@ipswich if other apps run properly its unlikely to be a wifi speed issue. If you have a Netflix app run the network test in that app's get help menu.
If you need better wifi to stream video then you either need to psy Sky yo get their WiFi Max bundle which can supply up yo 3 extenders or buy your own wifi kit.
