Smart TV VPN - http://www.identityvoucher.co.uk
A VPN is extremely useful for your home network. Not only does it secure your internet connection but you can also use it to hide your IP address and access content which is normally blocked.
Unfortunately most network enabled devices like Smart TVs, phones and media streamers like the Roku won't let you change network settings let alone install a VPN client.
This short video shows you how to install a VPN that all your devices can use on your router. It's quick and simple but requires a compatible router/access point and a VPN subscription.
