@Tatts56 video streaming requires both sufficent bzndwidth and a regular signal not affected by interference as a marginal WiFi signal will cause buffering. You can often improve the WiFi signal by making sure both the device and the hub are out in the open and not onnthe floor, so, for example, having the Fire Cube hidden behind your TV.
Failing thst you may need additional kitvto improvecthe WiFi which will cost money either to pay Sky for one of their add-on packages like WiFi Max which includes WiFi extenders where required orvto buy your own third party kit.
