I have a new MacBook Pro 2011 (wanted the ports). I recently just installed an SSD and decided to enable TRIM on it. My computer restarts and I have the gray Wi-Fi symbol and "No Hardware Detected". I do everything, resetting NVRAM, SMB, all of it.
However, my Wi-Fi works when I boot into recovery mode. I have no idea why. Is there any fix for this?
EDIT: FIXED BY RE-INSTALLING Sierra
