I had the same thing happen to my MacBook and this may sound silly, but I re-started my modem and it started working/connecting (have Comcast).
It was wierd because my wife's and my iPad and iPhone were connected and so was every other device in the house, but my MacBook wouldn't connect. I was about to head to call Apple but I thought I'd just restart my modem and voila... it worked.
I'm not saying that it would work for you, but it did for me... go figure. Good luck, my friend.

I have the same thing happening right now, but I have to restart the modem more than 5 times a day to keep my Macbook connected to the internet. Do you have that too or did you just restarted the modem ones and it worked all fine?

I bought the MacBook Pro Retina 13" about 6 months ago. I have infinity-comcast. All my windows devices including iPhones (4 in the household) work fine but my MacBook kept disconnecting.
I called my internet provider, they came out changed the modem... same thing. I took the MacBook back to apple (thank God for AppleCare) and found out that something was wrong with the internet chip (sorry I'm not too technical here) so they replaced my MacBook with another one.
Merry XMas to me and thank you Apple. Now, the new one works fine.
