Does IPTV slow down your internet?
Does watching IPTV slow down the rest of your internet? How much of your connection a stream uses, when it matters, and how to keep everyone happy.
Quick answer
IPTV uses part of your connection while a stream plays, roughly 10 to 20 Mbps for HD and 25 Mbps or more for 4K. On a fast line you will not notice; on a slow or shared line, several streams can slow other devices. QoS on the router keeps calls and games smooth.

IPTV does not slow your line in general; it shares it. Each stream takes a slice while it plays.
How much it takes
| Your line | One HD stream | One 4K stream |
|---|---|---|
| 50 Mbps | Noticeable but fine | Half the line |
| 100 Mbps | Barely noticeable | A quarter |
| 300 Mbps+ | Not noticeable | Not noticeable |
Keep everyone happy
- Use router QoS to prioritise video calls or gaming.
- Choose HD instead of 4K on secondary TVs.
- Stop streams nobody is watching.
