Why do the debit test ?

Your Internet connection is slow or you just want to know what your real connection speed is ? The debit test available on the Ariase site allows you to immediately measure the speed of your internet connection at home. This speedtest works whatever the technology used for your Internet connection, namely ADSL, optical fiber, cable or 4G and 5G.

The higher your downside, the more efficient your internet connection. It is the speed of your bandwidth that determines the time you need to download and send data on the Internet.

How a speed test works ?

A speedtest calculates in a few seconds the flow of your bandwidth whatever your type of ADSL, VDSL2, fiber optic, cable, satellite or hertziennes connection. This debit test available on the Ariase site allows you to measure the speed of your connection from an NPERF server. In France, NPERF has plsumers dozens of servers totaling more than 200 Gb/s of bandwidth.

The reception debit (Download) is measured thanks to the download of a file for 10 seconds, and vice versa to calculate the flow rate (Upload). This speed test also calculates latency time between your computer and the server.

How to optimize the flow test ?

In order to carry out the debit test in the best conditions, and to obtain a precise measurement of your connection speed, here are some tips to follow:

  1. Stop the current downloads on all your connected equipment,
  2. Turn off your TV decoder,
  3. Prefer a wired connection between your computer and the box (via an Ethernet cable rather than Wi-Fi),
  4. Close all tabs of your internet browser (except that of speedtest !)).

Test the quality of your Wi-Fi connection

More and more Internet users are connecting to their Wi-Fi Internet from a laptop, a smartphone, a tablet, or a console. To check if your wireless network is fast and efficient, test your flow in Wi-Fi mode. To make sure that the speed of your Wi-Fi network is consistent with the theoretical speed of your box subscription, compare the result with a wired speedtest.

Why my flow is slower when I do a Wi-Fi test ?

Your internet connection will always be faster if your speedtest is made from cable connected equipment rather than Wi-Fi. Because of disturbances, obstacles, distance or even radio signal losses, your wireless network is less efficient.

We advise Internet users to test their wired flow to precisely check the speed of their connection. By testing in Wi-Fi after on another equipment such as a smartphone or a laptop, you can assess the drop in internet flow due to your Wi-Fi connection.

What are the fiber, ADSL and 4G box flows ?

The speed of an internet connection depends both on the type of connection of your home, and your internet subscription:

  • Optical fiber : Between 300 Mb/s and 8 Gb/s for download and between 300 and 1 Gb/s in transfer.
  • ADSL / VDSL : between 1 and 95 Mb/s in Download and between 1 and 30 Mb/s in upload.
  • 4G Box : between 10 and 100 Mb/s in reception and between 5 and 50 Mb/s in broadcast.

What is megabits and gigabits ?

When we talk about megabits, this corresponds to the unit of measurement of your internet debit. More specifically, one megabit per second corresponds to a volume of data transmitted in a second. A megabit (Mbit) corresponds to 1000 kilobits. Be careful not to mix the “bits” and the “bytes” ! The byte is another unit of computer measurement made up of 8 bits.

A high speed connection with the high -performance ADSL allows you to download up to 20 Mbit/s, which therefore corresponds to 2.5 MB per second. Although the two are linked, we speak rather in Megabits per second to measure the flow, and more in megoacts to quantify a data volume.

What is latency ?

Latence is the deadline that flows between the departure of your computer information and its arrival on a web server, so this is the reaction speed of your Internet connection. So the more the response time is low, the more reactive your connection and therefore efficient.

Conversely, if the latency time is high, this can induce a gap between the actions you perform and their display on the screen. Latence also named Ping has an impact on online games or videoconferences.

How to improve your internet debit ?

To improve your internet speed at home, several solutions are available to you. First of all to boost your speed, it is necessary to limit as much as possible the connected uses simultaneously which slow down your connection. Indeed, a connection shared with many devices divides the bandwidth of the latter. Another good practice to adopt to improve your flow, you must favor connections via an Ethernet cable rather than the Wi-Fi network which generates more losses during transmission.

