Fixing "RTL8822CE wireless adapter doesn't work" on Ubuntu 18.04

 RTL8822CE wifi adapter doesn't work out of the box in Ubuntu 18.04 due to missing firmware, not because the driver is not included in Ubuntu 18.04. The fix requires you to be able to download the required firmware from kernel.org and copying the firmware to your Ubuntu 18.04 firmware directory.  To do that, first, you have to make sure the machine have an internet connection before you do the steps below, either via the machine ethernet connector or some other means, in my case I have a spare USB WiFi adapter that works out of the box in Ubuntu 18.04 to do this. Then, configure the Wifi firmware like this:

sudo apt install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/rtw88/rtw8822c_wow_fw.bin /lib/firmware/rtw88 
Another approach would be to copy the file manually via USB thumbdrive, if you can't connect the connect the machine to the internet via some other means.
