You just need the LIVE! addition to your Dashboard.
Do the following:
SETTINGS -> NETWORK SETTINGS -> ADVANCED -> WIRELESS -> SETTINGS -> NETWORK NAME
It will do the stupid Live! loding circle thing, which is so ghey, and then come to a screen that says 'SELECT NETWORK', and which time... select your network.
It will do the stupid circle thing, again, and then it should go to the Wireless Status page, at which you should be go to go.
