I'm on my 2nd MBA 2013 replacement from Best Buy and *still* have WiFi issues and am debating on either getting a 3rd replacement or just getting a refund. I don't even know if Best Buy would be willing to make an exchange for a 3rd time, but the way things are looking I feel like just getting a refund and wait until Apple decides to get their **** together. I do need a computer for schoolwork but I could probably manage for a couple months without one if it must come to that. What should I do? I wonder what percent of 2013 MBA's even have functional WiFi straight out the box
