This tutorial is a rewritten of the previous ‘Fix ‘No WiFi Adapter Found’ for HP Laptops with Ubuntu 18.04‘, since wireless will stop working after installed or upgraded to a new Linux Kernel.
Following steps will install the newest Realtek rtlwifi codes including rtl8192ce, rtl8192cu, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, rtl8821ae, rtl8822be and rtl8723de in Ubuntu with DKMS (Dynamic Kernel Module Support) support. So it will work in each kernel on your system.
This may not work if you already installed the drivers and broke things up. I would recommend to do the steps in a clean install of Ubuntu desktop.
1. Connect your laptop to a wired network, and then open terminal from application menu.

2. Run command to install some required tools:
However, today I downloaded the Linux Mint 18 Beta (64 bit Cinnamon) and installed it on a brand new out of the box Dell Latitude ES470 and I cant seem to get the wifi to work. I think it may be a drivers issue. Sometimes, the Additional Drivers Utility will fail to install a Broadcom STA Wireless Driver. When that happens, first check if your card is indeed supported by the STA driver, and to do that, open a terminal window (ctrl-alt-t) and run.
Type user password (no asterisk feedback due to security reason) when it prompts and hit Enter.
3. Now grab the rtlwifi_new codes via command:

4. Add the source to the tree for builds with DKMS support.
5. Finally install the drivers via command:
6. If everything works OK, Wifi should work immediately (it works in my case in Ubuntu 19.04).
If not, try commands to load the new installed module (rtl8723de in the case):
Install Wifi Drivers Linux Kali
7. And Wifi works after reboot without doing any configuration, at least in my case in Ubuntu 19.04.
Kali Linux Wifi Setup
If not, try command to write it into configuration file (replace 3 to 1, 2 or 4 if signal is weak).
Install Wifi Driver Linux Mint 19
In addition, if you happened to update your system with newest Kernel packages without reboot. You need to reinstall the kernel packages to get the module work after reboot.
