Before you moan, It's my work Laptop, it's a mac.
I had the airport replaced by the Apple store in Chicago,
Now however, when I connect to WiFi i get connectivity for all of 1 min then it dies. i.e. I'm on the Wifi but no internet
Upon further inspection my device is seeing 2 airport cards, with diff Ip addresses.
if I turn off one, both turn off. Any advice?
