Well unless you call someone and have them send you a portable medium with the driver on it you need the net because it is the only easy and logical source. Do it on another machine and transfer it. I will look for the proper folder for you. Which version do you want this path for?

No, no one needs send anything. I have at least one driver for at least one of the 3 adapters even if I do not know what to do with them, and being online with the borrowed Alfa 8002.11 adapter that works then I could try one of the "sudo" this and "sudo" that suggestions. However, in 2021 why it is that Linux will not even show detection of such a basic essential piece of hardware and enable to install a driver for it by pointing Linux to a bunch of files you gathered and let it choose the right one, as the competition does? I must say I am spoiled.

Under Kubuntu I tried the below, and it connected via one of the adapters that had not worked before, though written in memory since I forgot I had removed the USB drive I was booting from. Anyway, it likely would also work for Mint if I chose to use it. For now. i may wait until the SSD comes in to install it on.
