Since buying my MacBook Air (MBA) I have loved it except for the wifi which kept hanging as the system searches for new connections even when connected. The solution is to buy a bearextender n3 - - I suggest googling that and reading the reviews. Since buying one my wifi connection has been continuos, reliable and so much faster. It cost $50 plus shipping but is worth every cent for the extra usability it brings. Apparently it was designed to find connections one can't find without, but for I use it to get a much better connection to my home wifi. It's a shame to have to buy something to do what the MBA should do out of the box, but there you go.
