You are in a video call and the video keeps freezing. Your YouTube video buffers for 30 seconds before playing. Is it your internet connection — or something else? A quick internet speed test tells you exactly what is happening. Here is how to do it and what the numbers mean.
What Does an Internet Speed Test Measure?
A speed test measures three things:
- Download Speed (Mbps): How fast your connection can receive data from the internet. This affects streaming, browsing, and downloads.
- Upload Speed (Mbps): How fast your connection can send data to the internet. This affects video calls, cloud uploads, and gaming.
- Ping / Latency (ms): How long it takes a signal to travel from your device to a server and back. Lower is better. High ping causes lag in video calls and online games.
How to Run an Internet Speed Test
- Close all other browser tabs and pause any downloads.
- Connect your device directly to your router via ethernet cable (for the most accurate wired speed) OR stay on Wi-Fi for your typical real-world speed.
- Go to our Internet Speed Test tool.
- Click Start and wait about 30 seconds.
- Read your download speed, upload speed, and ping results.
What Are Good Internet Speeds?
- Basic browsing and social media: 5-10 Mbps download is sufficient.
- HD video streaming (Netflix, YouTube): 15-25 Mbps recommended.
- 4K streaming: 25 Mbps minimum per stream.
- Video calls (Zoom, Google Meet): 3 Mbps download + 3 Mbps upload minimum. 10 Mbps recommended for HD.
- Online gaming: Speed matters less than ping. Under 30ms ping is ideal; above 100ms causes noticeable lag.
- Working from home: 50+ Mbps shared connection for multiple users.
Why is My Speed Slower Than What I Pay For?
ISPs sell speeds as "up to" — meaning those speeds are theoretical maximums. Factors that reduce actual speeds include:
- Wi-Fi signal strength and distance from router
- Network congestion during peak hours (evenings)
- Old router or modem hardware
- VPN usage (reduces speed by 10-30%)
- Multiple devices sharing the same connection

Why do I get different speeds at different times of day?
Internet speeds vary based on network congestion. Evening peak hours (8-11 PM) typically have the most congestion. Testing in the morning or early afternoon gives more accurate baseline results.
Should I test on Wi-Fi or ethernet?
Ethernet cable gives you the true maximum speed of your connection. Wi-Fi introduces additional variables. For everyday browsing, Wi-Fi speed is what matters most.
My download speed is fine but video calls are choppy — why?
Video calls require good upload speed AND low ping. Check your upload speed — if it is below 3 Mbps, that is likely the cause. High ping (above 80ms) also causes choppiness in real-time communication.
Can a speed test use a lot of data?
A typical speed test uses approximately 100-300 MB of data. If you have a limited data plan, be mindful of this.
