In order to make my wireless internet network secure, I added a password to it today. Every other computer in the house, as well as my XBox 360, is able to connect to the internet using the password that I set up. For some reason, when I try to connect to my Macbook, it tells me that the password is wrong, yet it works with the other 3 computers in my house. What am I missing? Do I need to change my settings on Airport? My wireless router is obviously working so what do I need to do? Thanks!
