To boost your Telstra Wi-Fi, optimize modem placement (central, elevated, away from obstructions/appliances), reduce interference, reboot regularly, use the My Telstra app, or add a Telstra Smart Wi-Fi Booster for larger homes, with Ethernet cables being the best option for high-speed, stable connections to specific devices.
Add a Wi-Fi booster
Add a new Telstra Smart Wi-Fi Booster Gen 3 to an eligible Telstra nbn plan to get more consistent speeds in more rooms. Our Wi-Fi boosters create an extended network that optimises itself so your devices get more consistent speeds.
While there is no golden rule for fixing wireless network issues, the following tips and tricks may help improve the performance of your network.
The Telstra Smart Wi-Fi Booster works on all nbn connections. It isn't designed to work on ADSL or cable connections.
Minimum cost from $168 plus your chosen plan costs over 24 months.
WiFi extenders and boosters are largely the same thing, marketing terms for devices that repeat your router's signal to expand coverage, but "extenders" often create a new network (SSID) while "boosters" might just amplify the existing one, with the key difference being how they work and their impact on speed, as they can halve bandwidth but are great for dead zones. For better performance, a mesh WiFi system is usually superior for large homes, offering seamless coverage without significant speed loss.
If you have a Health Care Card or Concession Card, you qualify for a special offer: the $65 Starter Internet Plan, which includes 50GB of data and unlimited standard calls to local, national, and Australian mobiles. Telstra's home broadband plans cater to various needs, offering good speeds and data allowances.
The network coverage may differ from area to area. In certain areas it may be so low that it's not possible to access the internet, or your surroundings could cause signal interference. Solution: Check our network coverage maps for coverage information and to confirm expected signal strength and speeds in your area.
Yes, Telstra Smart Wi-Fi Boosters and Telstra Smart Modems are designed to work together.
Simply plug the range extender in, then press the WiFi Protected Setup (WPS) buttons on your router and extender. Plug the extender in where the signal from your router is strong and connect to the internet.
Here are nine easy ways you can fix a weak WiFi signal.
The best Wi-Fi booster for your home depends on your needs, but top-rated options for 2025/2026 include the TP-Link RE715X (AX3000) for overall performance and the budget-friendly TP-Link RE315 (AC1200) for single-room boosts, with Mesh Wi-Fi systems (like TP-Link Deco) being ideal for large or multi-story homes needing seamless coverage. For newer Wi-Fi 7 technology, the Netgear EXS25 offers high speeds, while the Asus RP-AX58 is praised for its smart features and security.
The extender needs to be close enough to the Wi-Fi router to pick up a strong signal to extend but far enough to effectively distribute this signal to areas where it's needed. A central location often works best, especially on the same floor as your router.
You can get a free Telstra modem upgrade to the Smart Modem 4 by signing up for a new eligible NBN or 5G internet plan, with a 24-month commitment, otherwise a $200 fee applies if returned late. Existing customers on eligible fibre connections (FTTP/HFC) may get a free technology upgrade (FTTC/N to FTTP) and new modem when joining higher speed tiers, while existing customers can buy the Smart Modem 4 for $240 or upgrade if they're on specific plans. The modem is often "included for use" with a 24-month contract, requiring return if you leave.
Unlike extenders, boosters don't create a secondary network. Instead, they improve the existing signal, allowing it to penetrate walls, floors, and other physical barriers more effectively. Boosters are excellent solutions for improving signal quality and maintaining higher speeds over a longer distance.
Follow these steps to maximize whole-house coverage:
WiFi extenders are not always reliable and can often slow down your internet connection. This is because the WiFi signal must travel from the router to the extender and back out again. As a result, even if you can connect, the speeds provided might be very slow, especially if you are far away from the WiFi extender.
Remove the power cable from your modem for 10 seconds, then plug it back in. Wait a few minutes for the modem to reconnect. When reconnected to the internet and powered up, the modem front light will be a solid green, or solid blue if you're connected to 5G or 4G Telstra Home Wireless.
Test and troubleshoot an issue with my internet
Your signal or reception can be affected by lots of things, including: Being somewhere with thick walls and windows. Using an older device. More people using the network around you.
