Remember - your broadband speed will vary depending on things like how far you are from our equipment and how many other people are using the internet at the same time. So the speed of your plan is the maximum possible speed - not a guaranteed speed.

Why does broadband speed vary?

The speed listed on broadband plans is the maximum speed that can be obtained. However there are heaps of reasons why your connection speed may be less than the maximum.

Factors that affect speed outside your home or office

  • Internet environment: It may be faster to download from a NZ site than an overseas site.
  • Internet traffic: The more people accessing the Internet the slower the speed e.g. between 4pm to midnight.
  • Distance from your local telephone exchange: The further away you are from the exchange the slower the connection.

Factors that affect speed inside your home or office

  • Computer set up: Your computer's operating system, available memory (RAM) and set up can impact on connection speed.
  • Modem types and connection: An Ethernet or wireless connection is generally faster than a USB connection.
  • Wiring in your house or office: The length and quality of wiring in your house or office. Speed will also be affected if there's a fault on your phone line.
  • Sharing your connection: If more than one person is using the same connection in your house or office speeds may slow down.
  • The applications on your computer: Some applications may use all the spare bandwidth or memory on your computer. Test this by turning off each application you're using and checking your speed again. Make sure you turn off any anti-virus software before you do this.
  • Viruses and spyware on your computer: Your computer may have been infected by viruses or other programs like Spyware.

How can I improve my speed?

Since there so many things that can affect connection speed there is no guarantee it can be improved. However these things may help:

  • Check your monthly usage: If you're on a capped data plan check to see whether your connection has been slowed to 64kbps. Simply Sign in to My Vodafone and select check usage.
  • Use broadband filters: Check that all your jack points and devices using a phone line (such as a burglar alarm) have broadband filters installed.  Empty jack points won't need a filter.
  • Get a splitter installed: This will separate your broadband connection from your phone line.
  • Switch to an Ethernet or Wireless modem: They generally connect faster than a USB modem.
  • Don't use long phone extension cords: Long extension cords slow the broadband speed on your phone line.  Where possible, plug your modem into the main phone jack point.
  • Scan your computer for spyware, adware and viruses:  We recommend you run regular scans of your computer with up-to-date anti-virus or anti-spyware software.
  • Use modern equipment and software: Use the most up-to-date computer and operating system possible.

Why is broadband speed so important?

The faster the download speed the faster you'll be able to open websites & pictures, play videos and receive emails with large attachments.
The faster the upload speed the faster you'll be able to upload photos to a website and send large files to other people.

What speeds will I get with a broadband plan?

All our plans are on maximum download and upload speeds!
