So I need a basic (and budget) card to connect my computer via wifi in case an ethernet cable isn't available. I'm not sure what specs you need, but I have a linksys router. Sorry, I know nothing about this, but if someone could help me I'd really appreciate it. Preferably nothing higher than $50. I won't need blazing fast connection speeds, and I won't be farther away than a single wall/room, and about 50 feet.
