Internet speed test
Measure your download and upload speed, ping and jitter against our test server in about fifteen seconds — no Flash, no app, no account, and the result stays on your screen. Run it on Wi-Fi and on cable to see what your home network costs you.

Test server: Frankfurt, Germany (probe-fra1). The result is the throughput between your browser and that server — distance, Wi-Fi and the device limit it; it is not a national benchmark. Connection quality test
Start the speed test
Press Start. The test measures idle latency, then downloads and then uploads random data for a few seconds each while continuing to measure latency, so you also see how much your connection slows down under load (bufferbloat). Each run moves about 20 MB; mobile users on metered plans, take note.
Your results
Download and upload in Mbit/s, latency in milliseconds idle and under load, jitter and the server location.
Download
How fast data reaches you — streaming, page loads, downloads. Browser-based tests reach a few hundred Mbit/s on most devices; on gigabit lines the browser and Wi-Fi, not the line, are usually the limit.
Upload
How fast data leaves you — video calls, backups, sharing files. Cable and DSL plans are asymmetric and give far less upload than download; fiber is usually symmetric.
Ping and jitter
Round-trip time to the server and its variation. The under load figure is the one that explains lag during downloads; the connection quality test grades it.
Wi-Fi vs cable
Run the test twice, on Wi-Fi and plugged in. The difference is your Wi-Fi's share of the problem; on fast lines it is often most of it.
What is a good internet speed?
For one person: 25 Mbit/s down handles HD streaming and calls; 100 Mbit/s handles a household with 4K streaming, gaming and downloads at once; above 300 Mbit/s the difference is only noticeable for large downloads. Upload matters more than most plans admit: 10 Mbit/s is the minimum for comfortable video calls and 20+ for sharing large files or backing up. Latency and jitter decide how responsive the connection feels; a 50 Mbit/s fiber line with 5 ms latency feels faster than 500 Mbit/s cable with 40 ms and bufferbloat.
How to fix slow internet
Test on a cable first to separate Wi-Fi from the line. If the cable is slow too: restart the modem, check for firmware updates, test at a different time of day (evening congestion points to the provider), and compare with the speed you pay for. If only Wi-Fi is slow: move the router, use 5 GHz, change the channel, replace a weak router or add a mesh unit. If the speed is fine but everything lags: it is bufferbloat or packet loss — run the connection quality test. If a VPN is on, test without it; some VPN servers cap throughput.
Frequently asked questions
How do I check my exact internet speed?
Run the test above on a device connected by cable, with nothing else using the connection. Browser tests are accurate to within a few percent on connections below a few hundred Mbit/s; on faster lines, a wired desktop gives the truest figure.
What is a good internet speed today?
100 Mbit/s download and 20 Mbit/s upload covers nearly every household comfortably; 25/5 is enough for one or two people who stream and call. Latency under 30 ms matters as much as the headline number.
What is a decent internet speed at home?
For a typical home: 100 Mbit/s down, 10–20 Mbit/s up, latency under 30 ms and no bufferbloat. More download speed helps mostly for large downloads and many simultaneous 4K streams.
How do I check my house internet speed?
Run this test from a device on your home network — wired to the router for the line's true speed, on Wi-Fi for what your devices actually get.
Is 100 Mbps good?
Yes, for most households: several 4K streams, calls and gaming at once. It is only limiting for very large downloads or many heavy users.
How fast broadband do I need?
Count people and uses: one person streaming and working from home is fine with 25–50 Mbit/s; a family with 4K TVs, gaming and calls is comfortable at 100–300. Upload of at least 10–20 Mbit/s matters for calls and cloud backups.
Measured live in your browser against our own server; nothing about this run is stored or shared. Fast lines (> 500 Mbit/s) are usually limited by the browser and the test duration, not the line.
