Had the most strange errors with a wi-fi with errors for long. Send the computer both to apple and to insurance without success.

Now I'm on my own on my wifi first broke saying "No hardware installed", Bluetooth was still working in the beginning thou. After checking here I ordered a new cable and everything was fixed in under 30 minutes.

The cable I bought was names -A in the end instead of -02 but everything works just fine so far. According to the seller they are the same. Thanks for help solving this strange problem in a simple way!

Fixed my wifi connectivity problems! However it did not fix my bluetooth connection. I did have a problem where the wire was actually disconnected from the actual connection and the connection was stuck in the socket. I got the connection out by using an Xacto blade on the side to pry it out. Then I followed all the other steps and it worked fine! I also disconnected the battery and had no problems reconnecting it.
