From where does the stick pick up the wifi? Do I have to provide wifi and if so how?
I don't understand wifi. is it from a device you buy to subscribe to wifi or is it a broadcast signal without need of add on receivers?
You do need to have wifi. If you have Internet you probably have wifi. It's just wireless internet.
The stickies great.
It plugs into you TV in an USB port. If your TV does not have a USB port you can probably get an adapter. Take a picture of the back of your TV and bring it to best buy. If you don't have a USB port on your TV they can help you get the right adapter.
So the stick is great. It connects your TV to the Internet. It has some apps built in, netflix, Amazon and others. You can easily add others like Redbox. You just set up an account online then login to your account via the stick. The remote that comes with the stick makes navigation easy.
