While smart TVs are exciting appliances that allow you to play games and surf the Internet besides watching regular shows, some need the assistance of a smart TV dongle to connect to a wireless network. This tiny dongle easily connects to a USB port on your TV and acts as a LAN adapter. However, that is not all it can do. Some dongles, such as the Google Chromecast, even have their own app, which allows you to take full advantage of your Internet connectivity. Besides browsing the Internet, a dongle might allow you to stream music and videos from your mobile devices, or even use Skype. You can even transform your TV into a computer with the right dongle. For instance, the Android-powered Measy U2A allows you to use a mouse and keyboard with your TV. If just watching TV is not fun enough for you, get a smart TV dongle from eBay and widen your entertainment experience.
