💡 What is Speed Test and why is it needed?
The Speed Test is a tool that measures the actual speed of your internet connection. It checks how fast your computer or mobile can downloaded (download) and upload (upload) data, as well as the delay (ping), that is, how long it takes for a data packet to get from you to the server and back.
With the speed test you can:
- Check if the speed you receive corresponds to your package.
- See how speed is affected by distance from the router.
- You compare results between different devices.
- Detect problems with the line or Wi-Fi network.
🎯 When should you do a speed check?
Speed checking isn't something you need to do every day — but there are certain times when it can come in handy.
- When you feel like your Wi-Fi is “crawling” — If videos and pages are slow to load.
- After changing provider or package — To make sure you get the speeds promised.
- When you change router or device location — To see how coverage is affected.
- Before you video conference or stream — To make sure the connection is stable.

📝 How to prepare for a reliable measurement
To get the most accurate results from a speed test, it's important to follow a few basic preparation steps. This will help you avoid misleading readings that can make you think your line is slower than it actually is.
- Connect your device with an Ethernet cable — If you can, choose a wired connection instead of Wi-Fi.
- Close all applications that use the Internet. — E.g. YouTube, Netflix, cloud backup or torrent clients.
- Disable VPNs or proxies — They can significantly reduce speed.
- Do the test near the router. — If you are measuring via Wi-Fi, stay as close to the device as possible.
- Repeat the measurement. — Do 2-3 tests and keep the average.
🔍 What do the results mean?
When the speed test is complete, you will see three main values: Download, Upload and PingThese metrics determine the overall performance of your connection and show where there may be a problem.
- Download: The speed at which you download data from the internet — the higher the better. It's important for streaming, downloads, and general browsing.
- Upload: The speed at which you send data — affects video calls, file transfers, and online gaming.
- Ping (Latency): It measures how quickly the network "responds." Lower ping means faster response, ideal for gaming and video conferencing.
- Jitter: Ping fluctuation — if it is high, it can cause interruptions or delays in communication.
📊 What speed do you need for each use?
Not everyone needs the same internet speed. Depending on what you do online, your needs may vary significantly. Below you will find a practical guide to which speed is suitable for each use, to avoid delays and buffering.
-
Basic Browsing & Email (1-5 Mbps):
It is sufficient for simple web browsing, social media, and email. It is not suitable for streaming or large downloads. -
SD quality streaming (3-5 Mbps):
Ideal for YouTube or Netflix in low resolution. If multiple devices are using the network at the same time, buffering may occur. -
HD Streaming – 720p/1080p (5-25 Mbps):
Suitable for Netflix, Disney+, YouTube in HD. One device will play comfortably, while for multiple simultaneous devices you need higher speed. -
4K/UHD streaming (25-50 Mbps):
For Ultra HD content, you need at least 25 Mbps per device. If two people are watching 4K at the same time, 50+ Mbps is preferred for a smooth experience. -
Online Gaming (10-25 Mbps + low ping):
Games don't require huge speed, but they do need stable connection and low ping (under 50 ms) for fast reactions and smooth gameplay. -
Video Calls & Teleworking (10-30 Mbps):
For Zoom, Teams, or Google Meet, you need at least 10 Mbps (ideally 20+ Mbps) and good upload speed so that others can see you clearly without interruptions. -
Large Downloads & Smart Home (50-100+ Mbps):
If you frequently download large files or games, or have many smart devices (cameras, smart TV, IoT), you need at least 50-100 Mbps to keep everything running smoothly at the same time.
⚠️ Common measurement errors
Many users make mistakes when measuring speed, resulting in misleading results. If you avoid these common mistakes, you will have a much more accurate picture of your actual speed.
-
❌ Remote Wi-Fi measurement:
Wi-Fi weakens with distance and obstacles (walls, doors). If you measure from the other room, the speed will be lower than the actual capacity of your line. -
❌ Active applications in the background:
Torrent clients, cloud backup (Dropbox, Google Drive), updates, and streaming apps eat up bandwidth even if you're not looking at them. Close them all before the test. -
❌ Use VPN during the test:
VPNs can reduce your speed by 20-50% or more, depending on the server you're using. Disable it before measuring. -
❌ Measure only once:
Speed may fluctuate due to network traffic. Take at least 2-3 measurements and average. -
❌ Comparison with other devices at home that are online:
If others in the house are watching Netflix or downloading, your reading will be lower. Make sure no one is using the internet during the test. -
❌ Measurement with old device:
An old computer or phone with an old network card may not support high speeds. Try with a newer device for more accurate results.
🔧 How to improve your speed
If your speed test results aren't satisfactory, don't despair — there are several things you can try to improve the speed and stability of your connection.
-
🔌 Use an Ethernet cable where you can:
A wired connection is always faster and more stable than Wi-Fi. Perfect for gaming, streaming, and working from home. -
📍 Place the router in a central location:
Don't hide it in a closet or corner. Put it in an open space, high up (e.g. on a shelf), away from metal objects and electronic devices that may cause interference. -
📡 Change Wi-Fi channel:
If many neighbors are using the same channel, there may be interference. Go into your router settings and try a different channel (especially on 2.4GHz). -
🔄 Restart the router regularly:
A simple restart can solve many problems. Do it once a week or whenever you feel your connection is slow. -
🛡️ Update the router firmware:
Manufacturers release updates that improve performance and security. Check your router settings to see if there is a newer version. -
📶 Use a Wi-Fi extender or mesh system:
If your home is large or has multiple floors, a repeater or mesh network (e.g. Google Nest, TP-Link Deco) can dramatically improve coverage. -
🔐 Change Wi-Fi password:
If someone unauthorized uses your network, your speed will be affected. Use a strong WPA3 or WPA2 password. -
⚙️ Upgrade the router:
If your router is old (5+ years), it may not support newer protocols like Wi-Fi 6 which offer much better speeds and coverage. -
📞 Contact your provider:
If you've tried everything and your speed is still much lower than your plan, there may be a problem with your line. Call support.
❓ Frequently Asked Questions
1. Why is my speed lower than the package I pay for?
Providers usually give the maximum theoretical speed ("up to 100 Mbps"), not the minimum guaranteed. Factors like distance from the center, line quality, time of day, and Wi-Fi can reduce the actual speed. Generally, if you get 80-90% of the promised speed, you're fine.
2. How often should I do a speed test?
You don't need to do this every day. Once a month is enough to monitor performance. Only do it more often if you're experiencing problems or if you've changed something in your layout.
3. What is better — Wi-Fi or Ethernet?
The Ethernet is always better when you need stability and maximum speed (gaming, 4K streaming, video calls). The Wi-Fi it is convenient for mobile devices but more vulnerable to interference and speed losses.
4. What does ping mean and why is it important?
The ping (or latency) measures how quickly the network "responds" to your request. Low ping (under 30 ms) is great for gaming and video calls. High ping (over 100 ms) causes lag and delays.
5. Can I increase my speed without changing package?
Yes! Try: optimizing router location, using Ethernet, changing Wi-Fi channel, restarting router, updating firmware, disabling unnecessary devices from the network. Many times the problem is not the line, but the way we use it.
6. Does VPN affect my speed?
Yes, absolutely. VPNs encrypt your data and route it through remote servers, which can reduce speeds by 20-70% depending on the server and service. If privacy isn't a priority, turn it off for better performance.
7. What is the difference between 2.4GHz and 5GHz Wi-Fi?
The 2.4GHz it has a longer range and goes through walls better, but it is slower and more prone to interference (many devices use it).
The 5GHz It is much faster but has a shorter range and has difficulty passing through obstacles. Ideal for nearby devices that need high speed.
