Internet Connection Speed Test

For VoIP to work correctly, you must have a strong and consistent Internet connection.

The quality of VoIP calls depends on the speed of your internet connection. The faster your Internet connection is, the better your calls will sound.

Our speed test is currently undergoing maintenance. In the mean time, please use the SourceForge HTML5 speed test.

Our internet speed test is specially designed to test your system for VoIP phone calls. It checks your Internet connection's quality and speed and provides you with an easy-to-understand report afterward. You can also submit your test to a testing company to further diagnose any problems you may detect with your Internet connection.

The purpose of this speed test is to analyze an Internet connection and check the packet loss, buffer bloat, download speed, jitter, upload speed and latency. Once the test has finished running, the results will reveal what the tested Internet connection can handle.

The result will also contain additional information about the tested connection. Since this is an HTML5 speed test, it doesn’t require Java or Flash, and it’s compatible with virtually all devices, which includes smartphones, tablets and desktop computers. By pressing the start button, users can begin the test.

How the HTML5 Speed Test Works

Once the speed test has been activated, it will analyze the user’s Internet connection. It will test the base speed of the connection and examine several additional factors. Some of the extra factors that it examines are packet loss, jitter, ping, buffer bloat, download speed and upload speed.

The purpose of the test is to give users an idea concerning what types of services are supported by their Internet connection. The test will check an Internet connection and determine if it’s suitable for gaming, YouTube, live video streaming, Netflix and VoIP. It will also test the connection for compatibility with a number of other services.

Many other Internet connection tests require the user to have Java or Flash, but this test doesn’t have these requirements. Since it uses HTML5, the test offers greater compatibility than many of the alternatives because HTML5 is universally compatible with most devices.

Check a Connection for VoIP Compatibility

Many users want to know if their Internet connection can handle VoIP services. To find the answer to this question, they need to run the test and check the speed of their Internet connection. If the user receives a good result, then the connection should be able to handle VoIP services. If the user receives a poor result, then there are several steps to take.

What to Do After Receiving a Poor Result

  • First, the user should check to see how many devices are connected to their network. If several devices are connected, each device must compete harder for bandwidth. This problem is called network congestion, and it’s a problem that many networks have. A better result can be obtained when there are fewer devices connected to the network.
  • The second step involves checking the wiring. Old wiring and loose connection can cause the HTML5 speed test to produce a poor result.
  • The third step consists of updating hardware. If a network is running on outdated routers or modems, it can significantly reduce the connection speed and cause the test to produce a poor result.

The purpose of this test is to give the user detailed results. Every user should know the frequency of data packets, quality of connection and speed of their Internet connection. The test is set up to help users understand how their Internet connection functions. It’s also designed to tell users if their connection can handle VoIP services.

The Characteristics of a Quality Connection

It’s very important for users to understand the results of the speed test. It’s the only way to know if their Internet connection can handle VoIP services. The results from the HTML5 speed test are based on how data flows through a user’s Internet connection. The flow of data is especially important when a user is considering getting a VoIP service.

Since a VoIP service relies exclusively on the user’s Internet connection, it’s very important for the connection to be solid. The VoIP service uses the connection to receive, compile, transfer and send data packets, which are converted into usable audio. Users need to decide what type of VoIP solution they need. The two major options are residential and business VoIP.

Business VoIP

Users who’re considering getting business VoIP need to consider how their bandwidth is distributed. If there are several devices on the network that are competing for bandwidth, the overall Internet connection will be much slower.

When many employees are using the same network, the bandwidth is distributed among several devices, which can reduce the speed for each individual device.

Residential VoIP

When used in a home, a residential VoIP connection is distributed among several different home devices. The connection speed is shared for tablets, smartphones, video streaming services, downloads and gaming. These are some of the common ways a home Internet connection is used.

When many devices are using an Internet connection at the same time, it reduces the speed for each individual device. There are also other factors that can reduce the quality of the connection. Many Internet Service Providers stream data based on how a home Internet connection is being used.

How to Understand the Test Results

Although they might sound complicated, test results aren’t terribly difficult for users to interpret. Once the speed test has finished running, the results of the test will be presented in several formats.

The problem is that many users don’t understand what the test results actually mean. Below, users can find out what the results actually mean.

Packet Loss

This part of the Internet speed test measures the number of data packets that actually make it to the destination that they were sent to. Ideally, the results from the test should reveal a packet loss result of zero. However, user shouldn’t be frightened if the test reveals slight packet loss.

Buffer Bloat

The test results for buffer bloat measure an Internet connection’s latency. The HTML5 test examines the Internet connection when it’s placed under stress and checks to see how it performs. In most cases, this part of the test consists of a bandwidth test, which maximizes the Internet connection.

Upload Speed

The upload speed is very easy to understand. It reveals how many bits per second a computer can upload using the Internet. Upload speeds are usually slower than download speeds.

Download Speed

The download speed is the exact opposite of the upload speed. This part of the test measures how many bits per second a computer can download from the Internet.


The jitter results are calculated based on consecutive latency test results. Ideally, users should hope for a jitter result of zero, but it can still be a decent result if it’s close to zero.

Ping and Latency

The latency result tells the user how long it takes for a packet to be sent to a remote computer and back to the host computer.

How to Improve an Internet Connection

To make sure VoIP works properly, users need to make sure they have a solid Internet connection. For optimal results, the connection should be fast and reliable. If a user has a bad connection, there are several ways to improve their Internet connection. The first step consists of running the speed test.

If the test displays a speed that is suitable for VoIP, then there is no need to improve the connection. In some cases, it’s not the actual connection that causes a poor test result. The ISP could be responsible for a poor connection, so users can call their ISP and ask about the connection.

Users who get a poor test results should find out how many devices are competing for bandwidth on their network. It’s a good idea to make a list of the computers, tablets and smartphones that are sharing the connection. Users should avoid using a VoIP adapter with Wi-Fi because the speed is likely to be much slower than a hardwire connection.

For the best results, users should plug a VoIP adapter directly into the modem that was supplied by the ISP. It’s also a good idea to do this when running the speed test because it will eliminate outside interference. If a user plugs everything directly into the ISP modem and receives poor test results, there is a good chance that the problem is being caused by the ISP.

The next step to take involves calling the ISP support and finding out if the connection is capable of handling a VoIP service. To check for business or home network issues, users should plug their computer into the router, which should be directly connected to the ISP modem.

After the computer is connected, the user should run the speed test. If good results are obtained by doing this, the router and ISP can be ruled out as potential causes of the poor test results. This process can be repeated for all upstream devices.

By running another speed test with each device that is connected to the network, the user can pinpoint the cause of the poor test results. In many cases, a poor connection can be fixed by replacing a piece of hardware or Ethernet cable.
