Hi Kathy,
I found this answer
sudo apt install git dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo ./dkms-install.sh
that worked for me at
With the default Tegra-Nano disk image “sd-blob-b01.img” and using the above commands I was about to build and install the drive. Through the GUI I joined my phone hotspot and download some GitHub webpages. Range is limited and I have not tested throughput nor stability.
I hope this works for you.
Regards
Kelly
