Bredbandskollen is using multiple servers to measure against in Sweden and one in Norway. You can manually select which one to use in "Advanced measure". If you don't make any choice we will select the closest server (closest from a networking perspective).

If you get a test result you are not happy with or if you experience other issues you should start by contacting your ISP.

If this does not help you may contact Telekområdgivarna who are impartial and provides advisory services free of charge to consumers.

If you measure against the server we call Anycast(Global), you will always be connected to the server that is nearest to you in terms of network proximity. Currently, in the web measurement, we cannot show you which server you were measuring against, and it always displays Anycast(Global) as the server. In the future, you will be able to see which server you were measuring against.

If you measure against the server we call Anycast(Global), you will always end up on the server that is nearest to you in terms of network proximity. It's not always the server that is geographically closest to you but depends on how your internet service provider's network is structured. For example, if you live in Bollnäs, the test server in Sundsvall is closest geographically, but it might be that your internet provider still routes all traffic via Stockholm, and then the measurement is done against the server in Stockholm.

If you still want to test against the geographically nearest server, you can choose the server yourself under 'Advanced measurement'.

There are two links, “Download as CSV” and “Download as JSON,” where your previous measurements are displayed.

By clicking “Download as CSV,” you will receive a file containing all your measurements in a format that can be easily imported into Excel and other programs.

By clicking “Download as JSON,” you will receive a file containing all your measurements in a format that is more complex but often used by more advanced programs.

If you have problems running Bredbandskollen, please contact us using the contact form you can find on the web page after you have completed a test. Please specify which version of operating system and which web browser you are using.

If running the app we need to know which mobile device model you are using and what kind of subscription you have.

Describe your problem as thorough as possible. That will help us to help you.

Bredbandskollen does not recommend any specific ISP. There are other independent services assisting you, i.e. bredbandsval.se and bredband.se.

To measure connection speed in an environment that is missing a web browser, for example, in a server, you can use our command line interface bbk_cli, which is available for some of the most common operating systems. Read more here Bredbandskollen CLI.

When performing a test from a mobile you need to make sure that you are using the cellular network and not your local wifi network. Temporarily disable the wifi in your phones settings during the measurement. Don't forget to enable the wifi again after the test.

We have developed apps for both iOS and Android. You may find them in the app store on your phone.

To make the result independent of what OS you are using we have developed the app as a web app.

Wireless internet is practical but can provide a slower connection than if you use a cable. Make sure that you have a modern router and place it centrally in your home. Try turning the router in different directions and, if possible, change the direction of the antennas during measurements.

The speed of mobile surfing can vary depending on whether you are surfing indoors, outdoors, or in a car. If you are in the basement, you may get a lower speed than if you are sitting in a room with windows. Other factors that may play a part are the number of users that are surfing in the same area and the distance to base stations.

When you use multiple machines (computer, tablet, mobile phone, broadband tv) on the same connection it is not surprising if some of them have worse speed. All share the same connection, therefore results are not as good as with just one computer.

Check that you have the latest version of your web browser and uninstall any plugins that might affect the speed. Also check that you have installed the latest updates for your operating system on your computer, tablet or smart phone.

Try temporarily disabling any anti-virus software and internal firewalls in your computer. Some browsers are more affected by firewalls and antivirus programs, try using another browser on the same computer.

We measure how quickly your client can download and upload data to and from our measurement server. The factor that limits the speed is the slowest link in the chain.

Wired networks (ethernet) today range in speed from 10 to 10,000 Mbps. For new computers and routers, 1,000 Mbps is standard.

WiFi comes in various standards, with the newest ones capable (under ideal conditions) of achieving more than 1,000 Mbps. In practice, new computers and routers typically have speeds between 50 and 1,000 Mbps, depending on the WiFi technology they use and how close you are to your router. Often, mobile phones achieve higher speeds on WiFi networks than computers do.

If you have an internet connection of 10 Mbps, the results are usually not affected whether you measure over WiFi or ethernet. If you have a connection of 1,000 Mbps, you will most likely get better results over ethernet than over WiFi.

With a stable connection, the test consumes approximately half the amount in megabyte as the measured bandwidth in Mbps. E.g. if the measured bandwidth was 20 Mbps the test used approximately 10 MB of data. With a less stable connection as much as 20 MB may be used in the test.

