If you just need internet when you're at home or at work/school where a wireless (WiFI) accesspoint is provided you wont need this usb adaptor.
If your current router at home (assuming you already have a normal pc connected to the internet) doesn't have wireless functionality yet all you need is a wireless router or a simple accespoint.
- If you already have some kind of wireless accespoint device at home you can connect to that with your laptop and you wont have to buy anything.
- If you already have a router at home, but it doesn't have a wireless (accesspoint) function you'll just need to buy an accesspoint which you can connect to the router
- If you don't have any router yet but just a modem where you can only connect a single PC to, get a router with wireless functionality (accesspoint) build in.
- If you want to be able to use internet everywhere (while traveling and not in reach of a public accesspoint) you will indeed need something like you linked to in your post. But keep in mind internet over mobile connections is still relatively slow and expensive.
