I'm looking at these two adapters for my computer that is not wireless at the moment and was wondering which would be the better buy.

There isn't any room for a card so I'm stuck going the usb route and trying to find something that will work good

I bought this one for my parents

They uses it on their desktop and it works just fine. It found their wireless router immediately and setup was a breeze.
