What Does a Broadband Speed Test Measure?
A broadband speed test, sometimes called a bandwidth test, checks how quickly data downloads and uploads, then measures ping and jitter to show how responsive and stable the connection feels for browsing, streaming, gaming and video calls.
Pre-flight diagnostics
Test the weak link before changing provider or hardware
Use the speed test below as the baseline, then open the focused check that matches the symptom. Comparing Wi-Fi and Ethernet on the same device quickly separates local wireless issues from line or router queueing.

Video calls freezing or games lagging?
Run a quick speed test to measure download, upload, ping and jitter, identify whether the issue is your Wi‑Fi, router or provider.

Slow result? Check your upgrade options
Check faster full fibre at your address
If repeated Ethernet tests are slow, enter your postcode to check Openreach FTTP, Virgin Media, CityFibre and local alt-net availability.
Connection type
Run test to classify
See whether your result looks basic, superfast, ultrafast or gigabit.
Consistency
Run test for stability
Tracks the gap between sustained average and peak download throughput. Large gaps mean the speed varied; repeat over Ethernet to separate Wi-Fi effects from the broadband line.
Note: Results are estimates. Location and ISP may be approximate, and Wi‑Fi, VPNs or congestion can affect speeds.
Privacy: The recent results feed is anonymous. It does not store IP addresses; it only shows speed, quality, broad provider/location and device-type context.

Internet and DSL speed testing
Free internet speed test for fibre, cable and DSL broadband
LinkSpeed works as an internet speed test across full fibre, cable, ADSL, VDSL/FTTC, 4G and 5G connections. It measures download and upload throughput plus ping and jitter, so you can see both speed and responsiveness.
Using it as a DSL speed test
For ADSL or VDSL/FTTC, repeat the test over Ethernet and compare the result with your router's connection or sync speed. A much lower browser result can point to congestion, Wi-Fi or another device using the line.
Speed looks fine but the connection still lags?
A normal result can miss queueing delay. Run the loaded latency test or bufferbloat test to see whether ping rises when the connection is busy.

Hardware route
If testing points to the router, not the broadband line
Do not replace working hardware from one poor Wi-Fi result. Retest over Ethernet first. If wired loaded latency is also poor, look for effective SQM or QoS. If Ethernet is good but Wi-Fi is weak or inconsistent, coverage and mesh placement matter more.

SQM / QoS route
Standalone router
For poor wired loaded latency or an ISP hub with weak queue management.
Value route
Replace the ISP hub
For users who need better controls without moving to a full mesh system.
Coverage route
Whole-home mesh
For good Ethernet results but weak, inconsistent or congested Wi-Fi.
