Did you go thru and check your account settings in the Wiz, there is an option to check? If that fails, then did you setup your IP correctly, did you do DHCP (which normally gets all the correct parameters, and you usually don't have to do anything else) or did you put in IP addresses manually? If the second, can you ping it from a PC on the same network? If you can do that, but the ICE check fails, then it is probably either your gateway or DNS settings are not setup correctly.
