Every connection type
What speeds should you expect?
Typical speeds by access technology, from copper lines to 5G.
ADSL / VDSL
16 Mbit/sAsymmetric speeds: enough for browsing and HD TV.
Wi-Fi
500 Mbit/sYour router or the signal may cap your speed: measure it for real.
3G / 4G LTE
10 - 100 Mbit/sTest your mobile connection wherever you are.
5G
1 Gbit/sHigh speed and low latency for gaming and video.
Satellite
10 - 100 Mbit/sGood speed, higher latency, useful in remote areas.

Frequently asked questions
Speed test: your questions
Answers to the most common questions about measuring internet speed.
What is a speed test for?
A speed test measures the real speed of your internet connection. It reports download speed, upload speed, latency (ping) and jitter, so you can check that you get the service you pay your ISP for.
Why is my speed lower than advertised?
Several factors reduce speed: Wi-Fi, distance from the router, the number of connected devices, peak hours, the cable or line quality. Testing over Ethernet, with the router restarted and no downloads running, gives a more reliable result.
How do I test my Wi-Fi speed properly?
Stand close to the router, use the 5 GHz band if available and avoid thick walls. To isolate Wi-Fi, compare with an Ethernet test: if the wired speed is clearly higher, the wireless signal is the problem.
How much speed do I need for 4K and gaming?
Allow about 25 Mbit/s per 4K stream and latency below 30 ms for online gaming. Remote work and video calls mainly need stable upload and low ping.
Is the Netest speed test free?
Yes, the Netest speed test is free, with no signup and no installation. It works on computers, tablets and smartphones over fiber, ADSL, Wi-Fi, 4G or 5G.
