I have set Wi-Fi in my room because my kindle needed Wi-Fi connection to transfer data.
I only bought a wireless router because I've already contracted an internet provider. The setting up of the wireless router was very easy. It only took me 20 minutes to set it up. And I finished transferring data from old kindle to new one without accident.
Other gadgets with Wi-Fi also use the network. My internet connection became a very useful tool in my room.
