So I just installed Ubuntu 18.04 desktop alongside Windows 10. But despite the fact that the password I typed is correct, I still get prompted by this message.

sudo nano /etc/modprobe.d/rtl8723de.conf

Copy and past this line and save and exit:

options rtl8723de fwlps=0

Reboot.

This should prevent the WiFi card from automatically sleeping and halting connection.
