When troubleshooting wireless, it's important that your system is fully updated by opening a terminal, CTRL+ALT+T. Using a wired internet connection, please run:
Code:

sudo apt update
sudo apt dist-upgrade

and reboot if necessary.

If the issues persist, it is recommended that you install pastebinit, by running:
Code:

sudo apt install pastebinit

This will enable the wireless script to, upon your approval, upload the obtained data to pastebin, creating at the same time a link to it in your terminal, permitting you to paste it to a forum thread.

Once that's done, download and run the wireless info script, which will gather information to help diagnose your system. You can run it using this command:
Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

It will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". If you prefer, you can post the file directly to pastebin yourself. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you aren't able to connect to the internet with the affected system, including via a wired connection, just navigate to this link and follow the instructions there on how to the run wireless script without an internet connection.

OR

I am writing a more complete answer in order to explain the exact procedure for the benefit of the inevitable searchers.

Your kernel version is 4.13.0-xx. Accordingly, we will get the driver appropriate for kernel versions 4.11 and higher. With a temporary working internet connection by ethernet, tethered or whatever means possible, open a terminal and do:

sudo apt update
sudo apt install git dkms
git clone https://github.com/smlinux/rtl8723de.git -b 4.11-up
sudo dkms add ./rtl8723de
sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414
sudo depmod -a

Reboot and your wireless should be working.

sudo apt-get install broadcom-sta-common broadcom-sta-source
sudo apt-get --reinstall bmcwl-kernel-source

I had the very same issue. This solved my problem.
