I have recently bought a nintendo wifi usb connector because i dont have wireless internet. I tested it out and it doesnt work it says it cannot connect to the internet.

Is there something wrong with the shared connection between my modem and the usb connector or is it something else. I have a linksys am300 wired modem. plz help i'm over my head with trying to fix this.
