue: I think as well that the driver may not be in 4.19. Please try the backport kernel and report back.

I think your wifi is never than the 4.19 kernel. So it is not supported by that. You can try the following http://ubuntuhandbook.org/index.php/201 … ntu-19-04/ or install a never kernel from backports.

Have a nice day

The modprobe command loads kernel modules rather than firmware.

Can we see the output of

# dmesg | grep firmware

I don't think installer have non-free packages, he was not able to recognize my wifi.

Thank you for answering, Tatwi, but the point of my trouble is that "firmware-realtek" is already installed by me, and did not do anything, sadly.

You may need to add the non-free tag to /etc/apt/sources.list file, update the cache, and download the firmware package. Not sure why the installer wouldn't install itself from the CD/DVD/USB (it did with my laptop with intel wifi, which is good because it doesn't have Ethernet). If you can't get online, you may be able to mount the installation media and manually install the package in the firmware directory using dpkg.

/etc/apt/sources.list:
deb http://deb.devuan.org/merged beowulf main non-free contrib
deb-src http://deb.devuan.org/merged beowulf main non-free contrib

apt install firmware-realtek

lspci says:
"Realtek Semiconductor Co., Ltd. Device d723"
So it's rtl8723de, which I found in the "firmware-realtek" package:
"apt-file find rtl8723defw.bin
firmware-realtek: /lib/firmware/rtlwifi/rtl8723defw.bin"

Installed, rebooted and nothing happens. Modprobe says that this is no module "rtl8723de" in lib/modules/4.19.0-9-amd64

Please explain what am I doint wrong? Do I need to install it from https://github.com/lwfinger/rtlwifi_new/tree/extended?