And if you cannot connect your equipment in wired, you can then change the WiFi channel on your box. Concretely, a WiFi modem uses a channel to distribute its signal. However, if a significant number of users in your sector are on the same channel, this negatively impacts your Internet speed.

You can therefore change this channel for a less congested frequency. To change the WiFi channel of your box, go directly to the configuration interface of your red model or contact your operator’s customer service.

Also think from time to time to reset your box so that the latter correctly performs its updates. An internet box that is not updated regularly can also cause loss of flow on your internet connection. To reset your internet modem, simply turn it off and turn it back a few seconds later.

And finally, to improve your internet debit, you can also consider a change of internet supplier. Take an eligibility test to obtain the list of internet box offers accessible in your accommodation. Another operator can offer you a higher speed. You can also be eligible for faster technology at another access provider such as fiber optics.

What speed do you need ?

Now essential in our daily lives, having a high -performance internet connection at home is essential. The higher your flow, the more fluid and faster your uses on the web will be. Discover our comparison of download times according to Internet connection speeds:

The main thing on the flow test

How to do a flow test ?

To test the speed of your connection, simply click the “Launch the test” button. The Speedtest then starts by checking your operator, your download debit, your rising debit (upload) and finally latency (ping) between your internet box and the server. When the debit test is launched, Ariase asks you to authorize your geolocation or not. By accepting geolocation, you contribute anonymously to enrich the map of measured speeds published by our partner Degroupttest.

What is the normal flow ?

A speed between 1 and 3 Mb/s is considered slow (low speed). A speed between 3 and 8 Mb/s is qualified as “medium speed”. In 2022, the value of 8 Mb/s corresponds to the threshold of a “broadband” connection. It takes a speed of at least 30 Mb/s to qualify an internet connection of “very high speed”. A normal flow should correspond to at least 70% of the commercial speed associated with your internet box. If you are connected to the fiber optics with a subscription up to 1 GB/s, you should have at least 700 Mb/s. If your speed is regularly measured at 100 Mb/s, your flow is not normal since it will then correspond to only 10% of the theoretical promise of your operator.

What is the best speed test ?

Ariase of course ! More seriously, Ariase has teamed up with NPERF, one of the world leaders in bandwidth measurement, to offer a reliable speed test. Based in Lyon, our partner NPERF constantly improves its sights to adapt to changes in the telecoms market (fiber optic, 5g. ) and add new test servers. The Ariase speed test is a great way to check the downstream, amount and latency rates of your internet connection.


Test the speed of your Internet connection

Test the speed of your Internet connection

The UFC-Que Choisir provides you with a speedtest. This free debit test allows, with a single click, to know the downhill flow, the upright rate (bandwidth) and the ping (or latency time) of your connection to the Internet. You will be able, in a few seconds, to have a precise idea of ​​the quality of your Internet connection.

How to interpret the results

Once the Speedtest has been carried out, three results are displayed:

The reception, or downward speed. This is the speed of transfer of network information to your computer, expressed in megabits per second (MB/S). The higher this speed, the faster the internet pages are displayed, the videos are launching and the files download. If you are connected in ADSL, a flow rate of at least 8 Mb/s is recommended. In fiber optics, it depends on the offer, but we can consider 200 Mb/s as satisfactory.

The sending, or amount amount. This is computer transfer speed to the network. Also expressed in megabits per second (MB/S), it has a direct impact on the time to send documents and files. In ADSL, it revolves around 1 or 2 Mb/s. In fiber optics FTTH (Fiber to the Home), it can, with certain offers, reach the speed of descending speeds, more than 200 Mb/s (it is lower in FTTB, or Fiber to the Building).

The ping, or latency. It corresponds to the deadline that the server’s upcoming information puts. It is expressed in milliseconds (MS). A weak ping (less than 50 ms) allows you to fully enjoy interactive services such as videoconference or online video games. Beyond 200 ms, a certain latency is likely to appear.
