Why does it say airport card not installed?
I dropped my pro a few weeks ago and it damaged my left i/o card. I have since replaced it and everyone thing is working fine until I notice that the airport icon at the top said airport card not installed. I have checked internally and it seems to be seated ok and none of the wires I can see coming form it are damaged. I have tried different ways of restarting including smc reset and holding down opt + command + r + p when turning on. I wanted to find out if there was anything else I could to check before I bought a new card.
Is this a good question?
