I have Cricket Wireless internet, but since the Wireless modem has to hook up directly to the computer, I have to use my Computer as the router.
Here’s where I encounter the problem. When I run the tests, the XBOX detects the computer, and confirms the IP Address, but when it hits the DNS test, it fails. Is there something Special I can do to use my computer as the router?

I have the Cricket USB modem and it is currently plugged into my desktop computer. But can I plug the USB modem into a wireless to share the connection with my laptop and PS3? If not, is there any way to share the connection of the USB Modem?
