If you are having difficulty accessing wireless through WUFI you can instead go through WUFI-S. There are a couple steps to set this up, but it should work even when WUFI doesn't (provided wireless isn't actually down at the time).

To configure your laptop for the wireless network (WUFI-S), please follow the instructions specific for your operating system listed below:

Mac OS 10.3 (Panther) & 10.4 (Tiger)

Mac OS 10.5 (Leopard)

Windows XP

Windows Vista
