Which speed test is the most reliable

Speed ​​test: how fast do you really surf? Here's how to find out

Long loading times when surfing or streaming films can have many causes. A speed test can show whether the problem is with the Internet connection.

But there are also provider-independent test programs that are sometimes even more reliable. The best known is probably the free app Speedtest from the developer Ookla (Android / iOS). The Federal Network Agency also has a test for broadband measurement on offer. You can carry out this free speed test either in the browser or with a desktop app - there is also an app for Android and iOS.

This is how a speed test works: upload, download and ping value

A speed test measures how quickly you can upload and download files with your Internet connection. A test upload or test download is carried out in order to calculate the exact speed. Test data are therefore sent to the server (upload) or downloaded from the server (download). A ping test is also often carried out. Here, the time span between the transmitted and immediately received data packet is measured in milliseconds - the lower the ping value, the better.

This test is possible with all kinds of Internet connections. The mobile internet can also be checked with this speed test. However, one should bear in mind that correspondingly large data packets are used for fast LTE or even 5G connections. This means that frequent speed tests can noticeably gnaw at the data volume. Some test providers also provide information about which services you can use well with your Internet speed.

How to do a speed test

Please note that you should measure your home Internet bandwidth with a LAN connection (i.e. it should be connected directly to the router via a network cable, not with a WLAN connection). Otherwise it cannot be ruled out that connection bottlenecks can also be traced back to the radio network. During the test you should keep all other applications closed so that the results are not falsified. It is also best to take several measurements on different days.

The test result always depends a little on the current server load on the other side in the Internet as well as on the network settings of your PC.

Before the measurement, the provider and the internet speed that has been contractually guaranteed for your connection must be selected. You can usually find both in your monthly statement.

The measurements of the Federal Network Agency

For several years now, the Federal Network Agency has published an annual report on its broadband measurement. The result of the latest report in April 2020: Only around 16 percent of users in the fixed network reached the agreed maximum speed or more. That was a slight increase compared to the previous measurement period, when this value was 12.0 percent.

Across all bandwidth classes and providers, 70.1 percent of users (2017/2018: 71.3 percent) should have downloaded at least half of the contractually agreed maximum data transfer rate.

According to the information, the agreed services were achieved even less frequently in mobile communications. Customers only achieved more than half of the agreed maximum speed in 16.1 percent of the measurements, and 1.5 percent of the measurements were more speed than agreed.
