Has anyone found a solution or specific cause of this? I had a 2011 MacBook Pro I bougt back in February when they were released and it constantly disconnected from my home wifi network about every 5-10 min...so annoying! Since I've had an iMac and now a 13" Air that work perfect without issue on the same network as well as all my iOS devices. I just bought another MBP to replace the Air...brand new and it's doing the same exact thing. Constantly dropping off the network. Adium goes up and down constantly...browsers start timing out..lose my SSH connections constantly. How in the hell has this never been resolved? Any insight/advice/news would be appreciated. I need the MacBook Pro but this is making me want to figure out how to keep and use the Air it's so damn bad.
