not only that, but the pc's in the house runing xp, vist and 7 all see the network. i have access to the modem but am really reluctant to change anything for fear of disturbing everyone else's access. i've never encountered this with my macbook pro before - i've always seen networks. i can see many of the neighbours networks too. i have included a screenshot of the modem settings. i'd love some help! also, yes i am in Brazil and password is 10 characters [6 numbers and 4 letters].

I'm going to assume at this point that since the Modem/Router is set channel 13, that this might be an early 802.11a/b/g US MBP, North America and some Central and South American countries allow only 1 through 11.
