AC1200 Wireless adapter in Ubuntu 19.10

I did the following in a terminal to get a AC1200 Linksys Wireless adapter to work on my Ubuntu 19.10 install:

sudo apt-get install linux-headers-$(uname -r) linux-headers-generic build-essential git
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux
cd rtl8812AU_8821AU_linux
make
sudo make install

This process went through without errors and install was completed. However, my wireless USB adapter still doesn't work. I ran lsusb in terminal and my wireless adapter was listed as

Bus 002 Device 004: ID 13b1:003f Linksys WUSB6300 802.11a/b/g/n/ac Wireless Adapter [Realtek RTL8812AU]

I then ran the following, and it simply returned the command line prompt

modinfo 8812au | egrep -i 'versi|filen|003f'
sudo modprobe -v 8812au
iwconfig
iwlist chan

When I opened my network setting for WiFi, I received the following:

No WiFi Adapter found
Make sure you have a wifi adapter plugged in and turned on

I also tried to get it to work by installing ndiswrapper, but that didn't work either. I have researched this and have tried numerous things I found, but nothing seems to work. I know this has been answered before, but the answers all indicate the above procedure. Any help is appreciated as I am new to Ubuntu, but have run Red Hat linux prior to its shifting to Fedora.
