Nový MacBook Air although it supports the IEEE 802.11ac standard, despite this enormous speed, this new device is not able to use the full speed of the new wireless standard. As discovered by the foreign server ArsTechnica, Apple apparently nestihol has fully adapted OS X Mountain Lion for 802.11ac, which greatly limits the system maximal connection speed to the wireless network.
As it turned out, the error is not in the hardware, but in the software. The ArsTechnica server decided to test the new one MacBook Air with two different operating systems on which he recorded different data transfer rates. In the first case, when the server decided to use the AFP protocol or Apple Filling Protocol, achieved a new MacBook Air maximal speed of 100,72MB/s. In the second case, it was already the SMB (Server Message Block) protocol, a new one was reached Air but much less speed, only 67,52MB/s. The device used the OS X 10.8.4 operating system, which Apple published shortly before the conference WWDC.
The speed he recorded at MacBookus 64-bit version Windows 8, was visibly higher in both cases. Because however Windows 8 via Boot Camp only supports the Server Message Block protocol, the portal was able to test data transfer only in this way. Maximal speed achieved by ArsTechnica when transferring data over Windows 8 64-bit, represents 110,70MB/s, i.e. a speed that is up to 10.8.4MB/s higher, or 43,18%, compared to OS X 39.
However, it is still certain that this is a software bug and Apple he will be able to fix it in the form of an update that he can release in the coming weeks.

and with the loss of wifi, what does it look like?
I bought that computer because I wanted something that would be, unlike ultrabooks, work..
But it doesn't work.
after last year, the wifi error is already a traditional matter since applol, if wifi doesn't work, at least 3G and the like
it will be fixed
in 10.9, it switches to smb2 at any speed, so the problem is already being worked on
