    @RuiFRibeiro the rtl8723de driver is recently provided to linux system. – GAD3R May 6 '18 at 12:30

    @GAD3R Despite added or not added, they are all problematic. – Rui F Ribeiro May 6 '18 at 12:31
  • I recently found out that WiFi adapters are worse than video cards after mine stopped working after a couple of years when the firmware got removed from Ubuntu. If you don't find a solution quickly, you might want to return the notebook. USB WiFi adapters supposedly work, but the two I've tried so far don't. wikidevi.com/wiki/Category:Linux_driver/802dot11 may prove helpful. – Joe May 11 '18 at 23:30

Following this worked for me in Ubuntu 18.04

Clone this repository:

git clone https://github.com/lwfinger/rtlwifi_new.git

Enter the cloned folder:

cd rtlwifi_new

Checkout the extended branch:

git checkout extended

Start installation:

sudo make install
sudo modprobe -r rtl8723de
sudo modprobe rtl8723de
