Using Wi-Fi

Learn more about Wi-Fi and how to optimise yours to make the most of your Lightning Broadband service.

What is Wi-Fi?

Wi-Fi is a wireless networking technology that enables multiple devices to connect to the internet, using radio waves transmitted by the router. 


Wi-Fi Frequencies: Should I connect to 2.4 GHz or 5.0 GHz? 

A 2.4GHz Wi-Fi network will provide better coverage but less speed, while a 5.0 GHz Wi-Fi will provide better speed but can be negatively affected by distance from the router and physical barriers, such as walls!

We therefore recommend you use the 5.0 GHz network where possible as it allows devices to send and receive data faster and will provide a better experience. But if the two factors mentioned above may be having an impact on your connection, try the 2.4 GHz instead.

It is also worth noting the strongest and most reliable connection will always be achieved through an Ethernet cable. Wherever possible, try connecting more static devices such as a Smart TV or Desktop PC via cable to any of the router LAN/Ethernet ports. 

Where can I find my Wi-Fi password?

The password for your router network can be found on the back or bottom of the router itself.  

How do I change my Wi-Fi password? 

  • To change the password for your Wi-Fi network from the original one on the bottom of your device, you will need to log in to the router interface.

    The IP address for the interface should also be located on the bottom of the device, for example, which you would need to enter into the address bar of your browser. Both the username and password to access this site is likely to be admin. If you're struggling to log in to your router, please refer to our Router Set Up FAQ.
  • You can then change your password – but please remember to write the new password down and stick it to the bottom of the device so you don’t forget it!

My Wi-Fi is unstable or slow, how can I fix this?

  • First, check if you are experiencing the same issue across all your devices.
    • If you are experiencing the issue across multiple devices, next ensure they are connected to the appropriate network frequency, which may vary between devices (see above section on suitable frequencies).
    • If only one device is affected, it is unlikely to be the result of your Wi-Fi network, or connection, and more likely a hardware issue.
  • You can also check the router manufacturer website for a router firmware upgrade.
  • Confirm it is not an issue with your service by connecting your device directly to the wall port and testing for a connection – follow the port functionality test, the instructions for which are provided in our Troubleshooting FAQ.
  • If you wish to purchase a new router from Lightning Broadband, please contact our Customer Support Team on 03 9089 0515. We are also available to assist with further investigation if you are not able to identify the cause of the issue, or are not receiving service at the wall port.
