Speed Test Guide

Why run speed tests?

A speed test is a useful diagnostic tool to identify if there is a problem with the service, and to measure the severity of impact.

How do I run a speed test?

There are some steps you should take first to ensure the test is accurate.

Step 1: Turn off all other internet use. You may receive a falsely low result if your service is being used simultaneously by other applications. You want a true measurement of the speed the service is achieving, not what’s left after everything else uses it. Alert other family members not to use the internet for the 60 seconds or so it takes to run the test. If possible, turn off other devices or disconnect them from the connection

Step 2: If possible, do the speed test over an ethernet cable. This would typically mean using a device like a desktop or laptop computer; even some Smart TVs have the capability. What you want to measure is the speed of the service that’s being delivered to your premises. If that’s fine, the next step would be to test over WiFi for comparison. The resolution for your speed problem is going to be different if it’s a WiFi issue versus a slow connection, so you’ll need to know what you are dealing with to get to the correct resolution.

But then it’s as simple as visiting speed.dcsi.net.au and clicking the big GO button.

What do my results mean?

Download and upload measure how quickly information is transmitted to and from you. The higher the number, the faster the connection. Your maximum speed will be limited by things like your plan and your infrastructure, so there’s no one right answer on what a “good” or “bad” speed may be. You’ll need to refer to your plan’s theoretical maximum speeds, which usually appears on your invoice. If you need help with this, just ask.

Ping measures your connection’s reaction time – how quickly it receives a response. This is where you want to see a low number – the lower, the better. Jitter is a measurement of variability in ping times.

What can cause slow speeds?

Many things. There are so many individual systems and devices involved in the delivery of your internet connection. Your speed may be slow due to a fault in the infrastructure connected to your house, or a failing router. Perhaps the connection is performing at its best, but the limits of your plan are too restrictive for your household. These are just some of the possibilities. We use speed tests results as one element in troubleshooting to assist us in accurately pinpointing the source of your slow speeds.

What do I do with the results?

You can use it for your own peace of mind, to establish that your connection is performing as it should. Sometimes it’s a fast answer to the question “Is it this site that’s slow, or is it my connection?”.

If you report an issue with your service, DCSI may ask you to run speed tests so we can gather information to establish the impact on your service. This information can be very important particularly if there is an issue that needs to be logged with a wholesale provider, or to determine if technicians are needed to go onsite.

How often should I run speed tests?

Speed tests are quick, simple and free, and can be done at any time. If you are a DCSI customer, your speed test history is automatically logged and can be reviewed if any problems arise. Having a history of tests that show the performance of the connection over time can be a really useful tool. You should run a speed test as often as you want to, even when you aren’t experiencing problems.
