Line check
IPTV stability test: will your line hold a stream?
Ordinary speed tests report your best moment. This one measures the slowest speed your connection keeps steady, which is the number that decides whether a stream freezes.

Press start on the device you watch on, at the hour you usually watch. The test reports your slowest steady speed, the number that decides whether a stream freezes.
Runs in your browser against the nearest Cloudflare server and stores nothing. On a fast line it can download up to 150 MB, so avoid it on a capped mobile plan.
How to get a true result
- Run it on the device you watch on, or on a phone standing right next to the TV, on the same Wi-Fi.
- Run it at the hour you usually watch. A line that is fine at 10 a.m. can sag at 8 p.m. on game night.
- Pause big downloads, cloud backups and other streams in the house while it runs.
- Run it twice if you can: once on Wi-Fi, once with a network cable. The gap shows how much your Wi-Fi costs you.
What each number means
Steady floor
The speed your line keeps 90% of the time. We measure the speed over every rolling one-second window for seven seconds and take the 10th percentile. This is the number a player's buffer depends on.
Average speed
The mean of the same one-second windows. It is close to what an ordinary speed test shows.
Consistency
The floor divided by the median speed. 90% means your slow moments are almost as fast as your typical ones; under 60% usually points to Wi-Fi.
Latency
The median time for eight small requests to the nearest Cloudflare server. It affects how fast channels change, not picture quality.
Jitter
How much latency changes from one request to the next. High jitter with a good floor is common on busy Wi-Fi.
Streams
How many streams fit inside the floor at once, counting each stream's bitrate plus 50% headroom.
Reading your result
| Steady floor | What it means |
|---|---|
| 30 Mbps or more | 4K plays steadily, with room for other traffic in the house. |
| 15 to 30 Mbps | Full HD plays steadily. Pick the Full HD version of a 4K channel if it pauses. |
| 10 to 15 Mbps | HD plays; Full HD is borderline at busy hours. |
| Under 10 Mbps | Fix the line before you buy: a network cable or the router's 5 GHz band usually helps most. |
Steady speed to aim for, by picture quality
| Picture | Stream uses about | 1 screen | 2 screens | 3 screens |
|---|---|---|---|---|
| SD (576p) | 2.5 Mbps | 5 Mbps | 10 Mbps | 15 Mbps |
| HD (720p) | 5 Mbps | 10 Mbps | 15 Mbps | 25 Mbps |
| Full HD (1080p) | 8 Mbps | 15 Mbps | 25 Mbps | 40 Mbps |
| 4K Ultra HD | 20 Mbps | 30 Mbps | 60 Mbps | 90 Mbps |
Screen columns are the steady speed to aim for: the stream rate plus 50% headroom for Wi-Fi loss and other traffic in the house, rounded up to the next 5 Mbps.
Why the floor matters more than the average
A player keeps a few seconds of video in a buffer. While your line delivers more than the stream needs, the buffer stays full; when it delivers less, the buffer drains, and when it is empty the picture freezes.
So a line that averages 60 Mbps but drops to 8 Mbps for a few seconds every minute can freeze a Full HD stream, while a steady 20 Mbps line never will. The steady floor catches those dips; an average hides them.
What this test cannot see
- It measures your connection to the nearest Cloudflare server, not to our streaming servers. It tells you what your line can carry, which is the part most often at fault.
- Run on a phone, it measures the phone's Wi-Fi, not the TV's. A TV in another room can get much less.
- It is one moment in time. The 24-hour trial is the full test: a live game, on your TV, at peak time.
Stability test questions
Is this the same as a normal internet speed test?
No. A normal speed test reports your peak or average speed. This test also reports your steady floor, the speed your line keeps during its slow moments, because that is what decides whether IPTV buffers.
How much data does the test use?
It downloads for about eight seconds. On a fast line that can reach 150 MB, which is the cap; on a 25 Mbps line it uses about 25 MB. Avoid running it repeatedly on a capped mobile plan.
Why is my floor much lower than my internet plan's speed?
Usually Wi-Fi: distance, walls and neighbours' networks cut speed and make it swing. Run the test again with a network cable. If the cable result is also low, check it at different hours; evening congestion at your provider is the next most common cause.
Does the test store my results or my IP address?
No. It runs in your browser and nothing is saved or sent anywhere except the test downloads themselves.
My result says HD only. Can I still subscribe?
Yes, if HD is enough for you: every main channel has an HD version. Try it first with the free 24-hour trial, and remember the 7-day money-back guarantee on your first order.
