I downloaded the user guide and read through it......you should download it too:

You need to launch Hub Manager and manage the hub setting of launch IE and type in "bthomehub.home" using admin for user name and password....you could manage the HUB.....there are setting in Hub Manager for wireless connectivity (on page 21 of the user guide).
hope this helps.
