I just got the new 2013 MBA 13.3" last month. It is almost identical to my late 2011 MBA, so there is apparently no learning curve and nothing new to expect. However, the very first thing I noticed was that the wifi kept dropping the signal, like every 5 minutes. This is a right-out-of-the-box issue. I did an online search, and it turns out to be a known flaw that was SUPPOSED to have been fixed by OS upgrade 1.0 which I downloaded and installed. The Apple patch did nothing, so I took it in for servicing and Apple Tech replaced the wifi card. Problem solved? NO.
There is some improvement, in that I do not have to restart my computer each time the wifi loses signal, as was required before. Now when the wifi loses signaI, I only have to turn wifi off and on again before it reconnects. But that is not enough improvement for me. It seems like Apple has a more fundamental flaw in the architecture that continues to make this issue recur, even after a new wifi card is installed. Does anyone have insight into this issue as of this current date? The purported "fix" happend over a month ago.
Thanks for any and all information that may help to correct this problem
