what im asking iis that , the adapter would plug in and the console would be able to connect to the internet wherever you are. if this thing exists, what consoles are they for?
Yes, but it is not called WiFi. You are looking for wireless broadband such as EVDO, 3G or 4G provided by cellular carriers. This costs considerably more than WiFi (around $60/mo) and can be used with any computer that has a USB port, PCMCIA slot, ExpressCard slot or even WiFi.
This last option requires explanation. You use the WiFi in your computer to communicate with the a MiFi device (credit card sized device) that communicates over wireless broadband with your cellular provider.
There is also and internal, mini-card option for most laptops, but this would not be my recommendation for reasons of self-installation and the ability to use the other options on multiple computers.
WiFi usb adapter is a WiFi card.
NO
You need pay only for the adapter. If you have a wireless router you will not have to pay to anybody for your WiFi. But you still have to for Internet.

Wireless adapters (USB or not) are good for connecting to wireless networks (aka WLAN or WiFi).

No. A WiFi Router is not needed to use a WiFi USB adapter. You just need the internet and a compatible PC/Laptop like Windows XP / Vista. Just plug the USB in while you have the internet running and you are on WiFi.
