Buffering is caused by the internet connection between your router and your device cutting off and joining again, so to play a programme smoothly and without interruption, you’ll need a good internet connection.
However, if your internet connection isn’t fast enough you’ll see a message saying you have ‘insufficient bandwidth’ (bandwidth is the amount of data your connection can transfer). This could be because you’re either sharing bandwidth with other devices or you are connecting to your internet router via WiFi and the signal quality is poor.
If you're having issues with your internet connection, please contact your internet service provider, especially if channels and programmes from other broadcasters are affected.
Sorry about that. Please take a second to tell us what's wrong with it.
