Online Internet Speed Test
Check your ping, download and upload speeds, jitter, and packet loss. Free, with recommendations, no installation required, works in your browser.
How It Works
Server Selection — automatically selects the closest test server to you
Ping Measurement — sends a signal and measures response time in milliseconds
Download Test — downloads data and measures your connection speed
Upload Test — uploads data to the server to check sending speed
Stability Analysis — checks jitter and packet loss
Results and Recommendations — in 60 seconds you get a complete report on connection quality
What We Test
Ping (Latency / RTT)
Description: Time it takes for a data packet to reach the server and return. Measured in ms.
- 0-50 ms — ideal for video calls, gaming
- 50-100 ms — acceptable for most tasks
- 100+ ms — noticeable delays
Download Speed
Description: Speed of data transfer from server to you. Measured in Mbps.
- 2-5 Mbps — web browsing
- 10 Mbps — 1080p video calls
- 25 Mbps — 4K video
- 100+ Mbps — family with multiple devices
Upload Speed
Description: Speed of sending data to the server. Measured in Mbps.
- 2-3 Mbps — medium quality video calls
- 5-10 Mbps — HD 1080p video calls
- 10+ Mbps — streaming video, Twitch
Jitter
Description: Variation in delay between packets. Measured in ms.
- <10 ms — excellent connection
- 10-20 ms — acceptable
- >30 ms — video calls will be choppy
Packet Loss
Description: Percentage of packets that don't reach the server.
- 0% — perfect
- 0-1% — acceptable
- 1%+ — unstable connection
Overall Score
Description: Comprehensive rating based on all parameters.
- 90-100: Excellent
- 70-89: Good
- 50-69: Average
- <50: Poor
Problems and Solutions
Very High Ping (>150 ms)
Causes: Distant server, router issues, congested network.
- →Restart your router
- →Close background programs (torrents, cloud sync)
- →Connect via Ethernet cable instead of Wi-Fi
- →Contact your ISP
High Jitter (>20 ms)
Causes: Unstable Wi-Fi, interference, network congestion.
- →Switch to wired connection (Ethernet)
- →Restart your router
- →Disconnect other Wi-Fi devices
Packet Loss (>0.5%)
Causes: Unstable connection, router problems, poor Wi-Fi.
- →Use wired connection (Ethernet)
- →Restart modem and router
- →Update router firmware
Download Slower Than Promised
Causes: Many users on network, Wi-Fi issues, peak hours.
- →Use Ethernet cable
- →Close programs with internet access
- →Test at different times (usually faster at night)
Very Slow Upload
Causes: Asymmetric connection (this is normal), high load.
- →This is NORMAL for home internet
- →Check speed in your plan
- →Use Ethernet connection

Recommended: 150-300 Mbps
About Units of Measurement
Mbps vs MB/s — what's the difference?
| Term | Full Name | Meaning |
|---|---|---|
| Mbps | Megabits per second | Smallest unit of data |
| MB/s | Megabytes per second | 1 byte = 8 bits |
Formula: MB/s = Mbps / 8
Examples:
- Test shows: 100 Mbps = actual speed 12.5 MB/s
- Contract: "100 Mbps" = this is Mbps, not MB/s!
- Download: "2 MB/s" = 16 Mbps in contract units
Frequently Asked Questions
Why do results differ from other services?
Each test selects different servers, network conditions change daily. Differences of 5-10% are normal. If difference is >50% — problem is on your side.
Test shows 100 Mbps, but I'm paying for 300. Why?
Possible reasons: using Wi-Fi (weak signal), updates downloading in background, many devices connected, peak hours (evening), ISP equipment issues.
Is it safe to run the test?
Yes, completely safe. The test only sends and receives small data packets. No personal data is collected or transmitted.
How to improve internet speed?
Use Ethernet instead of Wi-Fi (20-40% faster), restart modem + router, upgrade router if older than 5 years, switch to 5 GHz Wi-Fi channel, place router in center of room.
What is asymmetric internet?
When download is faster than upload. For example, 100 Mbps download vs 10 Mbps upload. This is NORMAL for home internet — people download more than they upload.
