What can I do to improve my WiFi?

If you want the fastest and most reliable internet throughout your home or office Ethernet is the way to go. However in the real world we know that you can’t run cables all over your house and that’s where Wi-Fi will help you get all your devices online.

Wi-Fi uses radio waves to transmit information over a specific area. Because your data is transmitted over radio waves they can be more sensitive to interference and obstacles which means that your internet connection could possibly be slower and less reliable,

Here we have listed a few important things to consider when setting up Wi-Fi in your property, to make sure you get the most out of your Wi-Fi modem.


Where you place you Wi-Fi modem in your home is one of the most important things to consider when setting up your home internet connection as the location of your modem can impact the overall quality of your Wi-Fi connection.


The ideal location of a Wi-Fi modem is as close to the centre of your home as possible, in an open area (so not inside a cupboard) away from other electronics.  Also if possible keep your modem as high as possible as Wi-Fi signals spread downwards, if you have your modem on a low shelf or on the floor you won’t have the best experience.


There are several things that can reduce, reflect, or even block Wi-Fi signals throughout your home, these include:


  • Fish tanks (and other items filled with a lot of water like a swimming pool or large water features)
  • Metal fencing, doors,  and/or roofing (e.g. tin roofs, sheds, )
  • Brick, concrete, load bearing, and metal lined walls
  • Insulated thick glass
  • Mirrors
  • Stainless steel / metal Appliances, furniture,  and fittings (fridges, dishwashers, steel  counters)

If there are any of the above things near where you have installed your Wi-Fi modem they could be causing parts of your home to be missing out on Wi-Fi or slowing down your data connection considerably.


Wi-Fi can weaken the further it has to travel especially if the signal has to travel through multiple walls. For the best experience with Wi-Fi make sure your modem is installed as close as possible to where you will be using your internet the most.

If it’s not possible to install it in the area you use it the most, take a look at possibly installing a power line adaptor or Wi-Fi Range receiver.


What does your Modem and your Microwave have in common?  More than you might think, both devices transmit waves around the frequency of 2.4 Ghz

What does that mean for my internet connection? 

It means that if your modem is near your microwave, the microwave which has much stronger waves will cause your Wi-Fi connection to slow down or drop out completely when the microwave is in use.

It’s not just microwaves there are many electrical appliances that can interfere with your modem.   Cordless phones, Baby Monitors, TV’s, and speaker systems can also operate on the same frequency.

What can I do to fix this?

If it’s possible make sure your modem is installed as far away from your microwave (or other appliances) as possible, we recommend at least 5 metres.

Also if you live in close proximity to your neighbours make sure your modem is centrally placed within your property to avoid possible interference from your neighbours electrical equipment.

If moving your modem is not possible you might need to look at at alternative solutions to help improve your Wi-Fi experience.

Otherwise make sure you have made your microwave popcorn before you settle in on the couch with Netflix.


If you live in close proximity to your neighbours, their Wi-Fi networks may be interfering with yours and causing the signal to weaken.  Basically this means if you and your neighbours are on the same Wi-Fi channel this could be slowing down your Wi-Fi experience. 

It’s really easy to change the Wi-Fi channels on our Optus Supplied Modems.

If you have a BYO modem you will need to refer to the manual that came with your modem or visit your modem manufacturer’s website.


If you share your internet connection with people who like to make video calls, play online games or stream TV at the same time the quality of your connection may diminish.

Wi-Fi is capable of handling many devices connected at the same time but the quality may decrease if numerous users are using data heavy applications at the same time.  Make sure that any devices that are using Wi-Fi are turned off when not in use.

You can check what devices are connected to your network by checking your modem settings

If you have tried the above things and the Wi-Fi is not reaching all the places in your property you need it to, or it’s not possible to move your modem to another part of your property there are some more technical solutions that can help improve your Wi-Fi network performance.


If you have your Wi-Fi modem installed in one part of your home, but the Wi-Fi signal doesn’t reach a particular part of your property, or the Wi-Fi isn’t as strong as you would like it to be. A Powerline adaptor could help improve your connection.

Powerline adaptors work by making use of the existing electrical wiring in the walls of your property. You plug in an adapter near where your modem is installed and connect the adapter to the modem via an Ethernet cable.  Next you plug in the second adapter in the room or the area where you need coverage.

The powerline adaptor will create a new data connection (both Ethernet and Wi-Fi) for the room/ area where the second adaptor is installed.

Powerline adaptors can be purchased easily from electronic stores and online.

Powerline Adaptors will only work on the same electrical circuit as the modem so if you have a large property or multiple electrical circuits it might not be a suitable solution.


A WiFi repeater or extender can be installed to extend the coverage of your Wi-Fi within your property. Wi-Fi repeaters work by taking your exisiting Wi-Fi, amplifying it and the transmitting the Wi-Fi to the far corners of your home or office, with the right placement you could even extend your signal into your backyard!

Wi-Fi range repeaters or extenders can be purchased from electronic stores and also online.
