Your USB data card can receive signal wirelessly but cannot transmit WiFi signals. You can try the following1. Buy a router which supports 3G data card. 2. Get a USB WiFi dongle and use some application that can create a WiFi hotspot.3. Get PCI WiFi card and use an application which can create WiFi hotspot.They options are cheaper as they come down the order. I think you will need Windows 7 to use a software which can make your PC a WiFi hotspot.
