You have a few instances where a dkms module was added, but not fully installed.

sudo dkms remove rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414 --all

If there are any errors after any of these commands, STOP and post them here. Do not proceed until these errors are fixed.

If there are no errors, then do:

sudo rm -rf rtl8723de
git clone -b 4.10-down https://github.com/jeremyb31/rtl8723de.git
sudo dkms add ./rtl8723de
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

Then reboot.

Again, if there is any error, stop and tell us so we can fix it first.
