Terrific guide; no problems, at all! Don't forget you need to add the Wi-Fi service back to the list of services:

1. Go to System Preferences → Network and click the + button to add a service.

2. Select Wi-Fi as the Interface and provide a service name.

At Step 11 I accidently pulled the connector off the board incorrectly and it won't fit back on. What is the difficulty level of resoldering this back onto the logic board or should I take it to a professional?
