Ever since I got my 2013 MacBook Air 13" upgraded to Intel Core i7, I'm experiencing issues with the internet. It keeps disconnecting for no reason. This never happened on my previous 2012 MacBook Pro 13". First I though there is something wrong with the wi-fi routers. I contacted Comcast dozens of times, they just sent out refresh signals, until they decided to come and replace the routers. Then when the problem kept occurring, they told me that there must be something wrong with the laptop. That's when I contacted AppleCare, I sent it in for a repair. After I got my laptop back, yes, the problem still happened. I contacted AppleCare back, and I had to send it in for a repair again. When I got it back, guess what, the internet still disconnected. So when I called back, they transferred me to a senior supervisor which told me that we will need to do some diagnostics. We did the diagnostics for hours at times over the phone. I sent him diagnostics file when the internet was working and when it was now. When I told them every other Wi-Fi device works fine in my house, and asked if they could replace the laptop since it never happened to my other MacBook and non of my other devices disconnect from the internet. They refused, they said that's not an option. What should I do? What would you do?
