Recently I had to set my computer back to factory default thinking that it would go back to the way it was when I got it. However, when I did the wifi never lit up and everytime I try to connect to the internet to my router it says it can't connect because of some switch or code that needs to be pushed or entered. Well, I looked and there's no switch and I have no idea what code it needs. It wasn't like this when I got it and I really need to get back on my other computer.
