Hello folks, I just bought a brand new MacBook white and so far I love it. There is one annoying issue I cant seem to fix. I constantly have to renew my DHCP lease in System Preferences as the connection keeps dropping. Either that or turn Airport off and then on. The Mac is connected to a router configured using WPA-PSK, which is hooked to a broadband connection. The issue doesnt seem to happen with my other wireless devices (iPhone, PS3...) Any clue? Thanks!
