Internet Speed Test
Test your internet connection speed. (Simulated results)
Input Information
Internet Speed Test
This test provides simulated results and may differ from actual internet speed.
Result
Results will appear when you start the test.
Internet Speed Test A tool that measures your internet connection's download/upload speed and ping latency. Quickly check if your home or office line meets advertised speeds, and if online gaming or video conferencing will be smooth.
Useful for remote workers, gamers, video streaming users, and network administrators. Identify the gap between ISP contracted speed and actual perceived speed.
A diagnostic tool for beginners finding slow internet causes, and a first-response tool for IT staff handling incidents. Measurements are more reliable when averaged over multiple runs.
This tool provides simulated results for reference only. For accurate measurements, use dedicated services like Speedtest.net or Fast.com. Results vary significantly based on measurement environment (WiFi, wired, other device usage).
Term Glossary
- Ping / Latency
- Round-trip time (ms) for data to reach the server and return. Lower values mean faster response, especially important in online games and video conferencing.
- Mbps (Megabits per Second)
- Internet speed unit indicating data transferred per second. Higher numbers mean faster. 8 Mbps ≈ 1 MB/s.
- Download / Upload Speed
- Download is speed receiving data from the internet; upload is speed sending data from your device. Home lines typically have faster download than upload.
- Jitter
- Variation in ping latency. Lower means more stable connection; higher causes stuttering in calls and games.
- Click the start test button.
- Wait while download, upload, and ping results are measured.
- Review the performance grade and judge whether your speed is adequate.
100Mbps Plan
For a 100Mbps plan, the actual download speed typically measures 85-95Mbps due to network overhead, which is normal.
Gaming Ping
A ping under 20ms is ideal for online gaming, and 20-60ms is still playable smoothly for most games.
High Latency
When ping exceeds 100ms, delays become noticeable in video calls and gaming; a wired connection or closer server can help.
Ping Measurement
Sends packets to the server and measures round-trip time.
Download Speed
Calculates speed based on time to receive a certain amount of data.
Upload Speed and Jitter
Jitter is the variation in ping latency — lower is better.
Wired Connection
- Use an Ethernet cable to eliminate WiFi interference.
- Closer to the router means more stable results.
Other Devices
- Stop other devices' streaming/downloads during testing.
- Background updates also consume speed.
VPN Disable
- VPN use increases latency due to encryption overhead.
- Disable VPN to see pure line speed.
Repeat Measurement
- Measure multiple times and compare average and minimum.
- Network congestion varies by time of day.
Speed Reference
- Web/HD 5~10 Mbps, 4K 25 Mbps, Video Conference 10~20 Mbps recommended.
- Online games benefit from ping under 20 ms.
Troubleshooting
- Restart router and check firmware first if slow.
- Contact ISP for line inspection if issues persist.
QWhat is the difference between Mbps and MBps?
Mbps is megabits per second and MBps is megabytes per second. Since 1 byte equals 8 bits, 100Mbps is about 12.5MBps.
QWhy is my measured speed lower than my plan?
Actual speed is typically lower than your plan's maximum due to network overhead, WiFi interference, server distance, device performance, and concurrent users.
QWhat does ping (latency) mean?
Ping is the time in milliseconds for data to travel to a server and back. Lower values mean faster response, which matters for gaming and video calls.
QDoes the server location affect the results?
Yes. Closer servers tend to give lower ping and higher measured speeds. Testing against servers in different regions shows the difference distance makes.
QWhat factors affect the speed?
WiFi signal strength, time of day (congestion), number of connected devices, router performance, and cabling all affect results. A wired connection and testing during off-peak hours are more reliable.
