Do you notice that the Internet connection is slower than usual at your home or office? Before contacting your provider, you can find out exactly the actual speed you receive, both in ADSL, optical fiber as in Mobile dataMeasuring your connection speed has become a simple task thanks to online tests, applications, and specialized tools that provide you with key information about your network.
In this article, you'll find a complete and up-to-date guide to checking the speed of any type of connection (ADSL, fiber, 3G, 4G, 5G, etc.). You'll learn how to interpret the results, what factors influence the measurements, and how to improve the quality of your connection.
What is an internet speed test and what is it for?
Un speed test It is a quick, automated test that measures different parameters of your Internet connection. With it, you get values such as download speed, upload speed, latency (ping) and in some cases, the stability (jitter)These results allow you to:
- Check if you are receiving the contracted speed with your operator.
- Detect network problems (congestion, router failures, WiFi interference, line failures…)
- Compare performance of your connection on different devices, locations or times of day.
- Make informed decisions about change rate or provider if the actual speed does not match what was promised.
How do speed tests work?
These types of tests work very similarly regardless of the operator or page where you perform the test:
- The test automatically locates a test server close to your location to minimize interference.
- Send a data packet from your device to the server and back –ping or latency measurement– to know the response time in milliseconds.
- Download a file from the server, measuring the time and amount of data – this is how the download speed–.
- Then perform the reverse process: asks you to upload a file from your device to the server to measure the upload speed.
- In some cases, it monitors the stability of the connection and records fluctuations called jitter.
The information is displayed in real time and at the end you can share your results, save them or analyze them with historical data if you repeat the test periodically.
What data does a speed test provide?
- Ping or Latency: The time it takes for a packet to travel to the server and back. The lower the time, the faster your online response. Essential for gaming, video calls, and real-time activities.
- Download speed: It's the maximum capacity your device can receive data from the Internet. It determines how quickly you can watch videos, download files, browse, or stream.
- Upload speed: Indicates the maximum speed at which you can send data to the network (upload videos, attachments, back up to the cloud, etc.).
- Jitter: Measures the variation in packet delivery time. A stable connection shows low jitter values.
- Public IP address: In some tests, you can see the assigned IP and your operator.
Step by step: How to measure the speed of your ADSL, fiber optic, and mobile connection
- Choose the right device: You can perform the test from a PC, laptop, tablet, or smartphone. For maximum speed, connect your computer to your router using an Ethernet cable.
- Find a reliable speed test: Type “speed test” into any search engine and select recognized platforms such as Speedtest by Ookla, Fast.com, nPerf, or operator-specific tests (Movistar, Orange, Vodafone, Digi, O2, etc.).
- Prepare your network for real results:
- Close programs and apps that consume bandwidth (downloads, online games, streaming, etc.)
- Disconnect any other devices connected to your WiFi or wired network, except the one you are using for the test.
- Whenever possible, perform the test connected by straight Ethernet cable to the router.
- For mobile connections, position yourself in an open area with maximum coverage.
- Avoid running the test during automatic downloads, cloud syncs, or system updates.
- Click “Start Test”: Please wait a few seconds while the ping, download, and upload tests complete.
- Analyze and save the results: Record your data or use the sharing/certification tools offered by most platforms.
Interpreting the results: What is a good internet speed?
- ping: Less than 50 ms is excellent; between 50 and 100 ms is acceptable; above 100 ms can affect real-time applications.
- Download speed: For basic browsing and email, 10 Mbps is sufficient. HD streaming requires at least 20-30 Mbps. Large or 4K downloads require 100 Mbps or more. Fiber connections typically offer 100 to 1000 Mbps or more.
- Upload speed: Essential for video calls, online gaming, and file uploads. Fiber optic speeds are typically symmetrical. ADSL speeds are much slower than download speeds.
- Jitter: Values below 30 ms are ideal to ensure stability.
Important Note: It's normal for actual speeds to be slightly lower than contracted due to network sharing, peak usage in the area, Wi-Fi interference, equipment limitations, etc. Most carriers guarantee around 80% of the nominal speed.
Factors affecting ADSL, fiber and mobile connection speed
- Router location and WiFi signal quality: Obstacles (walls, furniture), distance from your router, and other networks can significantly reduce speed. Whenever possible, keep your router in a central, elevated location free from electronic interference.
