Key points 

Speed test

A simple speed test will allow you to check for Wi-Fi coverage issues by comparing your speed when connected via an Ethernet cable and also via Wi-Fi at different points throughout your home.

To ensure you're getting the most accurate results, try to conduct your tests at a time when your connection won't be impacted by the use of other devices, such as streaming video on your television.

How to conduct a speed test

Your results

Minimal difference in the recorded speeds:

If the speeds you recorded while connected by Ethernet, are similar to the speeds you recorded while connected by Wi-Fi, your Wi-Fi network coverage should be adequate and capable of providing consistent speeds.

If you conducted the test over Wi-Fi only, and the speeds you recorded at various locations in your home are similar to the speed you recorded while standing next to your modem, this too is an indication that your Wi-Fi network coverage should be adequate. 

Note: If you are still unhappy with your speed it could be related to the type of plan you are on, or potentially an issue that needs to be investigated. Please contact your phone and internet provider.

Significant difference in the recorded speeds:

If your recorded speed over Ethernet is significantly faster than those recorded over Wi-Fi, or if some locations in your home are faster than others, this is an indication there is room for improvement with your existing home Wi-Fi coverage. Work through the following steps to optimise your connection.

Note: that the speed test result is influenced by a range of other factors, not just your Wi-Fi connection such as; how many other devices are using the connection at the same time, your broadband speed plan, wireless interference, broadband congestion (typically higher during peak times 7-11pm)

Key points

Where you place your modem matters

The physical objects between your device (laptop, phone, tablet) and your modem can play a big part in the quality of your Wi-Fi signal. Some materials that can significantly reduce your Wi-Fi signal include:

Thick walls – Brick, cement walls.
Metal panels – Cupboard doors, mirrors, shelves.
Appliances – Refrigerators, televisions, microwaves.

Tips on modem placement:

• Try to place your modem in a raised and central area (never on the floor).
• Avoid putting your modem behind the television or tucked away in a cupboard.
• Connect fixed devices, like your television, directly to your modem with an Ethernet cable.
• Keep in mind, the smaller the distance from the modem, the better the signal and faster the speed.

If you have a medical alarm connected to your modem, speak to your provider before moving your device as this may affect your alarm connectivity. 

Check for wireless interference

Wi-Fi signals from other networks and devices (like those from your neighbours), as well as non-Wi-Fi sources, have potential to overlap and cause wireless interferences that can slow down the speeds you receive. While this type of interference can often be inconsistent and difficult to detect, there are some known causes you can try to avoid:

• Microwave ovens
• Bluetooth devices
• Wireless security systems
• Cordless phones

To help minimise any potential wireless interference, try connecting to the 5Gz band of your modem whenever possible, or move your devices and modem away from known sources of interference.

Choose the optimal Wi-Fi band

The Wi-Fi band you connect to can have a big effect on the strength of your signal. When connecting to your modem for the first time you may see two networks on your device:

• [MyNetwork]
• [MyNetwork]_5G

These networks signify that your modem supports two Wi-Fi bands, which each operate on separate frequencies (2.4GHz and 5GHz).

When connecting to your Wi-Fi network, it’s best to choose the _5G network first, assuming your device recognises this as an option. Some newer modems will automatically select the best network for you. There are a handful of notable differences between each frequency:

Key points

Check your modem

Modem features to look out for:

We recommend that you do some research online and find the solution that works best for you, within your budget. Like most things in life you generally ‘get what you pay for’. As such usually the more expensive devices will perform better as they have higher quality components, more antennas, and a better build quality.

For more information about which device is right for you, please speak to your phone and internet provider.

Upgrade your devices

Older devices tend to have fewer internal antennas and support older Wi-Fi standards, which are slower. If you’re experiencing poor Wi-Fi connections using older devices, you may want to check the Wi-Fi performance using a newer device from the same location. This will help you work out if your older device may be the cause of any issues. 

Key points

Expand your Wi-Fi coverage

Wi-Fi extenders and mesh devices

Wi-Fi extenders and Wi-Fi mesh devices can broaden Wi-Fi coverage throughout your entire home, while also reducing the instances of dropouts and slow speeds due to limited Wi-Fi coverage. There are however some differences between the two:

Extenders

Wi-Fi extenders work with your existing modem to boost the Wi-Fi signal to additional areas of your home, but typically don’t provide as much Wi-Fi coverage as mesh devices. They may also broadcast a new network name, meaning you will have to select a new network on your device to connect to the extender.

Mesh

Wi-Fi mesh devices replace the Wi-Fi connection from your existing modem and generally provide more complete coverage. They also automatically connect your portable device to the strongest/closest Wi-Fi mesh node. Wi-Fi mesh systems are however more expensive than Wi-Fi extenders. 

Key points

Examine your internal wiring

Consider network cabling

Where practical, you could consider using physical network cabling from your modem to connect your fixed devices such as televisions, desktop computers and game consoles for best performance.

• What devices do you use? Make a list of all your internet connected devices and services.
• Where do you need to use them? Mark where your devices and services need to be located on your floor plan. 

Contact a registered cabler

A registered cabler can inspect your home and make changes that can improve your internal wiring. Here are some topics to discuss with your technician:

• Ask your registered cabler to connect your modem to the first telephone socket, it's usually located near your front door. If you're not happy with where your first socket is located, your technician might be able to re-cable to your preferred location for a first socket. For more technical information about this, refer to the Communications Alliance guide G649.
