you need to install linix headers generic by:
sudo apt-get update
sudo apt-get install linux-generic
I see you already have downloaded the realtek wifi drivers make sure you are in the right directory and run this to install them:
cd rtlwifi_new
sudo dkms add ../rtlwifi_new
sudo dkms build rtlwifi-new/0.6
sudo dkms install rtlwifi-new/0.6
sudo modprobe -v rtl8723de ant_sel=2
Congrats you have running wifi.
Save the config with this command:
sudo /bin/sh -c 'echo "options rtl8723de ant_sel=2" >> /etc/modprobe.d/rtl8723de.conf'
Restart.
