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!
