Thanks for including so much information :slight_smile:

I ran this card a while back on one of the 4* Kernels.

The current driver for Linux Kernel 5+ is smlinux.

Install instructions from the page:

git clone GitHub - smlinux/rtl8723de: Realtek RTL8723DE module for Linux -b current
dkms add ./rtl8723de
dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
depmod -a
reboot

You can find the driver here:

Hey, thanks for the driver, installed it and it works great but one issue occurred, whenever I tried to switch wifi it disconnects again and never make connection, I have to reboot to change the wifi connection.

Try an earlier kernel for better compatibility. You can do this through Synaptic or commandline by first searching:

apt search linux-image

As of this reply, there are many open issues including a kernel update ‘breaking’ compatibility: https://github.com/smlinux/rtl8723de/issues/75

This driver came out as a fix for problems with previous driver not working in kernel 5. Try an earlier version of the Linux Kernel 5.

Thanks @RightToPrivacy, it works by downgrading the kernel-version.
