@S+mulvey asunming you are talking about streaming video from the internet? If you are run the serviceccheckercinntge My Sky app which will show thecspeed to your hub. If that is low the appmor Sky should help. If the speed to your hub is OK the most likely cause is poor wifi as streming video requires good wifi. Poor WiFi coverage is probably the most common question we get in the forum. In many homes a single Sky hub cannot provide a usable wifi signal in every room due to the layout and type of construction of the property especially in older homes. Assuming the hub is in the best possible position which is out in the open on a surfsce then the only answer is additional wifi sources.
Your choice.is to either buy Sky's add-on WiFi Max bundle which can supply up to 3 extenders see https://www.sky.com/help/articles/sky-wifi-max or buy your own wifi system and use that instead of the Sky hub's WiFi.
Of course if you use Freeview or Satellite to watch TV then the aerial or the dish on your home are the likely causes.
