@andch, after searching the internet some more, I figured out that I needed to add the proposed for focal in /etc/apt/sources.list in order to install the kernel 5.14.0-1035.38 (the same one that you installed). So I did all that, and THE FIX WORKS. My smartphone can connect to the hotspot and access the internet.
