Practical checks for slow or interrupted playback. These steps are designed to help you troubleshoot or compare options using your own compatible device and an authorised viewing service.
Step-by-step checks for home broadband, Wi-Fi, apps and playback quality. The steps below are written for people using a typical UK home connection, with no specialist equipment or advanced technical knowledge assumed.
First identify what is failing
Try more than one video or app. If every online service stalls, the home connection or device is a likely place to start. If only one app fails, investigate that app and provider.
Make a note of whether the picture freezes, the audio continues, or the video quality drops. Different symptoms can point to different causes.
Check Wi-Fi where you watch
Run a connection test near the television, not only beside the router. Move the router away from obstacles where possible and reduce interference from nearby electronics.
If available, try a wired ethernet connection or move the device closer to the access point to compare performance.
Restart and update
Restart the router, playback device and streaming application in an orderly way. Check for current device and app software updates.
A full restart can clear temporary problems, but recurrent buffering may signal a more consistent connection or service issue.
Reduce network pressure
Pause large downloads or cloud backups while watching. If your router supports device prioritisation, consider whether the television needs a more stable share of available bandwidth.
Avoid changing advanced settings unless you understand the consequences. Note any changes so they can be reversed.
Contact the right support channel
If other apps work but one service continues to buffer, contact that provider with device details, error messages and times of failure. If everything is slow, your broadband provider may be better placed to investigate.
Do not share passwords or payment-card details with unknown people offering to fix a stream remotely.
