Q: MacBook Unibody Model A1278 Wifi won't turn on.

Hardware not recognized. Rest PRAM, SMC, reseated all connections, disabled and re-enabled the connection, all to no avail. Can't get Diagnostics to startup to verify if the card is bad before buying a new one if needed. Anyone know of another way to start Diagnostics other than Option D or D at startup? Or another way I can try and fix the wireless or verify if the card is bad?

 

Thanks, JD

MacBook, OS X El Capitan (10.11.5)
