Hmm what card is this? Sadly not all work. Also do check out if there are linux drivers from the manufactor website... It's confusing, yet it seems like it's already been like setup but just incorrectly, it wants you to almost delete and reinstall properly... Also just for the hell of it maybe you want to upgrade from 6.1 to like 7.0 or even 8.0, it's just works a bit better. I'll try to look into it when I'm not falling sleep or needing more energy drinks.
