We work hard to ensure our broadband service has market speeds and consistency throughout the day. There a range of factors that can affect the connection speed you experience, learn more below and test your connection.
Test your broadband connection speed
Measure the upload and download speeds of your internet connection by taking the simple test.
For the best results, close all applications and windows, and, if you have a wireless router, make sure you are connected via an ethernet cable or wired connection.
Please choose your nearest location
What does this test measure?
The speed test measures the connectivity from your computer to Spark's core network. It doesn't test the speed between your computer and overseas websites or servers. Speed can be affected by factors including computer processing power and how busy your network is.
Get the most out of your current ADSL broadband connection
There are a number of things you can do to enhance the quality and speed of your home broadband connection:
Use the best quality wired (ethernet) or wireless modem for your ADSL broadband. You'll benefit from having a new device that contains better technology and that will generally connect faster than a USB modem. If you need a quality ADSL modem our very popular Spark wireless modem offers excellent wireless coverage for a great price.
If you have Spark's ADSL Broadband, check that broadband filters (also known as 'line filters') are installed on all your phone jack points that have phones, answerphones, fax machines, health alarms, etc, connected. Do you have a home alarm? If so then you could invest in getting a splitter (like a master filter) installed that effectively splits the broadband connection from the alarm system so that they don’t interfere with each other. Splitters can also improve your broadband speeds if you have more than 5 phone jackpoints in your house, so talk to our broadband specialists to get one installed. We also recommend you do an isolation test, where you disconnect all devices that are connected to the phone line throughout your house, and try moving the ADSL Modem to different jackpoints. If there is a difference in speeds then a splitter would also be recommended.
Using long or poor quality extension cords between your ADSL modem and its jack point can slow the speed on your phone line. Also check to make sure there’s been no furniture on the cord or people walking across it, and that no pets have nibbled on it! Ideally your ADSL modem should have a single short cable connecting it to the jackpoint (or filter).
Ensuring that home appliances like your TV, stereo, lighting, microwave, fridge and washing machine are at least 2 metres away from your wireless modem will reduce interference for your wireless devices.
You can check your connection speed at any time with our easy broadband speed test on this page.
Use the most up-to-date operating system on all your PC, laptop and tablet devices and use a security program that can scan your computer for adware and viruses that can affect your connection speed. Spark broadband customers receive free McAfee security software to download as part of our Premium Services.
Why broadband speed can vary
Your connection speed determines how quickly you can access content over the internet. Find out more by watching our short video.
Broadband speeds inside your home
There are a number of ways your home connection can be affected. Watch our video for some simple tips on how to improve your home connection.
With Ultra Fibre® 30, the service has the ability to deliver Fibre speeds up to 30mbps downstream and 10mbps upstream. Ultra Fibre 100 has the ability to deliver Fibre speeds up to 100mbps downstream and 50mbps upstream. However, upstream and downstream speeds are based on a theoretical maximum, and actual speeds will be affected by various factors including NZ and overseas networks, your modem and computer technology, internal home wiring and other environmental factors
The Fibre network, like broadband over ADSL, is shared with other properties within your Local Fibre Company (LFC) and Retail Service Provider (RSP) networks. Speeds will vary depending on how many people are on the network at the same time both in your house and in general on the Internet. This is also true for overseas networks when accessing content, such as websites or streaming video.
Content such as web pages and videos are stored on ‘content servers’ so you can access them via your internet connection. Content servers within New Zealand and overseas can reduce the rate (bandwidth) at which you access their content (for instance, when they are very busy), this affects the time it takes to download content and thus your speed.
If connecting via WiFi the connection can be impacted by environmental factors like other wireless devices in the house (such as mobile or digital phones) and even your neighbours’ Wi-Fi connection.
The speed capacity of the devices you are connecting with may be a limitation, for instance the age of their WiFi adapter Other hardware and software components can also limit the processing of bandwidth and thus your speed. The most reliable connection and faster speeds will be achieved by connecting devices directly to your modem via high-speed Ethernet wiring instead of using Wi-Fi. For example, a Cat5e is a high-quality copper cable, designed to deliver Ethernet standard services over short distances at speeds of up to 1Gbps.
Speeds will vary by property* but an average NZ household, could see downstream speeds up to 3x faster and upstream speeds as much as 9x faster than a standard ADSL connection. As with ADSL though, speeds vary based on how far you are from the nearest cabinet or exchange, the quality of the copper wire up to and inside your house and other factors. Technically the service can support speed between 15 - 70Mbps downstream and 5-10Mbps upstream.
*VDSL speeds can vary widely depending on a property’s location, the condition of its copper wiring, how busy the local copper network is at any given time of day and other factors.
