Run the speed test
Use the homepage test to measure download speed, upload speed, ping and jitter from the device you are using.
Run speed testCheck your speed, then understand the result
LinkSpeed is the actual broadband speed test. This page is the landing page for people searching for an internet speed checker. It explains what the test measures and where to go next after the result appears.
Start with the live test for download, upload, ping and jitter. Then use Internet Quality for result interpretation, Troubleshooting for faults, or Home Network Guides for Wi‑Fi and router problems.

Which guide should you use after the test?
Internet Quality
Use this hub when you want to understand ping, jitter, packet loss, loaded latency, bufferbloat and responsiveness.
Open Internet QualityTroubleshooting
Use this hub when the result points to slow broadband, high ping, buffering, Wi‑Fi dropouts or unstable service.
Open TroubleshootingHome Network
Use this hub when speeds are good near the router but poor in specific rooms, upstairs or over Wi‑Fi.

| Result | What it tells you | Best next page |
|---|---|---|
| Download speed | How much data reaches your device each second. Useful for streaming, browsing, downloads and updates. | Speed calculator |
| Upload speed | How much data leaves your device each second. Useful for video calls, cloud backups and livestreaming. | Slow upload guide |
| Ping | How quickly your connection responds. Important for gaming, calls, remote work and cloud apps. | Internet Quality Hub |
| Jitter | How much latency varies during the test. High jitter can cause lag spikes, audio glitches and unstable calls. | Internet Quality Hub |
Why speed checker results vary
Wi‑Fi conditions
Distance, walls, interference and weak rooms can reduce the result before traffic even reaches the broadband line.
Fix one slow roomRouter or Ethernet limits
Old routers, limited ports or weak Wi‑Fi standards can hold back full fibre and gigabit broadband.
Ethernet vs Wi‑FiConnection stability
A connection can have good download speed but still feel poor if ping rises, jitter jumps or bufferbloat appears.
Run bufferbloat testBusy connection
Downloads, uploads, cloud backups, game updates and other users can change the result from one test to the next.

Internet speed checker FAQs
What does an internet speed checker measure?
It measures the performance of the connection from your current device. LinkSpeed shows download speed, upload speed, ping and jitter so you can understand both capacity and responsiveness.
Why is Wi‑Fi slower than Ethernet?
Wi‑Fi is affected by distance, walls, interference, router position and device capability. Ethernet is usually the clearest way to test the underlying broadband line.
Should I use Internet Quality or Troubleshooting after a test?
Use Internet Quality when you want to understand the numbers. Use Troubleshooting when you have a symptom such as slow internet, dropouts, buffering, high ping or unstable Wi‑Fi.
