Also, make sure that your Wi-Fi router has been updated to most current firmware as well as the settings optimized for performance.

If any of the above proves to be of no help it would be a good idea to utilise your AppleCare warranty - you get three months free telephone support (3 years if you purchased the extended AppleCare) - they will hopefully be able to help you resolve the problem.
