Hello, I havve a iMac 27" Mid 2011 with this absolute awesome feature of losing WiFi Connection every blink of an eye. Not that my StatusBar or so would indicate it! No, its just gone. Safari won't let me go to any page, no other Program gets a connection.. etc. The only Fix right now is, to deactivate and reactive the WiFi on the bar, and hope that it won't lose connection again in 10 seconds. Which in most of the time it does. Same Problem happens to me if I open Windows in Bootcamp. Is this the fault of the WiFi Card and I should go to the local Apple Store to tell them nicely what my concern is - or is there anything else I can do?
