How to improve the accuracy of the speed test

Ensure that you do not have any downloads or uploading taking place whilst you run the test. The less applications you have running on your PC/device the better. For an even more refined test, connect to your broadband router using a Ethernet cable. That way you will rule out any WiFi issues or interference and it will be an even more accurate reading.

What is the Ping result?

The ping response tells you how fast you get a response back from a web server. Ping is measured in milliseconds (ms). This is your connection’s reaction time. The lower the number the better the connection. Anything around 6ms is good.

What is Jitter?

Jitter is a delay during the transfer of data. This is the delay between when a signal is transmitted and when it is received. Jitter can be caused by a number of factors such as network congestion, signal interference and collisions. Jitter is measured in milliseconds. All internet connections experience a level of jitter and it is most visible and problematic for real-time applications such as online gaming, streaming and voice communications (e.g Skype). For optimal performance, jitter must not be over 15 milliseconds maximum or else there will be an impact on performance.

What is the download speed?

Download speed is measured in megabits per second (Mbps). This is a measure of how quick your broadband connection pulls data from online internet servers such as displaying web pages, watching videos and downloading files. Your internet download speed result will be higher than upload speed because the majority of internet activity consists more of downloading than uploading (e.g. web servers sending the content of web pages to your computer/device screen). The data is downloaded so that it can be displayed on your internet browser. Difference between download & Upload speed.

What is the Upload speed?

The upload speed is how quick your internet broadband connection sends data up to web servers. When you click a link on a web page your computer ‘uploads’ a small data signal (also know as a packet) to the website telling it that you have clicked on a link. The web page then reacts by displaying the content of the link clicked. Displaying the content of the web page uses your ‘download’ bandwidth to send the data (i.e text, image, videos, etc) of the new page to your screen hence why download bandwidth is (should) always be higher than upload. Other examples of uploading are sending files, emails, video chat or messaging.

Frequently Asked Questions

Why should I test my internet speed?

If your internet connection is not working as expected or you are suffering intermittent disconnections or performance issues, testing your connection is the first step to identify and troubleshoot the problem. You can use the speed test on this site to make sure that you are not being short changed by your Internet Service Provider (ISP)

Why do Speed Tests results vary?

Speed test results from one or several different online speed tests can vary due to a number of reasons such as:
– Contention on your Internet Service Provider’s network
– Load on your broadband connection at the time of the speed test
– Difference on where the speed test servers are located
– Different test methods between the online speed test providers

Why are the results on my Phone different to the test from my PC?

The speed test is a real time measurement of your broadband speed. Speed test taken within minutes of each other may differ.

Variations in Wi-Fi and cellular radio quality and MIMO stream handling quality between devices can cause varying results between a phone, tablet and PC.

What can I do if my Speed Test results are slow?

You have two options if your speed test results are not what you expect.

Check that other users on your broadband are not streaming or downloading huge files. Any ‘above average’ utilisation on your broadband will affect your speed test results. We recommend that you reboot your PC and broadband router and run a clean test.
If you are continually suffering from slow broadband performance from your provider, it may be time to find an alternative broadband provider.

Which broadband speed test is the best?

Last Updated on August 2020 by

Why are my speed test results lower than I expected?

Last Updated on August 2020 by

There are numerous reasons why your Speed test results may be slower than you expected. To ensure that your results are accurate make sure you;

Use a wired Ethernet connection instead of wireless
Stop or close any programs working in the back ground
Ensure that your internet connection is not being saturated by others in the household e.g downloads, streaming, internet calls, etc.
Restart your broadband route and the re-run the test

If the results are still the same it could be a fault of your broadband connection. Contact your supplier to check your connection.

Alternatively if you are aware that your connection is constantly unreliable and are looking to switch – check out these alternative providers.
