Speed test: measure your internet speed
The test runs on Ookla’s Speedtest Custom service and measures the connection from your device to a test server. To see whether you get what you pay for, run it the way we explain below.

How to test properly
- Connect the computer to the router with an Ethernet cable. Wi-Fi loses speed with distance and walls, so the result measures the Wi-Fi, not the line.
- Stop downloads, streaming and updates, on this device and on the others at home. Anything running at the same time shares the line.
- Run the test two or three times, at different times of day. A single run can land on a busy moment.
- On a fibre line, check that the router port and the computer’s network card are gigabit. A 100 Mbit/s port caps the result below 100 Mbit/s.
What the numbers mean
| Measure | What it tells you |
|---|---|
| Download | How fast data reaches you, in Mbit/s. This is the number to compare with your plan. |
| Upload | How fast you send data, for video calls, backups and file uploads. On VDSL it is usually far lower than download. |
| Ping | How long a small packet takes to reach the server and come back, in ms. Lower is better for games and video calls. |
| Jitter | How much the ping varies from packet to packet, in ms. High jitter breaks up calls and games even when the speed is good. |
What speed to expect
The ranges are the ΧΕΜΔ speed bands each technology usually falls in. Your own line depends on your plan and on the length of the copper.
| Technology | Download | What limits it |
|---|---|---|
| ADSL | 2–30 Mbit/s | Distance from the telephone exchange, where the copper starts. |
| VDSL | 10–300 Mbit/s | Distance from the cabinet, the VDSL2 profile and vectoring. |
| FTTH | 100 Mbit/s or more | The plan you pay for and the equipment at home, not distance. |
Profile 17a reaches at most 150 Mbit/s down and 50 Mbit/s up in theory, and 35b 300 and 100 Mbit/s, only on very short lines.

Does your address have fibre?
If a VDSL line measures low, distance from the cabinet is the usual cause. Search your address on the map to see whether fibre has reached the building, where your street cabinet is and which telephone exchange serves you.
