    Hey Guys,
    First time posting a question on macrumors so sorry if I'm in the wrong place!
    I recently change the disk drive for a HDD on my 2012 13" MBP and then the wifi stopped worked (says "No Hardware Installed". The bluetooth still works fine though.

    I need to fix this and I know its not a software solution so before I go spending all my £££ how can I tell if it's the cable or the card itself thats broken?

    Thanks in advance!

    Short of replacing both parts one at a time it's pretty much impossible, unless you can see some damage to either one which indicates which it could be.

    Do you mean you fitted an additional HDD with an adapter in the optical bay? If so you have to disconnect elements of the WiFi so first thing to check is that you refitted the WiFi components and all the related screws etc from that work.

    Logically if you've put the same Airport card back in the issue would be with the cabling - you may have not connected one of the three.

    I would be interested in what you find though so do post back.
