mnsps, you do have to use the serial cable intially to do all the settings. but i have the EXACT same problem as you. i tried for a week and gave up and still have not hooked it up. i would do all the setting with the serial cable hooked up and when i would disconnect it and try to connect it was lost. a couple pages back big blue posted his way of connecting to wlan, you could try that and see if it helps