N.B. if you are measuring over 5G you may reach speeds above 1000 Mbps. The data transferred will then exceed 1000 MB which will impact your available data volume if you don't have a subscription with unlimited data.

If you have access to IPv6 you can start the test over IPv6 by selecting it in the "Advanced measure" section.

Please note that you will receive an error message if you enable IPv6 and run the test without having access to IPv6.

When you have performed a test with Bredbandskollen you will in addition to the measurement get a grading of how well your internet connection performs relative the speed your Internet Service Provider (ISP) has committed to. To get a pass for the measurement it needs to be over the lower limit stated in the subscription from your ISP. An acceptable result is 80-85% of the maximum committed bandwidth.

If we can't automatically get the speed of your subscription from your ISP you may manually enter data about it to be able to evaluate it.

Bredbandskollen is a free tool for internet users and is run by The Swedish Internet Foundation which is an independent, private foundation that works for the positive development of the internet. Read more here.

Measurements in Bredbandskollen are performed by sending random data between your internet browser and the test server over the web sockets protocol (ws://). The available bandwidth is calculated by dividing the amount of transmitted data by the duration of the test in seconds. A measurement takes 20 seconds (both download and upload).

If you encounter any problems during the test you might get a result that is lower than the actual bandwidth.

We have test servers located in Sundsvall, Stockholm, Göteborg, Malmö and Oslo. The selection of which test server your test will be performed against is automatically done to the closest one from a network perspective.

You can manually select a test server in the "Advanced measure" section.

Some Internet Service Providers provides us with characteristics about your internet connection and we share the result of your test with them. If you get an automatic evaluation, it implies that this is the case.

Authorities, regions and municipalities may purchase anonymised measurement data from Bredbandskollen. The purpose is that they will use this data to make mobile operators improve their coverage and speed where our data indicates that it is necessary.

Upon request from research institutes, studying the development of internet infrastructure, we share anonymized measurement data.

All measurements done from a mobile phone using the app are saved in a database. The results are displayed in Surfkartan which is a map that's supposed to give an overview of the actual bandwidth in the cellular networks.

You can choose yourself if you like to share your location with us, in the privacy settings in your mobile device. You will of course still be able to run the test no matter what option you select.

The map shows tiles with average values for the mobile measurements made in each tile. When you zoom in our out, the sizes of the tiles changes and thus the number of measurements included in each tile. Hovering a tile (or tapping if you’re on a touch screen) displays the average download, upload, response time and number of measurements in the tile.

By adjusting the selections below the map, you can choose which value (Download, Upload, Response Time, Number) the color of the tiles should be based on. You can also filter the results by operator, time period and network technology to customize the display of the measurements. In the address bar, you can search for a specific address to quickly find and display that location directly on the map.

The map is updated once a day, which means that it can take up to 24 hours before your measurement appears on the map.

Measurements in Bredbandskollen are carried out by sending messages consisting of meaningless data between the browser and the measurement server via websockets (the ws:// protocol). The speed is then calculated by dividing the amount of data sent by the number of seconds the measurement lasted. The measurement lasts for 20 seconds (10 seconds for the uplink test and 10 seconds for the downlink test). If you happen to have a temporary problem when the measurement is taking place, your actual speed may be higher than what Bredbandskollen shows.

The measurement in Sweden is done against the network-wise nearest of our measurement servers (which are located in Gothenburg, Malmö, Oslo, Stockholm, and Sundsvall).

You can choose to use a different measurement server than the one Bredbandskollen has chosen for you, which can be done in the Advanced measurement menu.

Yes, due to the use of javascript in bredbandskollen.se we can't use encrypted communication (https) between the web browser and server. However, no sensitive information are transmitted during the test as we are using random data to transmit.

If you allow the app to use your location, your position will be stored in the database. The accuracy of the position may vary between a few meters and a few hundred meters. If you do not want your location stored, you can choose to not allow this in the settings on your phone. You can then continue to do the measurement on the app, but you will not be able to see other measurements near you.

If you have a question not listed here, you may send it in an email to support@bredbandskollen.se and we will add it with an answer here.

If you get a measurement result that you are not satisfied with, it is important that you contact your operator directly. Alternatively, you can contact Telecom Advice (Telekområdgivarna) that give impartial and free help to consumers.
