Computer Issues, Grrr

My just-a-few-months-old MacBook is doing this, and it's really pissing me off. It just started doing it last week, and I was going to take it to the Genius Bar, but further research indicates that no one has had any luck with that. Mac better issue an update soon that fixes this crap! I'm sick of having to use my laptop at my desk, because it needs to be plugged in to the AC adapter to get wireless.
