Internet Speed Test
Test your internet speed for free: measure download speed, upload speed and ping in seconds. Check your WiFi or broadband connection - no app needed.

Measured against Cloudflare's nearest server. Each test uses roughly 8 seconds per direction, so fast connections transfer more data.
Ping
The round-trip time to the server: how quickly your connection responds. Under 50 ms feels instant in calls and games.
Jitter
How much ping varies between requests. High jitter causes choppy calls and lag spikes even when ping looks fine.
Download & upload
How much data your connection moves per second, in megabits. Upload matters for video calls and sending files.
About this tool
Measure what your connection actually delivers — download speed, upload speed, and ping — and compare it against what your ISP sells you. Run before the video call, after the router reboot, and whenever streaming stutters into a buffering wheel.
How to Test Your Internet Speed
- 1
Start the test — transfers run against Cloudflare's nearest test server to exercise your connection in both directions.
- 2
Wait the few seconds it takes to measure download throughput, upload throughput, and round-trip latency.
- 3
Read your results in Mbps and milliseconds, and compare them against your plan's advertised numbers.
Why Test Speed with Wrklyst
- Just the Measurement
- A clean test without an ISP's marketing wrapper — no upsell banners interpreting your results generously.
- All Three Numbers
- Download gets the headlines, but upload and ping decide video calls and gaming — you get the full triad.
- Test Freely, Test Often
- Diagnosis takes repeated measurements at different times and rooms — unlimited runs make that practical.
Connection Diagnosis Tips
- Test wired first to establish the baseline; every WiFi measurement is 'baseline minus WiFi problems'.
- Pause cloud backups and updates before testing — background transfers eat the measurement.
- Evening slowdowns with fine mornings point to neighborhood congestion — log both for the ISP call.
- Video calls choking despite fast download? Look at the upload figure — it's usually the bottleneck.
Frequently asked questions
What speeds do common activities actually need?
Less than marketing suggests: HD streaming wants ~5 Mbps and 4K about 25 per stream; video calls need 3–5 down and — the surprise — similar upload; gaming cares almost entirely about ping, not bandwidth. A 100 Mbps plan is ample for most households; instability, not headline speed, causes most misery.
Why is my result lower than my plan's advertised speed?
Advertised speeds are 'up to' figures measured to the router over cable. Real-world results subtract WiFi loss (the usual culprit — distance, walls, band congestion), device limits, network sharing, and peak-hour congestion. Test wired or beside the router: matching there but failing across the house means WiFi, not ISP.
What is ping and when does it matter?
Ping is the round-trip time for a packet, in milliseconds — responsiveness, as distinct from capacity. Under 20ms is excellent, under 50 fine for gaming, and past 100 conversations and games feel laggy regardless of bandwidth. High bandwidth with high ping streams movies beautifully and plays shooters terribly.
How do I get results my ISP will take seriously?
Build a log: test wired to the router, at consistent times including evenings, over several days, and record the numbers. A pattern of measurements at half the advertised rate — on ethernet, ruling out WiFi — is a complaint support can't deflect with 'restart your router'.
