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.
