How to fix issues with slow loading or buffering

Why it occurs in the first place

When you watch IPTV, the video stream isn’t sent to your device in one go. Instead it’s sent in bite-size ‘packets’. If there’s a delay – often caused by a slow network – your show pauses while it waits for the next packet. This is known as buffering.


Reduce the number of devices in use

Having multiple devices on your internet network can slow loading time. Are you or someone else using a games console, mobile phone, tablet, PC or Mac on the same network? Disconnecting them should help speed up your streaming.


Stop large downloads

Stop any large downloads

If you’re playing online games, downloading or uploading large files while trying to watch a show, this streaming of heavy data could cause buffering.


Test Internet connection speed

Test your internet connection speed

At busy times, some internet service providers may deliberately slow down your connection. If you’re using Wi-Fi or broadband, you need a speed of at least 10Mbps. For 3G or 4G devices the minimum speed needed is 5Mps.

If you are experiencing buffering or freezing while watching Sling TV on your device, you may be experiencing a decrease in the internet bandwidth available to your device. This decrease usually occurs when several internet-connected devices – such as phones, laptops, game systems, and tablets – use the same internet connection. Every device on your home network shares a portion of your available bandwidth, which means that less bandwidth is available for each device to perform online tasks. When trying to watch TV, this limited bandwidth can affect streaming quality.
