I have had Animal Crossing Wild World for a very long while now and I really felt like to play with someone over wifi. I do have the internet, and I'm willing to play with some people, after I get this issue out the way. The issue is that I have tried to get a friend code but it can't find my internet. It then keeps saying that I have to register my WEP key. What if you don't have a WEP key? I don't understand what it is? Could someone please help??
