Extremely easy

Meu Problema

The WiFi card stop working. I tried several software solutions (reboots, restarting of obscure management services) until I realised it was a hardware issue. Since the MacBook Air 11" Mid 2011 is considered obsolete by Apple, I couldn't get official support

Minha Solução

It was very easy to follow the steps in the guide. I had no problem and did everything quick with the tools I bought from iFixit (a bit expensive, considering delivery and customs costs).

Meu Conselho

I was afraid the WiFi card I bought (from iFixit) wouldn't be good quality, since it is not an official replacement. It is a bit more expensive than those you can find on eBay, so I was hoping iFixit would deliver a good quality piece of hardware. It works fine so far.
