Internet speed test
Before you blame a driver, check the line. This free test runs in your browser, takes about twenty seconds, and returns three numbers — download, upload and latency — with nothing to install and no account to create.

What it measures
Download
How much data arrives at once — measured in Mbps with several parallel transfers. It decides stream quality, download times and how many devices the line can carry.
Upload
How much you can send. Video calls, screen sharing, cloud backups and photo sync all depend on it, and it is nearly always the lower of the two numbers.
Latency
The round-trip time in milliseconds. It decides how responsive a connection feels — games and calls live or die on this figure, not on raw speed.
20 seconds
One run, start to finish.
Free, no account
No sign-up, no software, no ads.
65 MB per run
Data used to measure throughput.
How to use it
- 01
Close anything using the line
Pause large downloads, streaming, cloud backups and other devices in the house. They share the connection, so the result comes back lower than the line really delivers.
- 02
Start the test and leave the tab open
It measures latency first, then download with parallel transfers, then upload. About twenty seconds in total, and roughly 65 MB of data used per run.
- 03
Run it twice — Wi-Fi, then cable
The wired figure shows what the line delivers; the wireless figure shows what the device actually gets. A large gap points at the router, the distance or the adapter.
Reading the result
Under 25 Mbps
One person browsing, email and music. About one HD stream.
25–100 Mbps
Three or four people, several devices, one or two HD streams.
100–500 Mbps
Several 4K streams, large game downloads, cloud backups at once.
500 Mbps and up
Large households or daily multi-gigabyte transfers. Wi-Fi is usually the limit past this.
10 Mbps upload
Comfortable video calls, photo backup and screen sharing.
Under 40 ms latency
Calls and games feel responsive. Past about 100 ms everything feels delayed.
Speeds are megabits per second, not megabytes — divide by eight for file size, so a steady 100 Mbps moves about 12 MB every second. Latency is separate: it decides how snappy the connection feels, not how fast it is.
Questions
- Does the test install anything?
- No. It runs in the browser, needs no account, and takes about twenty seconds from first number to last.
- Why is my result lower than the plan I pay for?
- Provider figures are “up to” speeds measured on a cable with nothing else running. Wi-Fi distance and walls, an older router, other devices streaming and a VPN all sit between the promise and your device.
- Does the test use my data allowance?
- Yes — about 65 MB per run, downloaded and uploaded to measure throughput. Worth remembering on a metered connection.
- I am here because a download was slow. What now?
- Test by cable first. If the wired figure is fine, the bottleneck is your wireless side; if it is also low, the package you pay for — not the driver — is the ceiling.
