Little bit more precise would be helpfull. But I can guess that DEVS means that you should put prism2.device to it, wich is device driver for you wlan card.
192.168.X.X is can mean several things, your IP address, or default gateway IP address, it even can be IP address of you DNS server. But Roadshow has a working DHCP clien, you should enable it, to me sems that you haven't done that?
