Resolved WI-FI missing after SSD installation

[danielekan]

Hello, I just put a Crucial SSD in the optical drive spot of my late 2009 iMac 21.5".
I booted from usb and installed Sierra in the new hard disk.

But I must have forgot (or damaged) WI-FI hardware, because no WI-FI is showing up neither in the new OS, nor in the old.

Any ideas what could it be?

Thank you

Never mind, stupid question. I had somehow disconnected the airport card. Now it's fixed.
