What internet speed do you actually need for IPTV in 2025?

Before setting anything up I want to understand the real speed requirements. I keep reading different numbers — some say 10 Mbps is enough, others say you need 50 Mbps. My broadband package is 100 Mbps but I share it with two other people in the house. Is that going to be enough for a good quality IPTV experience?
 
The numbers you read are usually per-stream bitrates, not your total broadband speed. For standard HD (1080p), a single stream needs around 8–12 Mbps sustained. For 4K HDR it jumps to 25–35 Mbps depending on the encoding. So 100 Mbps shared across three people is more than enough for one or two simultaneous HD streams.
 
Key word there is "sustained" — not just your headline speed. Run a test at 8pm on a weekday, not at 2pm on a Sunday. Many broadband packages advertise fast speeds that drop significantly during evening peak hours. That evening figure is what matters for IPTV.
 
I have 80 Mbps fibre and had buffering problems until I figured out it was dropping to around 22 Mbps between 7 and 10pm. Switched to a less congested ISP and the problem disappeared entirely. The speed number on your contract is not always what you actually get.
 
Ireland user here — 100 Mbps is plenty if you can keep your streaming device on Ethernet. The connection consistency matters more than raw speed. Wi-Fi at 100 Mbps can behave worse than Ethernet at 30 Mbps because of packet loss and latency spikes.
 
To add some numbers: IPTV streams are continuous real-time data. Even 0.5% packet loss causes visible buffering or stuttering on a live stream because the player cannot buffer ahead like a YouTube video does. Ethernet eliminates almost all packet loss. That is why wired is always recommended.
 
Canada here — our household has three streamers going at the same time on a 150 Mbps connection without any issues. As long as the base speed is above 50 Mbps and the router is decent, simultaneous viewing is fine for normal HD content.
 
What about 4K specifically? We just got a new TV and want to use it to its full potential.
 
4K needs sustained 25–35 Mbps reliably. On a 100 Mbps shared connection, 4K is absolutely possible but I would strongly recommend Ethernet for the 4K TV to guarantee consistency. Wi-Fi can struggle to maintain that sustained throughput during peak hours.
 
Also worth noting: the "4K" label on streams varies a lot. Some are true 4K HDR at high bitrates, others are upscaled 1080p labelled as 4K. True 4K HDR is the demanding one. If channels feel fine at 1080p but buffer at 4K, it is almost always a sustained bitrate issue rather than overall speed.
 
Summary from someone who has tested this thoroughly: 25 Mbps minimum for HD-only viewing, 50+ Mbps recommended if you want 4K on one TV plus HD on another simultaneously. And regardless of speed, use Ethernet on your main viewing device.
