My friend Jenny lives in an apt complex with public wifi access. They have NO access to the router or any ethernet jack, and must provide the front desk with their MAC Address to let their laptops connect to the network. How can we get her MacBook Pro and Time Capsule talking via wifi in this configuration? I'm not sure the TC will be able to join this network. Right now she is at home, and I am testing this config by simply shutting off her wifi connection at her house to see if the TC and MBP can talk with eachother alone...that hasn't worked at all.
