Wifi sync issues still occur with Airport Extreme Base Station. Funny that the iPad and MBP connect better to the MWEB Technicolor network than the one set up by the Airport Extreme. Apple products are simply not that compatible with each other, it's better to always get from compatible vendors.
I wonder when we can be expecting a patch for wifi issues. New to Apple culture, it somewhat irks me to have sync trouble after buying a premium product. It seems that this will become a benchmark test for patience and not device performance.
