Wi-Fi only works in Recovery Mode 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
You may need to add the Wi-Fi service:


Open System Preferences → Network and choose + to add a service.
Choose Interface: Wi-Fi and Create.
