FYI: You are using a EOL kernel, a fully upgraded Ubuntu 18.04 system should be using the 5.4 kernel (as 5.3 is EOL). Have you not upgraded via ethernet? or are you using something other than Ubuntu 18.04 LTS (as 5.3 is unsupported)– guivercAug 16, 2020 at 10:38

I have had problems getting WiFi to work with countless laptops and versions of Ubuntu down the years.
After much time wasted trying to fix this I eventually bought one of these:
https://www.amazon.co.uk/TP-Link-TL-WN823N-Wireless-Supports-10-9-10-13/dp/B0088TKTY2
I have never looked back.
First, check your kernel version with uname -r
, then
sudo apt install linux-headers git build-essential wget unzip dkms
(linux-headers of installed kernel version, you may use synaptic package manager)wget -d -c -O 'rtl8723de.zip' https://github.com/smlinux/rtl8723de/archive/4.11-up.zip
to download the driver zip file for kernel version 4.11 and upunzip rtl8723de.zip
shall unzip the driver foldercd rtl8723de
will take you to the respective directorymake && sudo make install
shall install the driversudo reboot
P.S. If you're using kernel version 4.10 or down then wget -d -c -O 'rtl8723de.zip' https://github.com/smlinux/rtl8723de/archive/4.10-down.zip
shall give you the driver file
Hope it helps
