How to find my wifi password
I have a new/old macbook and i connected to my wifi on it. but then i went away for a few weeks with it, and it had to be replaced. now i don't remember my password for the wifi. i don't know my IP either. the router doesn't have a label, it was scratched off by the previous owner.
MacBook Pro with Retina display, OS X Mavericks (10.9.3)
