You may have to build it from source - I had to do that for a USB 3 “AC” wifi dongle - that was maybe 3 years ago? Tried plugging it into a Ubuntu 18 machine again recently - nope - still not plug and play - have to locate the source code and build it… Don’t ask me how - sorry - I think I found the source and read the instructions (3 years ago) - pretty much gave up - I’d bought three of them - my daughters are using them on their Windows desktops fine… sometimes stuff like this also requires a rebuild of kernel objects too… PITA… Me? I’d try and find a USB wifi dongle that works out of the box…
Sorry can’t be much more help mate… someone else may have a better idea…
Firstly welcome to our friendly community. Hope you enjoy your stay with us.
Try looking in Drive Manager to add it from there. I am also pretty sure there is an article on this on the It’s Foss site, so it is worth searching there. Perhaps @abhishek remembers where it is or can help.