- Number of connected devices: Multiple devices using the Internet simultaneously decrease the speed available to each device.
- Hardware status: Computers with slow network cards, old cell phones, or outdated routers limit the maximum speed.
- Operator network load: During peak hours or due to traffic congestion, speed may be reduced.
- Presence of malware or virus: Threats or malware consume resources and slow down your connection. Always keep your computer up to date. antivirus.
- Background applications or services: Backups, synchronizations, streaming, or downloads can falsify the results if performed during the test.
- Type of connection used: Wi-Fi is more susceptible to interference than a wired connection. Mobile networks (3G, 4G, 5G) vary depending on location and coverage.
Key tips for reliable measurement and improved speed
- Close all apps and browser tabs that may be using data.
- Avoid using other devices during the test: Televisions, consoles, IP cameras and any other equipment connected to the network can alter the results.
- Place the router in a central, high, and unobstructed location. Do not place it inside cabinets, near other electrical devices, or next to microwaves or cordless phones.
- Perform several tests at different times of the day. This way, you can detect if speeds drop during rush hour and get a more precise overview.
- Always update your browser and operating system to the latest version.
- If you're using Wi-Fi, connect to the 5 GHz network if your router and device allow it. This way you reduce interference and make better use of the available bandwidth.
- If WiFi coverage is poor, use repeaters, PLCs, or mesh routers to expand your home network.
- Use Ethernet cable whenever you want an accurate measurement.
What to do if the actual speed is lower than the contracted speed?
- Make sure the device you are testing from supports high speeds. Some older laptops or cell phones limit the connection.
- Check the wiring: CAT6 or higher Ethernet cables are recommended for fiber connections.
- Restart your router or contact your operator. if you detect breakdowns or very inferior results.
- Test both wired and WiFi. If you get the correct speed via cable but not via Wi-Fi, you may experience coverage issues or interference.
- If you're using VPNs, proxies, or firewalls, they may reduce your measurable speed; temporarily turn them off.

- Mobile data (3G, 4G, 5G): Speed and latency depend on coverage, antenna saturation, and the available network. 4G typically operates between 20 and 150 Mbps. 5G easily exceeds 300 Mbps and can reach almost XNUMX Gbps under optimal conditions.
Why can speed tests vary with each measurement?
- Network congestion: It increases during peak hours, when many users share the same infrastructure.
- Internet routes: The distance to the server and the number of hops affect the speed.
- Environmental conditions: In mobile networks, weather and physical obstacles play a role.
- Automatic updates or synchronizations: While files are being downloaded or uploaded in the background, the measured speed will drop.
- WiFi Interference and Saturation: Electronic devices and other overlapping networks can reduce quality.
- Type of protocol used: Some tests use TCP or HTTP protocols, which may react differently to firewalls or operator limitations.
What to do if the actual speed is lower than the contracted speed?
- Make sure the device you are testing from supports high speeds. Some older laptops or cell phones limit the connection.
- Check the wiring: CAT6 or higher Ethernet cables are recommended for fiber connections.
- Restart your router or contact your operator. if you detect breakdowns or very inferior results.
- Test both wired and WiFi. If you get the correct speed via cable but not via Wi-Fi, you may experience coverage issues or interference.
- If you're using VPNs, proxies, or firewalls, they may reduce your measurable speed; temporarily turn them off.
Measure speed from your mobile: recommended apps for Android and iOS
You can check the speed of both your WiFi connection and the 3G, 4G or 5G mobile data with reputable and free apps:
- Speedtest by Ookla: Available for iOS and Android. Allows you to select a test server, history, coverage maps, and share results.
- Fast.com: Especially simple, perfect for checking download speed with one click.
- nPerf: It provides speed tests, browsing, streaming, and comparisons with carriers and coverage maps.
- Operator speed test (Movistar, Vodafone, Orange, Digi, O2…): You can find them in app stores or access their web sections from your mobile browser.
Step by step: measure the speed of your mobile connection
- Download and install the speed test app of your choice.
- Connect your phone to WiFi or turn on mobile data depending on what you want to measure.
- Place your phone near your router (on WiFi) or in an open area (on mobile data).
- Open the app and tap “Start.”
- Observe ping, download and upload results. Please note that the test may consume between 50 and 100 MB if performed over mobile data.
- Save or share data from the app.
