Basically my gf and i are completely oblivious to mac's. she just bought an iBook, and now we are trying to figure out the networking issue. I searched for wireless signals in the area w/ the airport card, i found a few. I found one that was BLANCA, my second guess for the password was VIVALOSMEXICO. When it says "congrats you are connected," It ends up not being able to configure the connection. What do I need to tap into this wireless signal? Can a mac only connect to mac signals?
