I am noticing a strange behavior with my new 17" 2011 macbook pro 2.2 i7: The wifi connection drops out - I mean I'm connected to an access point (wireless N) - but after a while when I don't use the laptop (letting it idle), I come back and the wireless connection is gone. I have to turn airport OFF then back ON to resume the connection. Once it actually "lost" my access point password as well. I don't have the computer sleep automatically (turned off in power savings preference) nor do I have the laptop shut off hard disk whenever it can. I'm having a feeling though when the LCD screen goes into sleep it turns off my wifi but I tried setting the LCD to shut off every minute but connection still remains..it's only when I come back after 15-20 minutes do I see this occur. Anyone else have this issue? Alright, I tested it this time again - I left the machine ON overnight. I come back now and voila, the wifi connection is GONE! IN fact, when I click the airport icon, it shows NO NETWORK DETECTED. I have to turn airport OFF then back ON for a connection to become active again. This is definitely an issue - anyone experience the same thing?
