User: Hi, I'm having trouble connecting to my wireless network. It's been working fine for weeks but today I can't connect.
Me: OK, exactly what error message do you get, or what happens when you try to connect to the network?
User: It says I am not authorized to access the network. It keeps saying something about a WPA Key. Do you know what that is?
Me: Yes, that's a security password that is set up on your wireless router. You need to input that security password. Do you know how to access the administration page for your router?
User: Well, it's not really MY router, it's my neighbor's... I've just been using the connection. Is there any way to get around this?
