Query: Enter the world of WiFi

Plug this device into your laptop and you will have Internet access for thousands of WiFi hotspots all over the world. Some you have to pay for, but increasingly hotels and cities are making them available for free.In addition, you can make your home completely wireless by installing a wireless router and wireless print servers.All of the parts worked perfectly for me with no installation hassles whatsoever. This is absolutely the way to go.
