I was so disappointed when my Pi lost wifi after the November or December 2019 OSMC update. They have dropped support for the dongle I've been using for several years, apparently due to poor support from the manufacturer. One of the reviews here said it would work so I added it to the order to put it on free shipping. Connected it to the Pi and it worked right after turning it on. So if that bothers you, this will fix it.
