#64598 — Bug#933302: firmware-realtek: RTL8723DE not working

Package: firmware-realtek
Version: 20190114-1
Severity: important

Dear Maintainer,

on a fresh Debian 10 installation on an HP 15-bw061nl, despite having installed firmware-realtek, the wifi card does not work.
(I have set up the laptop as dual boot and the card works in Windows 10)

Strangely, I do not seem to have the rtl8723de kernel module since modprobing it returns

  modprobe: FATAL: Module rtl8723de not found in directory /lib/modules/4.19.0-5-amd64

Is it named something else? In addition to installing the firmware package, do I need to install something else to get the card working?

Thanks!

Matteo

#66741 — Bug#933302: RTL8723DE not working

Hi,

I just attempted to help a user in OFTC #debian with this nic and
confirmed/discovered the following:

- there is no rtl8723de module in buster or bullseye/sid's kernel,
despite the binary blob being present in firmware-realtek
- Ubuntu's 5.4 kernel *does* have support, but it's via the RTW88
driver that should be unrelated aiui because the 8723DE nic is 802.11n
and RTW88 is specifically 802.11ac, and yet:

jesse@bivouac:~/temp/ubuntu$ grep -i rtw88 boot/config-5.4.0-21-generic
CONFIG_RTW88=m
CONFIG_RTW88_CORE=m
CONFIG_RTW88_PCI=m
CONFIG_RTW88_8822BE=y
CONFIG_RTW88_8822CE=y
CONFIG_RTW88_8723DE=y ****

The user in #debian confirmed that the ubuntu driver supported their nic.

Bullseye's 5.4 and sid's 5.5 have RTW88 as well, but sans 8723DE. See
https://salsa.debian.org/kernel-team/linux/-/blob/6ba1f0beb871cf2ba9a12837cf51999692a08c53/debian/config/config
for 5.5.

Hopefully this information helps get support for the rtl8723de into bullseye.

I'm afraid that option doesn't exist in the upstream Linux version of
rtw88 (not even in 5.7-rc1).  Until it is added, we can't enable it in
Debian.
