Over the last few days we've been hearing from several of our readers about WiFi instability on new Haswell-equipped MacBook Airs, which also happen to be Apple's first computers with 802.11ac. Despite those rare reports, the company's new laptops impressed us in our recent review with solid performance and incredible battery life. Today 9to5Mac learned that Apple is supposedly aware of the issue and working on a fix, while some customers have also reported getting their systems replaced. In the meantime, the company's apparently directed its Genius Bar employees to "capture" machines experiencing the problem -- i.e. return them to Cupertino for testing. We've contacted Apple for comment and will keep you posted if there's any official response.
