Wifi not working in debian 8.9 having RTL8723de driver ([10ec:d723])
Unofficial Linux driver here: https://github.com/smlinux/rtl8723de
Please note that, I am not the author or contributor to the above driver. I came to know about this project run by user "smlinux" while subscribed to lwfinger's rtlwifi-new git project page.
I have a HP 15-BS576TX laptop with RTL8727DE wireless module and this driver worked fine. Compiling it is simple; You may either clone the source using git or download the source as zip from the above link.
Then, open a terminal in the source directory (rtl8723de) and run below commands which will install 8723de.ko kernel module to the modules directory.
make
sudo make install && sync;
sudo modprobe 8723de
That's it. After few months of owning this laptop, finally Wifi worked! Though, community must be aware that, official accommodation of this driver or other driver for this module in Linux kernel may take time. Also, please look into https://github.com/lwfinger/rtlwifi_new for any updated driver available, which is provided by Realtek, the manufacture of the said WiFi module.

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
