What can I do at home to improve my broadband connection?

The way your home is set up for internet, and the way you use it, can often affect your speed. Here are some things that you can do to boost your connection.

Weak Wi-Fi signal?

The strength of your Wi-Fi signal can be affected by where you place your modem. Think about:

  1. Physical barriers like metal, wood, concrete walls or water – between the modem and your devices,
  2. Interference from other devices – like microwaves, cordless phones and baby monitors,
  3. The distance between the modem and your devices

Try this:

  • Place the modem in an area that avoids most metal (ductwork), floors, walls, pools, big fish tanks and if possible, in a space central to your devices.
  • Connect your device/s directly to the modem with an Ethernet cable – cable connections are almost always stronger.
  • There may be specific spots in your home or workplace where Wi-Fi just won’t reach, no matter where your modem is. The best way to extend your signal into areas like this is by installing a Wi-Fi Extender.
  • Discover the dead spots by creating a ‘heat map’ of your home that will show you where to put your modem, with the Telstra Home Dashboard™ App.

Too many devices or too much content? Your broadband is shared between all the connected devices in your home. The number of devices and how much data each is using can also affect the speed of the service.

Try this:

  • Switch off unnecessary or data-hungry devices that you’re not using
  • Switch off each device one at a time, and see if the connection speed increases noticeably. If it does, then check if that device is using a large amount of data, or has any viruses.

Virus or old age?

If your connection is slow on one device only, it may be infected with malware or a virus. Or your device might be too old to support higher speeds.

Try this:

  • Use a different and/ or newer device to perform the same action – and see if your connection improves
  • If it does, get your original device checked for malware or viruses. If it’s old, consider retiring it.

Faulty modem?

The quality and age of your modem will affect your connection. 

Try this:

  • Upgrade to one of the latest Telstra-branded modems. We recommend using a Telstra modem to maximise broadband performance. Contact us if you need a new Telstra-branded modem.

Bad internal wiring?

If the wiring in your house is faulty, it can interrupt the connection and slow your speed.

Try this:

Hire a qualified electrician or a Telstra technician to check and fix your wiring. Contact us to discuss this service.
