Internet Speed Test
Press start and in a few seconds you will know how fast your connection downloads and uploads. Nothing is measured until you choose to.
Is the Wi-Fi worse in another room? Run the test next to the router, press «Pin to compare» and run it again there. It measures the speed reaching this device, not the Wi-Fi signal.
The test measures against Cloudflare’s network and uses up to 190 MB of data on very fast connections, less on slower ones. Solvemis does not receive or store your results.

How it works
How to use it
- If you can, connect the computer to the router by cable, so you measure the line and not the Wi-Fi.
- Pause any downloads, streams or updates.
- Press "Start test" and wait about 20 to 30 seconds.
- You will see download, upload, latency and jitter. Repeat the test a few times.
How it is calculated
The test runs over Cloudflare's network with its open-source library, the same one speed.cloudflare.com uses. Download and upload are measured with increasingly large files, and the figure shown is the 90th percentile of all transfers. Latency is the median of 20 measurements.
Mbps = megabits per second · 1 MB/s = 8 Mbps

About this calculator
What the figures mean
Download matters most for streaming and browsing, upload for video calls and cloud backups. Latency decides whether games and calls run smoothly, and jitter shows how much it varies.
Megabits are not megabytes
Plans are sold in megabits per second, but files are measured in megabytes. A byte has eight bits: 250 Mbps downloads at most about 31 MB per second.
Privacy
The test runs between your browser and Cloudflare’s measurement servers. Solvemis does not receive or store your results.
Frequently asked questions
Why is my speed lower than the plan I pay for?
The bottleneck is usually at home: Wi-Fi, an old router or a device that can't go any faster. For comparison, test with a computer connected by cable.
