You can't use your att connect card to use their network becuase that card is for using the cell towers. If you use that and there is cell service you will be charged 1,000s of dollars of misc. charges. If your computer has an integrated wireless card you can use that to connect to their network. Or you can buy on at like best buy or office depot. That should work because it is a network like any other network.
