Understand Your Internet

Simple explanations for the numbers behind your connection.

01

What is Internet Speed?

Internet speed describes how quickly data can move between your device and the Internet. It is usually measured in Mbps (megabits per second).

Download speed affects websites, downloads, streaming and browsing. Upload speed matters when sending files, uploading videos, making video calls, live streaming and backing up data.

A higher speed is useful, but speed is not everything. Ping, jitter, packet loss, Wi-Fi quality and network congestion can also affect your experience.

02

What is Ping?

Ping, also called latency, measures how long it takes for a request to travel to a server and for the response to return. It is measured in milliseconds (ms).

Lower ping means less delay. Ping is especially important for online gaming, video calls, remote work and other real-time activities.

Under 20 ms is excellent, 20–50 ms is very good, 50–100 ms is good, while 100 ms or more can introduce noticeable delay.

03

What is Jitter?

Jitter measures how much the timing of network packets changes from one moment to another. It is measured in milliseconds (ms).

Lower jitter means a more consistent connection. High jitter can cause audio problems, unstable video calls, inconsistent gaming and uneven communication.

Jitter is especially important when data needs to arrive smoothly and consistently rather than simply arriving quickly.

04

Why Can Wi-Fi Be Slow?

Slow Internet is not always caused by your Internet provider. Your Wi-Fi environment can also affect connection performance.

Common causes include distance from the router, walls, wireless interference, too many connected devices, router limitations and network congestion.

Better router placement, fewer obstacles, updated equipment and a less congested wireless environment can sometimes improve Wi-Fi performance.

Comparing a Wi-Fi speed test with a wired Ethernet test can help determine whether Wi-Fi is the limiting factor.

Frequently Asked Questions

Common questions about Internet speed, ping, jitter, Wi-Fi and network performance.

What is an Internet speed test?

An Internet speed test measures how quickly data can travel between your device and a test server. It can help you understand download speed, upload speed, ping, jitter and other aspects of your connection.

What is a good download speed?

The speed you need depends on how you use the Internet. Browsing and basic work require less bandwidth, while HD or 4K streaming, large downloads and multiple connected devices generally benefit from higher speeds.

What is upload speed?

Upload speed measures how quickly your device can send data to the Internet. It is important for uploading files, sending large attachments, video calls, livestreaming and cloud backups.

What is ping or latency?

Ping, also called latency, measures the response time between your device and a server. Lower latency usually means less delay, which is particularly important for online gaming, video calls and other real-time activities.

What is jitter?

Jitter describes variation in network latency over time. Lower and more consistent jitter can provide a smoother experience for gaming, voice calls and video meetings.

Why is my Wi-Fi speed slower than expected?

Wi-Fi performance can be affected by distance from the router, walls, interference, connected devices, router capabilities and network congestion. Comparing a Wi-Fi test with a wired Ethernet test can help identify whether Wi-Fi is contributing to the problem.

Why does my Internet speed change?

Internet performance can vary because of network congestion, Wi-Fi conditions, the number of connected devices, server location, routing and other network conditions. Running multiple tests at different times can provide a better picture of your connection.

Does NetSpeedCheck require an account?

NetSpeedCheck is designed to let users test their Internet connection without unnecessary signup.

Can I use NetSpeedCheck on a phone?

Yes. NetSpeedCheck is designed to work on mobile phones, tablets, laptops and desktop computers.

Does a higher speed always mean better Internet?

Not necessarily. Download and upload speed are important, but ping, jitter, packet loss, Wi-Fi quality, congestion and connection stability can also affect your experience.
