I posted something similar couple days ago on another section without much reply. Just got the Air. The wifi connection cuts in and out. Not often...probably every 10 minutes but it's annoying. We have other Apple devices such as iPhone, MacBook, and retina mini iPad all have no problems. I'm not describing safari crash some here are experiencing. I also notice when I pickup the Air to use and push the home button, the wifi symbol and bars next to top left corner of the screen is not there. It does appear after about 2 seconds. My retina mini in the other hand has the wifi bars as soon as I hit home button. Here is what I have done so far: -airplane mode on and off. -network reset -software reboot by pushing both home and power button -update to latest software iOS 7.4. This problem exist on both before and after the update. -my home router reset...I don't see why this would matter as my other devices are fine. Now! Hardware problem??? We'll I went last night and exchanged for another Air. Guess what? Yup this one has this wifi disconnecting problem as well. Those of you with air. When you stop using your iPad for a minute and hit the home button to use, do you have the wifi signals or does it take couple seconds to appear??? Anyone have any idea as to what the problem is? Should I try another Air??? Thanks!
