NETPULSE PRORun Speed Test

Fiber Speed Test

Fibre plans promise symmetric gigabit speeds — this test confirms you're actually getting them. Measure download, upload, latency and bufferbloat and see the full speed curve.

Gigabit-ready

Parallel connections and multiple servers let the test push high-speed fibre lines to their limit.

Symmetric check

Fibre should give near-equal upload and download — verify both in one test.

Latency & bufferbloat

Fibre's low latency is its superpower. Confirm yours stays low even under full load.

Getting an accurate fibre reading

To measure a fast fibre line accurately, test on a device connected by Ethernet — most Wi-Fi and many older laptops can't sustain gigabit speeds, so a wireless test will understate your line. Use a Gigabit or 2.5G Ethernet port and a Cat 5e or better cable.

  1. 1Connect your computer to the router with an Ethernet cable.
  2. 2Close other devices and downloads on the network.
  3. 3Run the test and check that download and upload are both close to your plan.
  4. 4Confirm latency stays low and bufferbloat stays minimal under load.

What good fibre numbers look like

On a gigabit fibre plan, expect download and upload both in the high hundreds of Mbps to ~940 Mbps (the practical ceiling of a 1 Gbps line after overhead), latency in the low single digits to low tens of milliseconds, and negligible bufferbloat. If upload is far below download, your plan may be asymmetric fibre rather than true symmetric fibre.

Frequently asked questions

How do I test my fiber internet speed?+

Connect a computer to your router with an Ethernet cable, close other devices, and run the test. A wired connection is essential — Wi-Fi usually can't sustain gigabit fibre speeds and will understate your line.

Why isn't my fiber hitting 1000 Mbps?+

A 1 Gbps line tops out around 940 Mbps after protocol overhead. Beyond that, a Wi-Fi connection, an older network card, a slower-than-gigabit Ethernet port, or a Cat 5 cable can all cap your result below the line's capability.

Should fiber upload equal download?+

True symmetric fibre gives near-equal upload and download. Some providers sell asymmetric fibre with lower upload, so check your plan if the two numbers differ significantly.
