How to install Wi-Fi drivers in Ubuntu 16.04?
lspci -v | grep -i network 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device d723
You may use the driver hosted at Larry Finger's
rtlwifi_new git repository. Make sure you have
linux-headers for the respective kernel(s) and
build-essential package installed. Then follow the steps below.
dkms if they're not installed by running
sudo apt install git dkms
Clone the repository
git clone -b extended --single-branch https://github.com/lwfinger/rtlwifi_new.git
Run the following commands to install
sudo dkms add rtlwifi_new sudo dkms install rtlwifi-new/0.6
This should also work with newer kernels (and hence on Ubuntu 18.04 too).
Note: If you get very weak signal try changing your antenna selection
sudo tee /etc/modprobe.d/rtl8723de.conf <<< "options rtl8723de ant_sel=2"
ant_sel=1 if 2 doesn't help).

There is new information on this device! With a temporary working internet connection, open a terminal and do:
sudo apt update sudo apt install build-essential dkms git git clone https://github.com/jeremyb31/rtl8723de.git sudo dkms add ./rtl8723de sudo dkms build rtl8723de/18.104.22.168_21285.20171026_COEX20170111-1414 sudo dkms install rtl8723de/22.214.171.124_21285.20171026_COEX20170111-1414
Reboot and let us hear your report.
This won't work for Ubuntu 18.04 because of the new kernel incompatibility.
