Apple has officially acknowledged that the latest product MacBook Air has a serious structural defects.
The manufacturer advises that when the closed notebook is connected an external monitor is rapidly declining coverage and transfer-in Wi-Fi in the 2.4 GHz band. The same problem occurs when your computer is working simultaneously with multiple devices. Most likely the problem is due to too low intensity of the current supplied to the Wi-Fi system in the above-mentioned situations.
Another problem is the Remote Disc software included in the MacBook Air. The idea is to allow it to remotely “sharing” optical drives of other computers running the Apple operating system Mac OS or Microsoft Windows. As it turns out a variety of wireless routers do not allow the use of such a possibility. Apparently sometimes helps to update the firmware on the router.

This means that if necessary, read the disc (eg installation of another operating system) computer user will have to connect an optical drive via USB. It is worth mentioning that the MacBook Air has only one such slot. As it turns out Microsoft Windows in general can not be installed via Remote Disc, it is necessary to purchase an external drive. Otherwise, the application Boot Camp (for installing other systems on the Mac) will not work correctly.
